02 / ABOUT

I'm a backend engineer from Lagos who likes building the parts of software that other software depends on — distributed services, APIs, and the infrastructure underneath them. I work across fintech, decentralized platforms, and developer tooling, in Node.js, TypeScript, Python and Rust.

These days a lot of my time goes into open source: maintaining tooling across the Stellar and Zcash ecosystems, leading an Arbitrum grant project, and ranking among the top 12 contributors to Zingolib. I care about systems that are reliable, observable, and pleasant for the next engineer to work in — a payment pipeline, a smart-contract debugger, or a privacy-focused node.

When I'm not shipping, I'm usually teaching it — I've mentored engineers at NIIT and run workshops on building with AI agents.
