About

I love hacking and building products that people love to use. I am the co-author of a patent describing a privacy-preserving AI asset search algorithm & published a top 2% (by citations) research paper. I have also built products at companies like Postman, Yellow.ai and Scapia in the past. I was the lead engineer for Inbox (ticket/chat management system) at yellow.ai where I setup systems to scale traffic from 10k to 100k+ requests/second. I also built out the email ticketing & analytics products from scratch there, and setup processes for testing, documentation & code review to scale the team. At Scapia, I led products to help travellers apply for visa and avail EMI on their travel spends. Currently I am building generative AI solutions in the software security space at P0. In college, I built online games that went viral (1000s of downloads in 2 days) & launched a model space probe at a NASA competition in Texas (ranked 1st in Asia). I was awarded the Chancellor's Special Achiever's award for this. I am also a certified advanced scuba diver and I spend my free time running marathons and traveling.

Excited to share that I’m starting a new role at Cloudflare, joining the ETI India (Emerging Technology & Incubation) team.
I’ll be working on new AI initiatives at the intersection of systems, infrastructure, and applied AI — with the goal of helping build a better, safer, and more open Internet.
I’ll be starting with vibeSDK, a project focused on democratising “vibe coding” and making powerful AI-driven development workflows more accessible to builders.
Grateful for the journey so far, and really excited for what’s ahead. Let’s build. 🌍⚡

Led scrum while actively clearing team blockers, which led to a 40% reduction in time taken to complete shorter tasks.
Individual Contributions
Wrote and deployed a Golang - Postgres micro-service from scratch that enabled CS agents to handle tickets over the email channel (similar to Freshdesk/Zendesk).
Revamped the back-end that handled agent conversations to Node.js MVC architecture and eventually scaled it to handle 80k RPM from 8K RPM over 2 years.
