Rafael Dejesus

I'm a full stack engineer with 8 years experience building software, from internal tools at SAP to co-founding an ed-tech program and an AI startup. I love experimenting with new technologies and pushing the boundaries of what's possible.

Currently prototyping with LLMs: MCP servers, agent-driven testing tools, and platforms for AI-human gameplay.

Looking for roles where I can build AI products for a better future. LinkedIn ↗
