Bio

Femi is a senior back-end engineer in TypeScript whose work spans Wander's luxury short-term rentals, fintech payments, and a beauty marketplace. He takes systems from schema design to production: full back ends, payment systems where money never goes missing, and software that runs rental portfolios hands-free. Femi's work is defined by reliability—payouts that complete or reverse automatically, queues that don't drop jobs, and monitoring that pinpoints exactly what broke and where.

...thing I've built is a marketplace payment system where every payout completes fully or reverses automatically—no money goes missing, no human ever intervenes.
