ELEKS Reviews & Testimonials
Software Development Review from John Armstrong
ELEKS was able to take our vision and help us deliver an app that empowers retail shareholders to make their voices heard. They’ve brought a depth and breadth of technical expertise and user experience design to challenge us on our assumptions on how people would want to interact with the app. From a mobile development perspective, we wanted to go to market with both an Android and an iPhone simultaneously.
Software Development Review from Mark Battcock
We are very happy with our ELEKS partnership; the dedication of the team is exceptional. We would certainly recommend ELEKS and would be happy to work with them again. In fact, they continue to be our partner for the 2nd phase of the CDX project to add even more customer services to the website.
Software Development Review from Huntly Christie
What impressed me about ELEKS is the culture. There is a very strong culture of discipline and performance, and software is a profession where discipline is very important. Good software development can only happen with a strong work ethic, and I think the ELEKS team really understands that.

Python Django Review from Andrew Stetsenko
We partnered with Flyaps to build the GlossaryTech Chrome Extension from scratch, including the backend for tech terminology analysis. The goal was to help recruiters, sales professionals, and other non-technical specialists in IT quickly understand the technical terms they encounter every day.The first release shipped back in 2017, long before today's AI tools were available off the shelf. Flyaps built a custom tokenization layer on top of NLTK library to resolve the ambiguity problem - distinguishing "Go" the language from "go to the shop," or "Swift" the framework from the adjective, while also correctly recognizing multi-token terms like "Ruby on Rails" or "Amazon Web Services". It was a pragmatic, precise solution that made the extension genuinely usable from day one.The outcomes have validated that early bet. GlossaryTech now holds "Featured" status in the Chrome Web Store, has passed 25,000 downloads, and consistently serves 10,000+ weekly active users and 2,000+ daily active users. For a niche professional tool, that level of organic, sustained engagement is rare - and it traces directly back to the technical foundation Flyaps put in place.Beyond the engineering, what stood out was how Flyaps engaged with the product itself. They contributed to architecture decisions, flagged edge cases early, and treated scope conversations with honesty rather than upsell. Communication was straightforward throughout, deadlines were met, and the codebase has held up well as we've extended the product over time.I'd recommend Flyaps to anyone looking for a partner who combines solid engineering with genuine product thinking. They've been central to GlossaryTech's success and continue to be a team we trust.
Software Development Review from Dariia Ryzhova
Our collaboration with Flyaps has lasted for several major projects, of which I personally worked with them on two. I am very satisfied with the level of expertise (both technical and domain), the involvement and responsibility of the teams, and the quality of delivery. We successfully brought 2 major products to life together. Flyaps teams have diverse specializations, so I had the opportunity to attract consultants from different fields: software developers, including high-level architects, DevOps, QA, and business analysts.The teams have a modern technology stack and are experienced in Agile development. This allowed for smooth integration with internal teams and processes. It is also important to note that Flyaps provides technical consulting on demand, and this was very valuable service as well. Overall, I can recommend working with Flyaps as a reliable and high-quality partner.
ТОВ ХОТНАЙТС's Review Sourced from Google
Flyaps delivered outstanding results for our e-commerce store! They built a visually stunning and high-performing website that perfectly captures our brand. Since launching, our site speed has improved by over 60%, and we've seen a noticeable increase in our conversion rate. Their team's technical expertise is top-notch, and the new admin panel they created has made managing our operations so much easier. I am happy to recommend this team of professionals.

