Senior Full-Stack Engineer · Next.js · React · Node.js · TypeScript

I build production-grade SaaS platforms and mobile products — the kind that serve tens of thousands of users without falling over.

7 years in. Shipped across West Africa, Europe, and Canada. Currently based in London, ON.


About Me

I'm a full-stack engineer with 7+ years building end-to-end products — from real-time fintech dashboards to AI-powered SaaS tools. My core is React and Next.js on the frontend, Node.js and PostgreSQL on the backend, with mobile work in Flutter when the project calls for it.

I do my best work in cross-functional teams where the engineering bar is high and the product actually matters to the people using it. I've led teams, mentored junior devs, and shipped entire product lines from zero — not just features inside someone else's architecture.

Most recently at Tapaar Sarl, I led frontend development on a multi-product digital services platform with 50,000+ active users, integrating AI tools (OpenAI, Gemini) and keeping uptime at 99.9%.
