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.

Expertise

Where I go deep, and what I build with.

01

Distributed systems & APIs

Backend services scaled past 100K transactions per second, and a WHOIS API serving millions of daily requests with Redis caching. Set API governance standards across teams.

100K+ tx/s · <100ms
02

Security infrastructure

Tech lead for internet-scale threat detection and a domain takedown platform that automates remediation for enterprise customers.

Thousands of enterprise customers
03

Data pipelines

Real-time, event-driven ingestion of domain, DNS, email and Certificate Transparency signals into a PostgreSQL store that powers company-wide detection.

1B+ records · 10TB+ / day
04

Cloud architecture & cost

Re-architected a detection pipeline onto ECS Fargate with CLIP image embeddings, cutting latency from days to hours while collapsing the AWS bill.

$3.6M → <$500K / yr
05

Technical leadership

Founded and led an org-wide API working group, ran cross-team architecture reviews, and mentored engineers across teams.

4–6 engineering teams
06

Agentic AI

Currently going deep on AI that acts through tools, where distributed-systems thinking meets AI.

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.
