Jamie Harris

Zero-to-one product builder and non-profit entrepreneur

Hi, I'm Jamie. I'm based in London and I work at the Centre for Effective Altruism, where I build and run programs that help people to do the most good they can, and advise other teams on product strategy and scaling. I have around seven years of background in talent search and community building programmes. I co-founded Animal Advocacy Careers, and I built up Leaf — a nonprofit that helps exceptional teenagers pursue high-impact paths — where I'm now board president.

Outside work, I design board, card, and video games, build useful software tools, and write and perform music.

Courses

Programmes I've built or run to help people maximise their impact.

Tools

Software I've built, mostly with Claude Code. Stacks vary across Next.js, React, Supabase, and Tailwind.

Most of my games are vibe-coded the same way — built with Claude Code. See the section.

Games

Board, card, and digital games I've designed.

Music

I play in hardcore bands; drums in most, bass in Big Smoke, the current one.

Production

Most of my music is hardcore, but I also produce some low-quality, unreleased tracks in UK electronic and urban genres: dubstep, grime, and UK drill.
