Building systems that hold up under load

I'm a full-stack developer who spends most of my time on the backend — designing APIs, services, and data layers that stay correct under concurrency and real traffic. I've built payment gateways, remittance platforms, notification systems, and AI-powered learning products.

I work across Go, Python, and TypeScript (NestJS, FastAPI, Gin) with PostgreSQL and Docker/Kubernetes. I also ship mobile and web frontends when the product needs a complete loop — from Expo/React Native to Vue and Nuxt.

BSc Electrical & Computer Engineering graduate from Addis Ababa University and alum of Africa to Silicon Valley (A2SV, Nov 2023 – Nov 2024), where I completed 800+ algorithmic challenges on LeetCode and Codeforces.

Data consistency under concurrency is not optional — atomic transactions, clear locking, and explicit error handling beat clever shortcuts every time.
