I'm a Software Engineer focused on Backend (Go, Nest.Js) and DevOps — building reliable systems and full-stack solutions for teams and products.
From intern to contributor: I've shipped fixes and features at BrainBite, work on full-stack at Züs, and back-end at Addis Ababa Innovation and Technology Development Bureau. I work with Go, NestJS, Node.js, PostgreSQL, Docker, and CI/CD so things scale without breaking.
