At SMS Technologies, I engineered a high-concurrency event lottery system in Go, using cryptographic randomness, Redis distributed locks, and PostgreSQL locking to prevent race conditions. I also implemented a tamper-evident audit trail and a double-entry financial ledger with idempotency controls.
At Ethioware - EdTech Initiative, I co-led development of a mental health platform and integrated real-time video consultations and a bilingual AI chatbot. In my Hisaab project, I reduced dashboard load times from five minutes to under two seconds with asynchronous RPC queries and Redis caching.
