About Me

I build the systems behind useful products

I'm a software engineer who enjoys turning messy product requirements into reliable backend systems, clean APIs, and focused user experiences.

My work often sits around the parts of an app that need careful thinking: authentication, payments, order flows, admin operations, database design, and API contracts that other screens and services depend on.

I care about shipping products that are easy to use, easy to maintain, and strong enough to support real people using them every day.
