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.

Chatbot Solution Review from Daria Hlavcheva
KeenEthics onboarded Lionwood Software to develop an AI-powered chatbot that could analyze photos of vehicle damage and provide an estimated repair cost for insurance company. The project focused on applying AI to a traditionally manual part of the insurance claims process. The solution needed to interpret car damage from uploaded images, identify relevant damage, and translate the analysis into a cost estimate that could support faster and more consistent claims assessment. Lionwood Software took ownership of the AI development and worked closely with the KeenEthics team to align the solution with the product requirements and insurance use case. Their team demonstrated a strong understanding of both the technical challenges of image-based damage assessment and the business logic behind insurance claims. They were proactive in discussing requirements, clarifying edge cases, and addressing dependencies throughout the development process. The resulting solution helped automate an important part of the vehicle damage assessment workflow, reducing the need for purely manual evaluation and creating a foundation for faster claims processing. Lionwood Software proved to be a reliable technology partner with the expertise to work on AI-driven products where technical implementation needs to be closely aligned with real-world business requirements.

Thanks to Wdi's expertise and dedication, the music app achieved a 400% increase in downloads within the first month of launch, demonstrating significant progress and success.
Mobile App Development Review from Abdelrahman ALMULLA
wdi took the vision we had and turned it into something even better. They built this incredibly detailed app that lets users filter hotels based on things like airport transfers, car services, or other specific amenities. Travelers can also quickly spot deals or limited-time offers with just a glance.One of the coolest parts is how the app keeps guests updated when theyre checked into a hotel - whether it's on-site events or nearby activities, theyll get notifications straight to their phone. The feedback system they added is a game-changer. Guests can send questions or share thoughts right from their rooms, and they get notified the moment theres a response.
Mobile App Development Review from Aaron Birkby
We had many very clear outcomes and timelines based on our needs that were identified before the project began. They provided regular updates and progress reports via email and virtual meetings throughout the project. Typically in two-week sprints.

Product Design Review from Sofia Diaz
I had an idea and vision, which intent helped me bring to life. We required a platform that would be usable on different types of mobile and desktop devices, as well as work on different browsers.We went through the process of designing the product and building an MVP. Their UX designer evaluated the mockups I gave them. Then, they gave me some suggestions on how to improve the product and provided a UI designer, who built the interfaces.From there, intent handled the following stages of product development. We went through several iterations based on user feedback for the MVP, and every feature was QA-tested before release. Now, we continue to improve the product on a monthly basis.

Each Altoros engineer we have worked with has been strong technically, estimated development times accurately, completed projects on time, and delivered code and projects with high quality. Beyond that, they have helped improve our thinking and approach with suggestions and ideas that were better than the spec of instructions we supplied.

Victoria Hayes's Review Sourced from Google
The decision to choose Freshcode came from above, and I was skeptical going in. We were building a remote patient monitoring dashboard for chronic disease management, and I'd seen enough outsourced projects go sideways to be cautious.What changed my mind was how they handled the first two weeks. Instead of jumping into development, they mapped our existing workflow, flagged three places where our internal process would have broken the product, and came back to us before anyone wrote a line of code.Communication was straightforward. No chasing, no major incidents. Would work with them again — and probably will.
Ellaine Ingeman's Review Sourced from Google
The team felt like colleagues, not contractors. Quick on Slack, honest when something wasn't going to work, and they never disappeared after handing things off. Eight months in, and we're still working together. And they push back when something doesn't make sense technically. That last part matters more than people think.
Dmytro Bohdanov's Review Sourced from Google
Worked with Freshcode for over 2 years. They launched an MVP in ~2 months. Easy communication, grounded expertise, proactive people. This helps them stand out from other European developers.

Bill West's Review Sourced from Google
Sarosh and his team were top notch. I can't say enough about their thorough nature and attention to detail with my project. It really fetl like having an in house development team on my side rather than an outside hire. This team not only did what was asked but continually went above and beyond to make sure that my vision was realized. I would hire them again, without hesitation!
Nathan Gould's Review Sourced from Google
I have been working with Pendoah for AI staff augmentation since December 2025, and the experience has been excellent. Their team integrated quickly with our workflow and delivered high-quality work from day one. Communication has been smooth, and they’re very responsive whenever we need support. Highly recommend them if you're looking for reliable AI talent.

Espresso Moon Reviews & Testimonials
Bradley Collins's Review Sourced from Google
Working with the guys at Espresso Moon (Scott, Doug, Tim and Dwayne) was truly a great collaboration and experience. They didn't just throw a website together for us, they helped us to reinvent ourselves. They go out of their way to get to know you and your business to the fullest extent, and that is a quality that is not often seen. If I were to recommend a web design/hosting company to anyone, Espresso Moon would be the one and only name I give. Thank you for your service and support!
Meredyth Jones's Review Sourced from Google
I worked primarily with Scott, Tim and Doug to build a fairly complicated site: Paypal/credit card payments, video training modules, a graded quiz, and issuance of a completion certificate. They were the only website company that invited me to an in-person meeting and that was tremendously helpful in me understanding how they work and them understanding my goals. Large Animal Consulting & Education launched 2 days ago and the site is running smoothly. I'm very happy with the site they designed (they also designed my logos) and am looking forward to using them to support and add to the site down the road.
Caleb Schallert's Review Sourced from Google
Doug Wheeler is the owner of Espresso Moon and he has provided my small business excellent IT technical support for our website. His team helped me out by removing malicious code that was affecting my site right after the Heart Bleed epidemic last year. He got my site back up and running so i could continue business and save my online reputation. I would recommend Espresso Moon LLC to anyone in need of a new website or mobile application because they follow through with what they promise to do, on time and on budget. They are truly a pleasure to work with!

