      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.

      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.

      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.

      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.

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.

      We hired Altoros engineers as an essential extension of our client-facing internal teams. This was a tough decision because our reputation as a brand depends on the overall efficiency of our processes and we needed to make sure all risks are mitigated when it comes to delivery. Altoros has not let us down.Together with Altorosians we successfully deployed a number of tough and technologically complex projects on time. So our collaboration is certainly set to continue.

      In my 30 years in the software business, I have never had as positive an experience with an outsourced development services provider as I have with Altoros. 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.

      David B's Review Sourced from Google

      I want to share my experience so others are aware of the tactics this company uses. I was first contacted via an unsolicited spam text message promoting app development services. I had never heard of this business before, nor did I request any information from them. To see who was really behind the spam, I replied with a simple question about app pricing. The next day, I was contacted directly by this company.What was most concerning is that they tried to claim I had emailed them asking for their services — which is completely false. I never sent them an email or initiated any legitimate contact. The only reason they had my information was because of their own spam outreach. This is both misleading and dishonest.Professional companies do not need to resort to spamming strangers or fabricating stories about how potential clients found them. This type of behavior demonstrates a serious lack of transparency and integrity. If a business cannot be upfront and honest during the very first interaction, it raises major red flags about how they would handle a client’s project, communication, data, and money over time.Based on my experience, I cannot recommend this company. Trust is one of the most important parts of choosing a development partner, and unfortunately, their conduct showed me they are not worthy of that trust. I strongly advise anyone considering working with them to be cautious and look elsewhere for reputable professionals.
