Hello, I'm Ryan — software developer

Building forthe web & mobile

Four years turning ideas into fast, thoughtful products — React, React Native, TypeScript and Node.js, tested end-to-end so releases stay calm.

01/ About

Software engineer who cares about the details.

For four years I've been building web and mobile products with React, React Native, TypeScript and Node.js — focused on clean code, honest code reviews and pair programming that makes teams better.

I care about the boring parts that make software feel good: robust end-to-end tests with Cypress and Maestro, and AI-assisted workflows (Claude Code, OpenCode) that let me ship faster without skipping quality.
