Web Design Review from Yiannis Kaznessis
Our website was established and redesigned by Brightlab, and it receives a lot of traffic. Our interaction with Brightlab team was exceptional. They were dependable, communicative, and responsive. They were really easy to work with and quickly grasped what I was striving for. Additionally, there weren't many mistakes to fix after development. Incredibly capable and productive team!

UASOFTDEV Reviews & Testimonials

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.

DevOps Consulting Review from Khrystyna Sliana
We hired a DevOps engineer from UASOFTDEV to handle a multi-entity AWS infrastructure split. The project was completed on schedule, with zero downtime and great attention to security and data integrity. Recommended.

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.

Appingine Reviews & Testimonials
David Dorough's Review Sourced from Google
I read reviews of almost 100 companies and spoke with reps from 5 before finally going with Appingine for my first app. I'm sure you can pay more for less quality from a different company but why would you? They were easy to work with and quick to respond to questions. They split the charges by stage of development like every professional company should.I needed to make several changes during development and the cost was reasonable. Anthony was awesome and helped me along every step of the way. Apple has more stringent requirements than Google and Appingine was able to get the app published on both stores. Looking forward to more projects with them. Once again, don't pay more for less, go with Appingine!

Bacancy Reviews & Testimonials
Gordon Nall's Review Sourced from Google
Over the past five years, we have steadily expanded our relationship with Bacancy Technology, increasing the number of engineers we engage through their team. As our partnership has grown, so has the value they deliver.What has impressed me most is how effectively their engineers have self-organized, shared knowledge, and cross-trained one another. Rather than operating as individual contributors, they function as a cohesive team, collaborating on complex challenges and supporting each other's success.Over time, we have entrusted them with increasingly critical and technically demanding work. They have consistently delivered high-quality results with minimal oversight from our onshore engineering team. Their professionalism, technical expertise, and ability to take ownership have made them a valuable extension of our organization.I would highly recommend Bacancy Technology to any company looking for skilled, reliable engineering talent and a true long-term technology partner.
Kunal Chavda's Review Sourced from Google
We partnered with Bacancy Technology for a mid-scale development project, and the overall experience was very positive. Their team demonstrated solid technical skills, especially in understanding our requirements and translating them into practical solutions. Communication was smooth, deadlines were respected, and any challenges that came up were addressed quickly and professionally.What I appreciated most was their structured approach and the consistency they maintained throughout the project. The final delivery met our expectations, and the support they provided post-launch was equally dependable. Good choice if you’re looking for a team that’s accountable and technically capable.
Thomas's Review Sourced from Google
Paid $3,560 for web development—received no usable work, no deliverables, and no meaningful communication. Contractual obligations were ignored. Extremely disappointing experience.

Farha Mansuri's Review Sourced from Google
I had a very disappointing experience with their walk-in interview process. They posted about a walk-in drive along with a Google Form for registration. Nowhere in their LinkedIn post did they mention that candidates would require a personal invite to attend.I filled out the form and traveled over an hour in 40-degree heat while fasting, only to be told that I hadn’t received an invite and couldn’t interview. If a personal invite was mandatory, this should have been clearly communicated in the post. Additionally, if they were selecting candidates, they should have at least sent a rejection email so people wouldn’t waste their time traveling.This kind of poor organization and lack of communication is highly unprofessional. It reflects badly on the company and makes candidates feel like their time and effort are not valued. I hope they improve their process in the future to avoid misleading applicants.
