Message

I've built production backend systems at Doheney Services, JeGO USA, and Sanctum Nigeria, including real-time processing handling 10K+ daily events at under 100ms latency, FastAPI services with caching that cut redundant calls by 40%, and a retrieval pipeline that improved search relevance by 40%.

I work across REST APIs, PostgreSQL, vector databases, Docker, cloud infrastructure, and performance optimization. I've also built route optimization and solar tracking services, led technical sessions for 15+ engineers, and founded Cave.AI Hub to help engineers ship real production systems.
