Engineer by trade.
Problem solver
by nature.

I’m a full stack developer who’s most at home turning complicated requirements into products that feel straightforward to use and maintain.

My recent work has focused on modern React and TypeScript front ends for SaaS and enterprise platforms—without losing sight of the APIs, data models and deployment pipelines behind them.
