I'm a backend-focused fullstack blockchain engineer. I build decentralized systems and the infrastructure that makes them usable. Most of my work lives somewhere between cryptography, distributed systems, and developer experience.

Some highlights: won ETHIndia 2024 with zkRail, coauthored ERC-7518 for globally compliant RWA tokenization, built the first ERC-4337 multichain wallet, and developed core infrastructure for EIP-7702 and EIP-2771 meta-transaction relayers.

The Story

I had a turning point at age 11 when I picked up "Head First Programming" from a bookstore. The world wasn't the same anymore. Just layers of abstractions. Physics became an interface to the API of the Fundamental Nature of Reality, one whose implementation I could not take a peek at.

"How does magic work? You wave a wand and say the right words in the right order and you control the physical world. But then you realize there really is something like magic right here: programming." George Hotz

I had found magic in programming. In being able to create so much change with just a couple of keystrokes. I was hooked.

Fast forward 7 years. Professional experience as a freelancer, working with global clients, but still stuck at Kota cramming for IIT-JEE. When COVID lockdowns started, I took it as a blessing in disguise. I had enough of the rat race. I was out.

This felt like the hardest decision I had ever made. It was not easy to convince my very conventional family that their 18-year-old was going on a path so unwonted. But through countless arguments, they reluctantly agreed.

My first full-time opportunity was at a London-based startup building a decentralized censorship-resistant podcasting platform. It was here I truly started to appreciate web3: a world where you don't need to implicitly trust, where actions are transparent, where power belongs to the people. A world built by misfits. A world where I belonged.
