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.

Launch.Today (No Code Vibe coding platform for production-ready apps) - Built an agentic LLM-based platform from scratch - Prompt engineered multiple parts of the workflow to get optimal results - Built an auto code fixing layer over the generated code to output working apps consistently - Learnt how to grow a consumer AI app from 0-1 and onboard customers P0.inc (static analysis + gen AI based API vulnerability scanner) - Wrote AST parsers and gen AI-based static analysis tools to find vulnerable code in Golang and .NET repositories.

- Built the Visa product from scratch that enabled Scapia customers to apply for travel visas on the app. - Built the async EMI stack for features like TNPL, where users could avail EMI that would be posted on transaction settlement. - Developed an end-to-end mocking framework with a no-code interface, reducing testing time for card onboarding from a day to a few minutes. - Owned and developed the backend for the gamification feature, which increased the % of customers making their first transaction in the first week by 20.

Leadership Initiatives - Supervised and collaborated with new joiners while providing technical direction, which helped grow the back-end engineering team from 3 members to 8 within a year. - Introduced unit testing and linting, and guided teammates in writing better unit tests. This reduced the time to production for minor code changes and made production bugs in older code a rare occurrence. - Developed triage processes that reduced the time taken to solve repeated issues from days to hours, clearing a backlog of 100+ tickets to 0 within 2 weeks. - 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. - Optimised critical API routes, reducing response time by 60%. - Built a Bull queue-based MongoDB - ElasticSearch sync that fixed race conditions and increased reliability. - Built APIs for the analytic dashboard, enabling CS admins to monitor agent performance.

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.
