Backend-focused developer at AfroDigital who cut delivery time by 50% with a reusable NestJS foundation.

Message

At AfroDigital Innovation Labs PLC, I built a reusable NestJS backend foundation that became the company standard and helped reduce product delivery time from six weeks to three. I also lead development for client products and build custom AI solutions.

As lead developer for Tibeb, AfroDigital’s integrated health platform, I built a multi-vendor pharmacy marketplace with prescription uploads, online doctor consultations, and automated vendor payouts.

I founded Parsim, an inference and context-management layer for long-horizon AI agents. It cut context tokens by 74–89% through garbage collection and up to 92% with background LLM summaries.

I also founded YeneSchool, an AI-driven school operating system for Ethiopian schools, and BioMatch, an AI-powered organ donor matching platform recognized as a top startup at Lead Business 2025. At BITS College School of Systems and Technology, I teach programming and data structures while building backend features for a therapy management system.
