About

I've spent ~9 years building React, React Native and TypeScript apps, mostly in fintech, payments and logistics: consumer payments at Interswitch (Quickteller), proptech in Lagos, voice-based social at Andela, and now regulatory technology out of Dubai.

For the last four years I've worked as a contract senior engineer on two products in parallel: a regulatory platform used by central banks, where I lead the frontend, and a North American freight platform, where I'm the primary developer on the customer-onboarding product and a core contributor across the wider platform.

Alongside client work I ship and run two small SaaS products of my own — TokenWiser (AI spend tracking) and Dev Weekly Digest (automated engineering reporting) — which keep me close to the whole product loop, from billing and onboarding to support. I'm based in Dubai, licensed as a freelancer in the UAE, and available for web and mobile projects.

Where I lean on AI heavily, where I refuse to, and why the line sits where being silently wrong costs more than being slow — notes from building a CBDC platform used by central banks.