Mobile App Development Review from Elvera Kaparchuk
SaveIT is receipt management on autopilot. You connect your email once, and we import your receipts, extract every line item with AI, categorize it, and sync it with QuickBooks. The AI isn't a feature of the product, it is the product. If it reads a receipt wrong, everything downstream is wrong. We brought Diffco in to work on that core. Since April they've worked on our AI models, fixed security problems in the platform, and helped us build a real strategy around where AI belongs and where a conventional solution is the better call. The most important change was measurement: extraction accuracy is now a number we evaluate every change against, instead of something we judge by trying a handful of receipts. They were also honest in a way I didn't expect from an AI firm. When we assumed a problem needed a stronger model, they showed us it was in our data. That saved us time and money. They continue to support the AI side of the product, and they're easy to work with; direct, technically deep, and clear about trade-offs.
AI Development Review from Ivan Pasichnyk
We brought Diffco in to deliver the AI and computer vision components for one of our clients, an image generation startup. Because the work sat inside our own client relationship, we needed a partner we could trust to operate at our standard without us managing them day to day - and that is exactly what we got. Diffco owned the technical approach, built the computer vision and AI layer, and delivered the full scope in three months, on schedule. The engineering quality was high, they raised the right questions early instead of late, and they handled the confidentiality the project required without us having to chase it. After delivery they stayed on to support the system, which mattered to us as much as the build itself. When you subcontract a technical project inside your own client relationship, the risk is that the partner makes you look bad. Diffco did the opposite. They've earned our trust and we'd work with them again.
AI Development Review from Oleg Sotnikov
Diffco built a complex, production-grade AI agentic system and backend for our client's fintech platform owning architecture, AI/ML components, and AI agents in a security- and compliance-sensitive environment. They delivered on time and within budget, communicated proactively, and operated like part of our own team, taking ownership and suggesting better solutions throughout. Deep AI/ML and senior backend expertise. We'd happily work with them again.

Software Development Review from Daniel Rondell
We are notably satisfied with the upshot. PMs and development team was very devoted to the tasks and encouraging. We had a stringent and fixed deadline. And we got it just in time! KitRUM helped us to create an entire software that absolutely meets our requirement. They had presented the system in a short-term after putting their hands on it. They also provide support after developing this software. We have a different project now and certainly will work with KitRUM again.
Software Development Review from Adelina Romanova
KitRUM expanded our team to shift software to a new platform. Using JavaScript and RESTful APIs, they improved interfaces and DevOps, and fixed bugs. The team has always been on time. Their ability to understand the business requirements and their communication was just perfect. I definitely will recommend KitRUM as a reliable partner.
Software Development Review from Daisy Skot
KitRUM made a variety of development services: conception, coding, and QA, which means almost a full software package for our company. We needed to develop a few tasks, for example, a desktop app for our store, a cloud app for administration and supervision, and a portable app for end customers. However, we had an in-house team, which is not enough for this project. So we had to find a dedicated team that could deliver all we needed. We found KitRUM as a top-notch software development company

Acropolium Reviews & Testimonials
Software Development Review from Iryna Liashko
We engaged Acropolium as a development partner to support delivery of a SaaS-based warehouse management system for our end client. They handled key backend components, third-party integrations, and overall system architecture alignment. The engagement ran from May to September 2025.Acropolium took full ownership of complex technical components and worked as a seamless extension of our internal team from day one. They required minimal supervision, communicated proactively, and adapted well to changing requirements throughout the project.The results were strong: our end client saw a 30%+ improvement in order processing efficiency, a significant reduction in manual operations and errors, and smooth integration with existing systems.We were thoroughly impressed by their technical quality, reliable delivery, and professional approach. Deadlines were consistently met, and the team responded quickly to feedback. The collaboration was smooth from start to finish.We would confidently work with Acropolium again and highly recommend them as a trusted software development partner.
Startups Software Development Review from Viacheslav Koziura
Acropolium provided a highly skilled team for our short-term project. We had strict deadlines, and they helped us deliver everything on time. Beyond just supplying developers, they also contributed valuable expertise that improved the overall outcome. It was a smooth and professional collaboration.
Node.js Review from Oleksandr Romanov
We partnered with the team to support the integration of AI capabilities into our existing Node.js tech stack, and the experience exceeded our expectations. From the very beginning, they demonstrated a strong understanding of both backend architecture and modern AI tools, which allowed them to quickly align with our business goals.Their approach was structured and transparent: they helped us choose the right AI models, designed scalable integration flows, and ensured smooth interaction between services without compromising performance. Communication was consistent, deadlines were met, and any challenges were addressed proactively.What stood out the most was their ability to bridge the gap between complex AI concepts and practical implementation within a real production environment. As a result, we significantly improved our products functionality and reduced time-to-market for new features.I would highly recommend this team to anyone looking to integrate AI into a Node.js-based system in a reliable and efficient way.

