About
Building software that works in the real world.
I'm a Software Engineer who can build software — and who also understands how software gets integrated, deployed, supported, and used by real businesses.
I have 4+ years of experience across backend and frontend engineering, Python and JavaScript, REST APIs, fintech systems, automation, and technical implementation. That includes 25+ client implementations, 23% faster setup, 15% higher client adoption, and a 30% improvement in time-to-value.
I currently work as an Implementation Engineer, combining software engineering with systems integration, UAT, go-live, and production support. Outside of client work I built Apply Pilot to help African job seekers tailor applications and track them without spreadsheets.

A different kind of engineer
Need a Software Engineer who can also ship implementations?
I work across engineering, technical support, and client delivery — translating technical requirements into working systems, troubleshooting production issues, and helping implementations move from requirements to production.
