Staff Software Engineer at Proofpoint

Distributed systems, security infrastructure, and agentic AI.

I build large-scale security platforms and high-throughput backends and I'm going deep on agentic AI — systems that take real actions through tools, not just chat. The twin on the right answers only from what I've actually shared and it says so plainly when it doesn't know.

About

Portrait of Sridhar Chilukuri

I'm a Staff Software Engineer based in Erie, Colorado, with over 12 years in software engineering. Most of my career has been distributed backend and security infrastructure — systems that process huge volumes of data reliably and cheaply. I'd rather solve a problem simply than over-engineer it. Right now I'm focused on agentic AI engineering: building AI that acts through tools, where distributed-systems thinking meets AI.
