## About

I build the backend systems that money moves through: checkout, loyalty, rewards\. My job is to make them boring, meaning reliable, fast, and cheap to run\. Lately, I also build the AI agents and harnesses that help engineer them\. Five years of that at Razorpay, India's largest full\-stack payments company, most recently as Lead SDE\-3 setting technical direction for 10\+ engineers across multiple teams\. The five years before trace the same thread: a messaging gateway scaled from 250 to 2,000 TPS at IMImobile, and billing, order, and payment systems built from scratch at a medical e\-commerce startup\. Some things I am proud of: ★ Pioneered agentic AI engineering on my team: a multi\-agent planning harness that decomposes tech specs into validated, traceable task plans, and 13K\+ lines of agent domain skills with deterministic eval suites\. Used by 25 engineers across 5 projects\. Day\-to\-day: prompt orchestration, tool\-calling, model APIs, evaluation\. ★ Re\-architected Razorpay Standard Checkout's first\-request path into a Go microservice: 17\.5M checkouts a day, 30K requests a minute at peak, 300K\+ merchants, 100% of traffic migrated with zero incidents\. It has absorbed 2x traffic growth since then with no re\-architecture\. ★ Took over a loyalty platform in crisis: money leaks driven to zero, on\-call load from 400\+ tickets a month to about 20, database CPU from 90\-95% down to 20\-25%\. ★ Led "improve catalogue management" from an ambiguous org mandate to a production rewards platform in Go and gRPC, now running card network programmes across a loyalty portfolio whose net revenue has grown close to 4x since November 2024\. ★ Mentored engineers off performance\-improvement plans and into MVP awards, ran 200\+ hiring interviews, wrote a six\-module code\-review curriculum\. Systems only stay boring when the team running them keeps getting better\. How I work: I design systems UNIX\-style, small parts that do one thing well and talk through clean interfaces\. I am most useful in fuzzy environments where the boundaries are not defined yet; that is where the rewards platform came from\. And I still believe coding should be as fun as colouring with crayons or building LEGOs\. Specializations: Go • Distributed Systems • High\-Throughput System Design • Platform Architecture • Agentic AI • LLM Orchestration • Agent Evaluation • Kubernetes • Engineering Leadership Always happy to talk payments infrastructure, Go, agentic AI, or how to make an on\-call rotation quiet\.
