Question 1

Who is Ketan Chavan?

Accepted Answer

Full-stack engineer with 2.5+ years building production systems at Reliance Jio that serve over 100,000 users daily. I started in frontend — React, Next.js, TypeScript — and gradually owned more of the stack: APIs, caching, deployment, observability. The pattern holds across every project I've touched: understanding how the whole system fits together makes the individual parts better.

Question 2

What does Ketan Chavan build?

Accepted Answer

Right now I'm building fintech infrastructure at JioBlackRock, where I architected a headless CMS platform that lets marketing teams publish pages in under 5 minutes instead of filing tickets. I also built a Redis cache handler that cut P95 latency from 2 seconds to under 200ms. Most of my best work is invisible when it's working — which is how it should be.
