What I'm looking for

I'm looking to build and lead production SaaS, marketplace, and payments systems where I can own architecture, delivery, and scalable platform infrastructure.

I'm a senior full-stack engineer who builds the systems that move money reliably, at scale. Over 5+ years I've turned hard problems into production software, usually owning the whole thing: schema, API, interface, and the deploy that puts it live.

My home turf is fintech and multi-tenant platforms escrow, split payments, subscription billing the parts of a product where a rounding error isn't a bug, it's a lost customer. I've built a vetted multi-vendor marketplace with Stripe Connect payouts and escrow, a school-management SaaS I founded and lead as CTO, a freight-logistics platform from an empty repo, and learning systems serving institutions.

My stack is TypeScript and Node on the backend, Next.js and React on the front, Go and PHP where they earn their place, over PostgreSQL, Redis and MongoDB. I care less about the tool than whether it ships something reliable. I work remotely across international teams, I'm available immediately, and I'm building toward the fintech scene across Africa and the Middle East.
