02 / A LITTLE ABOUT ME

Curious by nature.
Engineer by practice.

THE PERSON BEHIND THE SYSTEMS

I’m a backend engineer with four years of experience building Node.js and TypeScript systems, from payments and digital wallets to AI-powered search and assistants. My work brings together reliable APIs, production observability, and thoughtful technical trade-offs.

I’m currently completing a Master of Information Technology at Miva Open University, specialising in Artificial Intelligence, with expected completion in 2027.

I care about what happens after a product ships: how it handles failure, how it grows, and how easy it is for the next engineer to understand.
