Full-Stack Engineer at BlackBridge Technologies, delivering OneHR features for enterprise clients and building HR data integrity tools.

Ethiopia

Message

At BlackBridge Technologies, I deliver production features for OneHR, a 26+ module HRIS serving enterprise clients. I migrated HR data from Firestore to MongoDB and PostgreSQL, and developed a checksum-based audit engine to detect corrupted reporting relationships and generate atomic repair plans.

At Africa to Silicon Valley (A2SV), I built a student progress platform used across three universities and a browser extension that submits LeetCode and Codeforces solutions directly to the platform. I also led the backend team for DineQ, an AI-powered menu digitization MVP, and engineered a low-latency order-matching engine for TradeFlow MicroSim.
