Software Engineer
About
- Hey, I'm Raj — a software engineer with 2+ years building cloud-native systems, AI agent platforms and secure backend services from the ground up.
- I work across the stack, from React interfaces to PostgreSQL and AWS. Lately: RL environments that teach LLM agents to resist prompt injection, and gates that catch what AI-written code gets wrong.
- I care about correctness. Deterministic evaluation, failure modes designed up front, and I review every file my AI tools touch.
