Software Development Review from Slava Kostiuk

We initially approached UASOFTDEV with a relatively straightforward request: a WordPress website and a Senior React/Node/Python Developer for backend and API development. What impressed us immediately was how quickly they understood our needs and delivered relevant candidates. We received the first 5 candidates within 60 hours, exactly as promised. The developers were skilled, experienced, and cost-efficient, so we decided to continue working with UASOFTDEV. Later, we returned with a much more complex project: an already-live AI beauty ecosystem combining a Smart Mirror, mobile app, AI skin analyzer, and AR makeup. This required a Senior Flutter Engineer who could join an existing team and work with Flutter, Banuba SDK, Java/native technologies, and a production environment. UASOFTDEV matched us with a senior Flutter engineer within 60 hours. He integrated quickly into our existing team and provided the 24/7 production support we needed. During the 5.5-month engagement, we delivered 10+ major features, shipped 15+ releases across 3 product environments, and launched 2 premium subscription features. What we valued most was the consistency of their approach. Production issues and new feature requests were handled quickly, communication was personal and responsive, and the team remained highly engaged throughout both projects. The fact that we came back to UASOFTDEV with a second, significantly more technically demanding AI/AR project is probably the strongest proof of our satisfaction. They successfully scaled from a simple staffing request to supporting a complex live product without losing the same level of responsiveness, quality, and personal attention.

Dedicated Team Augmentation Review from Leonid Viktorov

I am the CEO of Biz Adviser, a business consulting company. We work with companies on strategic business initiatives, digital transformation, and improving business performance. We partnered with UASOFTDEV when we urgently needed additional engineering capacity. I was looking for proven senior developers and did not have time to spend weeks sourcing candidates and conducting multiple interviews. UASOFTDEV offered to provide vetted Ukrainian developers within 60 hours, which was exactly what we needed. The team provided senior engineers with strong technical expertise and excellent communication skills. We worked with developers across PHP, Node.js, Python, and React, depending on the project requirements. They were reliable, proactive, and able to understand not only the technical tasks but also the broader business context. The developers contributed to several important initiatives, including the implementation of an AI agent, and helped us move projects forward faster while keeping development costs under control. UASOFTDEV delivered what they promised. The process was straightforward, communication was reliable, and the developers were able to start working quickly without compromising on quality. The pricing was a good fit for our budget, and the overall value for cost was excellent. I also appreciated the cultural fit and the team's ability to communicate effectively and take ownership of their work. I would definitely recommend UASOFTDEV to companies looking for reliable staff augmentation with senior Ukrainian developers. They are a trustworthy partner that can provide strong engineering talent quickly and help businesses deliver important initiatives without the overhead of a lengthy hiring process.

Software Development Review from Robert de Burgh-Day

KeenEthics has been our software development partner at Brightspace for our analytics dashboard platform, and the experience has been consistently excellent. As a hardware and AI company, we needed a team that could take complex real-time occupant and environmental data from our edge devices and turn it into dashboards that facility managers and building owners actually want to use. KeenEthics delivered exactly that. What stands out most is how they work. Communication is clear and proactive, sprints run on time, and when requirements shift, as they inevitably do in a fast-moving startup, the team adapts without drama. They ask the right questions early, push back constructively when something could be done better, and take genuine ownership of the product rather than just ticking off tickets. The quality of the work speaks for itself. The dashboards they have built are now a core part of our commercial offering across multiple markets, and they have held up well as we have scaled deployments. Costs have been fair and predictable, which matters enormously for an early-stage company. I would not hesitate to recommend KeenEthics to any company looking for a reliable, high-quality development partner, and we intend to keep working with them as Brightspace grows.

Web Development Review from Khrystyna Sliana

We collaborated with this company while supporting our client with a request focused on a TypeScript, Node.js, and Angular stack.After engaging them through our partner network, they quickly shared a strong candidate who turned out to be an excellent match for the clients needs. The developer demonstrated solid technical expertise and professionalism throughout the entire engagement, which was highly appreciated by both our team and the end client.At the beginning of the collaboration, there was a need to adjust the developers working schedule. Keenethics handled this situation very efficiently, resolving it within a few days and ensuring full 8-hour availability. Their responsiveness and problem-solving approach made a strong positive impression.We are very satisfied with both the quality of the specialist provided and the company's ability to react quickly and effectively to operational challenges.