JavaScript Development Company Hiring Guide
What is a JavaScript development company?
A JavaScript development company is a company that develops and maintains web applications and software using JavaScript, a widely used programming language for front-end and back-end development. Its expert developers specialize in various JavaScript frameworks and libraries, such as React, Angular, Vue.js, Node.js, and jQuery, delivering intuitive and user-friendly websites.
Businesses often seek the help of a JavaScript development agency to address challenges, such as:
- Lack of skilled in-house talent
- Outdated legacy systems in place
- Limited technical expertise to handle complex projects
- Tight development timeline
- Budget constraints in hiring an in-house development team
- Limited foresight of industry trends and best practices
Hiring JS development services ensures that a business’ website, software, or application has a modernized user interface and provides a seamless user experience. By partnering with a reputable JavaScript development company, businesses can unlock the full potential of their online presence, enhance user satisfaction, and drive growth.
Success story
Our team of experts handpicked this case study to emphasize the benefits of hiring a reputable JavaScript development company to drive business growth:
- Challenge: FINN, a German-based car company, struggled with organizing its operations and automating its processes as it expands to the US. However, its current subscription system relies on older technologies like manual spreadsheets and emails. The car company needed a partner to transform its internal tools to optimize workflows and make the app easy to navigate for users.
- Solution: Cheesecake Labs helped FINN’s existing engineering team automate its processes. It also modernized its back end and internal tools by adding key features in its customer portal, allowing users and team members to easily and efficiently perform tasks like ordering or making account changes. Using Node.js, Typescript, and a PostgreSQL database, Cheesecake Labs transformed FINN’s US operations.
- Results: The partnership resulted in an over 1,200+ increase in subscription for FINN. The internal tools built by Cheesecake Labs also generated significant usage, with a boost of 6,000+ page views per month.

Success story
This case study showcases the services that enables a JavaScript development agency to deliver exceptional software systems that can contribute to boosted productivity and operations:
- Challenge: A financial services company wanted a simple, intuitive application to manage resources, tasks, and projects. The goal was to replace Jira and Excel templates with a more comprehensive solution tailored to its specific needs.
- Solution: DevsData Tech Talent developed a custom-built enterprise resource planning (ERP) system with advanced features, such as automated notifications and report generation. It also features robust encryption and a comprehensive permission system powered by its JavaScript framework tech stacks, namely Vue.js, SSS, Node.js, and Express.js.
- Results: The partnership resulted in a user-friendly ERP and PM system that perfectly aligned with the client’s needs. The software surpassed Jira in terms of security and processing capabilities, becoming a core tool for day-to-day operations across business departments.
What is the typical timeline for JavaScript development projects?
The typical timeline for JavaScript development projects can take 1 to 12 months, depending on the scope, project complexity, development tools, availability and access to tech stacks and tools, and team location.
To break it down, here’s a general web app development timeline that JavaScript development companies also deploy:
| Phase | Timeline |
Initial planning and concept
| 1-2 weeks |
Designing the web app
| 3-4 weeks |
Choosing the tech stack
| 1 week |
Development phase
| 8-12 weeks |
Testing and quality assurance (QA)
| 3-4 weeks |
Deployment

How much does a JavaScript development agency charge for its services?
A JavaScript development agency typically charges between $100 and $250 per hour, depending on the scope, project complexity, seniority of developers, and location.
Here’s a table showing how JavaScript developers charge differently based on where they are based:
| Location | Price |
| Europe | €55-€125 |
| Central or Eastern Europe | €30-€65 |
| India | $20-$50 |
Since JavaScript has different frameworks, costs also differ based on the developer’s expertise, specifically:
| Framework expertise | Price per hour |
| Node.js | $75-$95 |
| React | $70-$90 |
| jQuery | $60-$80 |
| AngularJS | $85 |

Why should I hire a JavaScript development agency?
You should hire a JavaScript development agency for its technical expertise in the JavaScript programming language, from its core syntax to advanced frameworks and libraries. Beyond technical proficiency, a JavaScript development agency often strongly understands the broader web development ecosystem. This knowledge allows them to integrate JavaScript seamlessly with other technologies, creating cohesive and user-friendly applications.
Moreover, you should hire a JavaScript development agency because it:
- Has seasoned programmers with proven expertise in JavaScript
- Deploys efficient development processes to reduce development time
- Mitigates common risks in the development process
- Helps your website reach a wider audience by optimizing your website
- Increases productivity for faster time to market
- Improves customer experience through a well-designed and functional website

- Solution: Designli developed the minimum viable product (MVP) by prioritizing easy-to-implement features using CSV workflows. To accommodate various hospital systems, the JavaScript development agency designed a customizable solution where hospitals can tailor the app to their specific needs, ensuring a seamless fit with their existing infrastructure. Designli used JavaScript frameworks like AngularJS and NodeJS, along with the cross-platform capabilities of Flutter to enable a scalable backend and a versatile app.
- Results: The collaboration resulted in a successful working relationship between the AskIris and Designli teams, delivering the features needed for the app within budget and on time. With the successful deployment of the app, the client saw tangible improvements in a hospital’s supply room efficiency and streamlined inventory management.
