LYQX Reviews & Testimonials

UI/UX Design Review from Vas Grygorovych
We partnered with LYQX to design and build the mobile experience for our e-commerce marketplace. We needed a team that could cover the full cycle UX research, UI design, Flutter development for iOS and Android, and backend integration without us having to coordinate several separate vendors. LYQX started by mapping the key marketplace flows for both buyers and sellers: onboarding, product discovery and search, listings, cart and checkout, order tracking, and seller management. They turned this into a clear design system and clickable prototypes, which made it easy for our stakeholders to give feedback before development began. The Flutter build then followed the approved designs closely, and the team integrated payments, notifications, and our existing backend APIs. What we valued most was their product thinking. LYQX did not simply execute tickets they questioned assumptions, suggested simpler flows where our requirements were overcomplicated, and flagged risks early. Communication was consistent, with regular demos and quick responses when priorities shifted. A few integration points took extra iterations because our own API documentation was incomplete, but the team handled it proactively and kept us informed. Overall, LYQX was a reliable, product-minded partner, and we would work with them again.

Web Development Review from Joanna Bauza
The work was finished in a reasonable time. Although we went past our original deadline, this was expected for a project like this. We also asked for last-minute changes, which added to the delay. The team listened to our feedback, made the changes we needed, and worked with us patiently to get everything right.

Web Development Review from Ahsanul Hasan
The project was completed on time and within budget, and their communication throughout was top-notch. They were always available to answer questions, provide updates, and offer suggestions when needed.

Software Development Review from Vladyslav Sorochan
A true tech partner who just gets it! Aqe has brought our rough software concept to life and turned it into a smart platform. The project covered everything from custom development to AI features and some pretty advanced data engineering. From the beginning, their team really took the time to understand what we were trying to achieve. They started with a clear discovery phase and built a solution that checked all the boxes in terms of functionality and ease of use.It is easy to work with their team, not only in terms of technical skills but also in how responsive and collaborative they are. They regularly improved features based on our feedback as we moved along and were always available when we needed support, even after the post-launch. Having that kind of ongoing help made a big difference.The results were a bit better than we expected. We saw a noticeable drop in manual work, smoother internal operations, and improved decision-making through real-time data.Overall, Aqe and their team really delivered what they promised, on time and within our budget. The whole experience was smooth, professional, and well-managed. Wed happily recommend working with them.
