Software Development Review from Anonymous
We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs. Talentica was brought on board to test and refine the concept from both functional and engineering perspectives, and later to build a Minimum Viable Product (MVP) aligned with the agreed specifications and constraints.

Software Development Review from Anonymous
For several years, the team was composed entirely of Talentica contractors. Since January 2022, I have been directly managing them. The Talentica team handled the admin tooling backend, which included multiple Python Flask services with Postgres and Elasticsearch. These services operated in a service-oriented architecture deployed on Kubernetes, using Istio for service mesh and Spinnaker for deployments.

Software Development Review from Robert Hager
Itransition carried out the entire software testing process without a single delay. Despite the remote cooperation, the company ensured ceaseless communication, which indicates a high level of the team’s professionalism and organization.

Software Development Review from Jimmy Carlisle
We needed an in-depth upgrade of the legacy auditing system. We chose Itransition because they swiftly responded to our project requirements and had relevant expertise. The team helped us decide on the solution’s tech stack and designed the new architecture, migrated legacy data, developed new features, and customized the software with extensions. We got a powerful and user-friendly auditing system and were very impressed with the Itransition’s dedication and attention to detail.

Software Development Review from Shoshana Parker
We enjoyed working with Itransition. We needed a solution for transferring health records from our EHR into the data warehouse without losses. We chose Itransition for their experience, portfolio, and past clients’ references, and the team fully met our expectations. They built a custom ETL tool that increased our visibility into clinical data and helped us spot inefficiencies in patient workflows. Needless to say, they also delivered it on time and budget.

John Andesilich's Review Sourced from Google
I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

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.

The exception team the client collaborated with brought in fresh ideas and innovative technologies previously unfamiliar to the client. For example, with Yalantis' guidance, the client's developers explore the Go language. The primary reason the client chose Yalantis is its strong organizational and project management skills. It's not just about the developers; Yalantis provides a comprehensive support framework, ensuring that a project manager is consistently present. (Verified via email)

Flyaps Reviews & Testimonials

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.

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
Taking premeditated measures such as documentation updates, code optimization, and data backup to safeguard against potential issues and vulnerabilities - Perfective software maintenance
Amplifying functionality to fulfill the users’ needs by adding new capabilities, implementing user feedback, and removing outdated and ineffective features - Adaptive software maintenance
Implementing software changes to adhere to new business policies, changing regulatory requirements, or software and hardware updates - Backup and disaster recovery
Backing up software data and establishing processes to quickly restore operations in case of a disaster or emergency - Quality assurance
Conducting rigorous tests to identify and resolve functionality defects and ensure the software aligns with the latest practices, regulations, and quality standards - Product migration
Transitioning an existing product to a new platform or technology while maintaining data integrity and functionality
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.
How do I choose the best software maintenance company for my business?
