About Me

I'm a Lagos-based front-end & full-stack engineer with 5+ years building high-traffic web and mobile apps for the U.S., U.K. and Africa. I cut Largest Contentful Paint 40% for a 120k-MAU PWA, integrated GPT-4o, Gemini 1.5 & Llama 3 into résumé-parsing and chatbot features, and launched headless Shopify stores processing $5k GMV per month. Remote-ready (UTC +1) and obsessed with measurable UX.