Software Development Review from Ali Krynitsky
We first met the Cybergizer team at a conference where they talked about their experience with AI in healthcare. Around that time, we were actually looking for a solution to turn doctor-patient conversations into written documents using an LLM speech-to-text model. The idea was to generate a summary that could later be shared with the patients family.The tricky part was getting the model to handle all the complex medical terms doctors use and making sure the output was accurate and reliable.Cybergizer jumped in and helped us get everything up and running super fast. Thanks to their support, we were able to deliver the solution to our client in record time and basically save the whole project (and the client's business too).They were incredibly flexible with processes and approaches, which really mattered since the whole situation was pretty unconventional with tight deadlines and lots of legacy issues.Were still working with Cybergizer on other parts of our business and can honestly say theyre a great partner to have on your side.

Steve Molander's Review Sourced from Google
Oversight of our databases have always been a challenge. Finding the skillset to properly administer the systems is both difficult to find and high priced for a mid-sized organization. We reached out to Emergent to find out more about their virtual dba services. Their services sounded to be exactly what we needed. That was over 4 years ago. Since then we found Emergent to be a key partner in helping us in administration of our databases. Our systems are highly efficient, highly available and we feel secure knowing they are under the oversight of some amazingly skilled engineers.

Faced an unprofessional experience with Enspirit. HR initially responded quickly and asked for my details, but later kept delaying, saying the technical team was unavailable.After 15 days of waiting, I was told they are now only considering more experienced candidates. Wasted my time with unclear communication.

Software Maintenance Company Hiring Guide
What is a software maintenance company?
A software maintenance company is a specialized IT company that optimizes software products to ensure they remain agile, functional, and aligned with the latest technological advancements. Its core focus is maintaining software quality by eliminating bugs and glitches, improving user experience, and supporting product growth and scalability.
As part of its software maintenance and support services, this agency also helps businesses resolve some of the following challenges:
- Crashing and poor-performing software
- Low user engagement and high user churn rate
- Inability to integrate with operating and data systems, API versions, and communication protocols
- Incompatibility with newer devices and their operating systems
- Reliance on legacy code, which can incur higher maintenance costs and hinder integration with modern technologies
- Inability to comply with the latest international regulations
- Limited in-house expertise and resources for software development, testing and maintenance
- Frequent cybersecurity incidents across existing software
Valued at $209 billion in 2023, the software maintenance service market is predicted to reach $807 billion by 2031, with a compound annual growth rate (CAGR) of 18.45% from 2024 to 2031. The market is projected to grow due to the increasing need for operational efficiency and evolving customer demand for digital solutions.
Success story
For a more concrete understanding of what software maintenance companies can do for businesses, we selected this case study from ELEKS:
- Challenge: Network solutions provider Medusabusiness partnered with ELEKS to re-engineer and update its flagship product, Medusa, that was approaching the end of its technological and economic lifecycle.
- Solution: ELEKS reworked Medusa's architecture on the cloud and updated its traffic routing. Then, it produced a minimum viable product (MVP), performed quality assurance, and implemented self-service functions. ELEKS also provided continuous support and maintenance, integrating off-the-shelf solutions to support the client’s evolving needs.
- Results: Through its specialized expertise in network routing and software engineering, ELEKS ensured zero issues for 90% of Medusa’s upgraded features, which saved Medusabusiness 40% on operational costs and 20% on support efforts. Moreover, the enhanced product led to a 10% customer growth.
What do software maintenance companies do?
Software maintenance companies modify and update websites, applications, and other systems to resolve issues that have manifested post-launch and improve the product’s overall performance. This allows the solution to stay effective, competitive, secure, and adaptive to evolving technologies and industry standards.
Key software maintenance services include:
- Software audit
Analyzing the software to assess overall quality, test for issues, and measure it against a business’ envisioned objectives and the latest standards and regulations - Hosting and infrastructure maintenance
Managing servers, databases, and other software infrastructure components to ensure undisrupted operation and scalability - Bug/Corrective software maintenance
Repairing minor software defects that impact the app’s overall functionalities, like bugs, glitches, errors, and faults - Preventative software maintenance

