Ellen Welsh / Senior frontend developer

Frontend engineering,
with a design eye.

I build product interfaces, connected-device experiences and websites with React and TypeScript. My design background shapes the details, and my personal projects explore coding agents, interactive 3D and practical tools.

Agentic programming

Personal projects exploring art direction, working interfaces and agentic programming. I set the design direction, use coding agents to develop the implementation, then refine the details through visual review and feedback. The projects span bespoke wedding websites, practical tools and interactive 3D.
