Somewhere
between logic
and a little
magic
I build software. I think in systems.
And I leave room for a little play.
A small experiment, waiting for you.
Good software starts
with understanding.
Hi, I’m Leon. I’m a software engineer who connects the product, technical, and business sides of an idea.
I do my best work close to both the product and the code. That’s where I can spot tradeoffs early, simplify workflows, and turn a good idea into something people actually use.
I care about solving a real problem and building something that stays useful as it grows.
Many moving parts.
One considered whole.

React / Next.js / TypeScriptFrom system architecture and APIs to deployment, environments, and monitoring, I build the foundations that keep software reliable and ready to grow.
AWS Cloud / System architectureEngineering, usability, and business context belong in the same conversation. I bring them together to build solutions that are clear, effective, and useful.

A fun side project I built in 2017. A small idea that found its way into a lot of people’s everyday lives.
