Software Development Review from Lori Feld Oakley
Our Services organization is scaling quickly and we urgently needed a custom software application to automate our workflows, without breaking our annual budget. CodeStringers was the perfect fit, supporting us from ideation through go-live and everything in between. They innovated, hit their deadlines and released an amazingly high quality application that decreases our internal costs and improves our reputation with our customers. It would not have happened without CodeStringers.

CodeStringers is the perfect outsourcer to call If you have a solid software business idea but don’t know exactly how to bring it to life. They have both a top-notch development team as well as an executive staff with expertise in marketing, finance, and general business acumen.

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.
