🏆 Top Rated Plus on Upwork | 100% Job Success | 5⭐️ on every completed contract. I'm a senior full-stack developer who builds modern web and mobile apps end-to-end — frontend, backend, AI, cloud, and DevOps.

Highly recommend!" "Dawit is a clear communicator and very professional. I truly enjoyed working with him and highly recommend him." Repeat clients have endorsed me as Reliable, Detail-Oriented,Committed to Quality, and a Clear Communicator. 🛠 How I work Clear scope up front, milestone-based delivery, daily or weekly updates (your call), and clean documented code any future dev can pick up.
