Graham Hagenah

I’m a full-stack web developer and designer with seven years of experience building fast, accessible websites and applications, from the interface people see to the APIs and databases behind them. I work mainly in React and TypeScript, and in WordPress when a client needs a content management system.

Open to workBased in Somerville, MA, and looking for web development and design roles in Boston or beyond.

Projects

Noteworthy projects I’ve built on my own time, from 2021 to 2026. Most are written in React and TypeScript, with Remix for full-stack apps, Python for gathering data, browser APIs for sound and speech, and GitHub Actions and Pages to build and host them.
