Hi, I'mOlyad B.
I build systems
that never break.
I'm a Software Engineer focused on Backend (Go, NestJS) and DevOps — building reliable systems and full-stack solutions.
From intern to contributor: I've shipped features at BrainBite, worked full-stack at Züs (decentralized cloud), and back-end at Addis Ababa Innovation Bureau. I work with Go, NestJS, Node.js, PostgreSQL, Docker, and CI/CD so things scale without breaking.