Success story
To showcase software maintenance services in action, we have selected this case study from iQuasar:
- Challenge: A commercial process improvement company engaged iQuasar to migrate and update its existing application, originally built with an outdated version of VC++ and C#. The application faced several critical issues impeding its scalability and maintenance, including fragmented and overly complex code, inefficient workflows, incomplete documentation, incompatible external library dependencies, outdated UI/UX, and outdated technologies and plugins.
- Solution: iQuasar upgraded VC++ and C# to the latest version, including the attached components. It also consolidated and organized the codebase, enhanced code readability, optimized the code image, implemented a stable and adaptable workflow by decoupling select modules, and audited and upgraded the external library. Moreover, iQuasar focused on producing a modern and user-friendly UI/UX design and provided comprehensive project documentation that followed the industry’s standardization practices.
- Results: The collaboration with iQuasar led to a more robust, stable, efficient, and future-ready application with increased performance longevity and user satisfaction.
What is the difference between software maintenance and support?
The difference between software maintenance and support lies primarily in their scope of work. Software maintenance involves ongoing improvements and updates throughout the entirety of the software development lifecycle to ensure long-term product value in the long term, including bug fixes, performance optimization, and feature enhancement. In contrast, software support addresses immediate user issues, provides quick fixes and troubleshooting, and helps end-users effectively use the product.
Other key distinctions include:
| Software maintenance | Software support |
| Assists companies supplying the software | Provides assistance to end-users |
| Resolves issues that impact software’s function, performance, and other aspects | Fixes short-term functional issues that impact user experience |
| Services include updating code and features, optimizing performance, fixing bugs, implementing security and preventive measures, and ensuring environmental adaptation | Services include troubleshooting, user training, remote assistance, and onsite support |
How much do software maintenance services cost?
Software maintenance services cost between $5,000 and $50,000 per month. Enterprise software maintenance fees can reach up to 70-90% of the total cost of ownership, while fees for mobile and web app maintenance amount to 15-20% of the original development costs.
The range of these costs can vary significantly, depending on several factors:
- Type of maintenance
- Age of software system
- System complexity
- Hardware stability
- Number of new features, functionalities, and integrations
- Number of internal and external users
- State of documentation
- Length of agreement
- Agency location and expertise
Why should I hire a software maintenance service?
You should hire a software maintenance service to resolve software issues, scale your software product, and ensure that it remains valuable to your target users, ultimately, contributing to your business continuity and profitability. Outsourcing such a service allows you and your team to focus on core business activities while you rely on an expert team to optimize your software.
Software maintenance companies can also help you:
- Improve product reliability by fixing arising problems, including bugs, slow-loading systems, and poor-performing features
- Improve software efficiency by optimizing codes and retiring outdated functions
- Elevate user experience by updating or adding new capabilities that meet users’ needs
- Increase cost-efficiency, as software maintenance companies can provide you access to professional tools, software, and technology
- Extend product lifespan by keeping it up to date with the latest hardware and software systems
- Improve user adoption through application programming interface (API) integrations and software interoperability
- Navigate the security and privacy regulations of different regions
- Migrate legacy software without losing valuable data and key software functions
- Safeguard against sophisticated cyber-attacks
Success story
To further emphasize the befits of hiring a software maintenance company, we handpicked a case study from Origina:
- Challenge: Trustmark National Bank (TNB) faced a complex challenge in moving away from IBM after an unfavorable three-year agreement. With IBM proposing significant fee increases for renewed support, the bank sought to avoid a new multiyear commitment while maintaining essential support for its software. To manage this transition, Trustmark required a skilled maintenance partner to sustain its current software without extending reliance on IBM.
- Solution: TNB entrusted Origina to manage and support 85% of its systems. The agency maintained all versions of TNB’s IBM software, provided expert guidance on software licensing, and helped TNB migrate away from IBM’s support while ensuring compliance with financial industry regulations. It also produced custom software for products that TNB decided to discontinue in the long term and implemented robust cybersecurity to all systems.
- Results: TNB secured over $5.5 million in savings, gained control over its software lifecycle, and increased operational efficiency and security.
