About Me

Ben Crow — cartoon avatar with brown hair on a blue background

Full Stack Engineer at Culture Amp (Nov 2024–present), building features end-to-end in Next.js, TypeScript and Ruby on Rails at scale. I integrate LLMs into development workflows — from AI-powered tooling with MCP servers and Claude Code, to shipping AI features in production. I'm focused on how agentic coding patterns change the way teams build software. A strong communicator and facilitator, I engage effectively with people from a wide range of professional backgrounds and perspectives.

Rails AI 20 Questions

Pixel art sky and grass with login form centered
A Ruby on Rails app built with my wife Niki. Integrates with OpenAI to play 20 questions — the AI thinks of something and responds to yes/no questions until you guess it or run out of turns. Authentication via bcrypt and Rails sessions keeps API usage in check. Containerised with Docker and deployed on Render.
