Backend Developer for Playful App with Pickup Lines & Memes
Usman did a great job helping refine and finalize my app project. He was fast, responsive, and handled the existing codebase smoothly without pushing for a rebuild. Communication was clear, timelines were realistic, and he delivered working updates on schedule. I especially appreciated how he explained technical steps and structured milestones fairly.
Would definitely recommend him for mobile app MVP builds, Firebase setup, and AI integrations — solid dev to work with.
