Software Engineer • Lagos → Anywhere
Hi, I'm Chisom. I build AI, backend, and frontend systems that real users depend on.
From RAG pipelines and APIs to healthcare interfaces and a mobile marketplace, I take products from architecture to production.
About
I’m a software engineer based in Lagos, Nigeria, building products that solve practical problems, from healthcare platforms to AI-powered systems.
I’m the founder of vWorka, a job marketplace for blue and grey-collar workers. I built the first version solo on WhatsApp, grew it to 300 users, and used their feedback to design the mobile app launching in December. I also built the full client at Tracmedy and ClauseGuard, a multi-agent RAG system for contract risk analysis. I care about maintainable systems, performance, and product decisions that make sense beyond the code editor.
