Rafael DeJesus

I'm a full stack engineer with 8 years building software. From internal tools at SAP to co-founding an ed-tech program and an AI startup. At SAP, my work helped save 21,000+ hours in triage time, shipping with <10 minute deploy cycles.

Currently prototyping at the edge of what's possible with LLMs: MCP servers, agent-driven testing tools, and platforms for AI-human gameplay. I thrive in ambiguity and ship to learn.

Open to roles where I can build AI products that matter. LinkedIn ↗
