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.

Steve Fecske's Review Sourced from Google
Internet Soft stepped in as my development team providing their team of programmers to my platform. They are a group of talented, skilled, and conscientious in everything they do, assigning the best people they have to the various types of technology I needed from UI/UX, php, API, and database. They adopted my platform as theirs and immersed themselves to learn the processes, concepts, and workflows needed to fulfill the promise of our platform's services. They apply their technical skills to understand and write the necessary algorithms. They work hard and diligently to get projects fully defined before undertaking, and then get it done on time. They test their work, present it to our marketing team, then tweak, then provide public testing, and only when ready, open full access to the target audience and advertising. They are well organized to execute our needs by providing a project manager and project leader who communicate with me as to what I want, select the right development talent, and then present it to them so they understand what is required. They have also given me direct access to the developers to further ensure they understand my vision and needs. I have enjoyed their hard work and we have endured the details. I look forward to the results, and proudly recommend Internet Soft for your technology.
Jenya Babadzhanova's Review Sourced from Google
Internet Soft is a great company with managers and employees that are motivated, reliable, and persistent in whatever they do. Their strong work ethic can be seen in the mobile apps and software development projects that they create. They keep up with industry trends and always keep the client first in mind. I highly recommend their services to anyone looking to start a tech project.
