What I'm looking for

I'm immediately available for full-time remote, hybrid, or on-site work where I can build scalable, user-centric products, strengthen backend architecture and performance, and contribute to collaborative engineering teams.

I lead architecture and marketplace operations for Ajaawa, a live multi-vendor platform connecting farmers and buyers across Nigeria, while building production-ready web and mobile products as a full-stack developer.

I've migrated GreenCart's backend from Node.js to Go and PostgreSQL, improving response times by 75% and reducing memory use by 65%. I also contributed five landed patches to Mozilla Firefox and collaborated on an NHS hospital website using Go, PostgreSQL, Docker, AWS, GitFlow, and CI/CD workflows.
