John Ryan Cottam

I'm a senior full-stack engineer with deep experience at Amazon and Stripe. I've shipped advertising systems and financial infrastructure where reliability and clarity mattered.

Today I build AI-native products: agentic workflows, MCP integrations, and UIs that feel intentional—not bolted on. I write about what I learn on Notes, share open source tools, and maintain Agent Resources for Cursor and Claude Code.
