J.O

Frontend engineer and builder, shipping thoughtful products with code and infrastructure.

I am Janet, a Frontend Engineer based in Lagos with 5+ years of experience building high-performance web applications across fintech, enterprise software, and data-driven platforms. I single-handedly architected the frontend for a fintech platform serving 200,000+ users, and I care deeply about the craft of shipping reliable, scalable software.
