Software Engineer
Backend-first. Full-stack when needed.
I ship full-stack features when needed, and I'm most at home on backends, DevOps, and Telegram bots. I care about reliability, clean structure, and products people actually use.
A bit about me
Software engineer based in Addis Ababa. I work across the stack and go deepest on Backends, DevOps, and Telegram bots.
I've shipped APIs, learning platforms, payment tools, bots, and the infra that keeps them running, and I step into frontend when the product needs it.
I like owning delivery end to end: clear goals, solid builds, and reliable deploys.
