§ 2About

Maths to Aztec

I came into software from a B.Sc. in Mathematics, self-taught the web, and spent my first two years at Craxinno shipping React and vanilla-JS interfaces for clients. That is where I learned to actually finish and ship things.

Since May 2024 I've been at Cyphronix, going deep on the hardest part of the stack: privacy-preserving blockchains. In a couple of years I went from vanilla JS to writing production apps on Aztec's ZK rollup, integrating Sui Move and Solana Anchor contracts, and publishing a TypeScript SDK to npm.

What I actually enjoy is owning a product from the contract to the cursor: designing the indexer that reconstructs on-chain state, the API that serves it, the SDK other developers build on, and the interface a user actually touches. When a network is missing a piece of infrastructure, I build it rather than wait for it.

Based in Bengaluru. Open to remote and to founding-engineer roles.

2022 to May 2024
- First professional role: built web interfaces for client projects in React and vanilla JavaScript.
- Shipped responsive, production UI to real users and learned the craft of shipping.
