01 — About

About Me

I work primarily with React, TypeScript, and Next.js. I also have experience with AI prompting, context, and shipping LLM workflows in a real UI.

I contribute to open source, including WordPress and WooCommerce Core Contributor (opens in a new tab), with plugins used by millions.

When I'm not coding, I'm at the gym.

TypeScript

Typed React apps I can still reason about months later, not just pages that compile.

Shipped

Next.js apps with CI/CD and live demos, not mockups that stop at localhost.

AI Product

LLM workflows in a real UI, with OpenAI and LangChain.

Open Source

WordPress Core Contributor (opens in a new tab). Plugins used by millions, including time at Automattic.
