I'm a technical lead on the team that builds and runs the issuance infrastructure for regulated stablecoins carrying more than $4B in on-chain supply: mint and burn pipelines, supply controllers, and reserve operations.

I led the smart contract work for the stablecoin platform, brought Arbitrum and Optimism into the custody platform, and look after the infrastructure powering WBTC.

What I work on

Area
Stablecoin issuance architecture Mint and burn pipelines, supply controllers, and the authorization boundaries between issuer, minter and reserve roles. Regulated tokens need to be pausable, freezable and auditable without becoming unusable.
Multi-chain token operations The same token on four chains. Every one of them has a different account model and a different idea of what freezing an address means, which makes supply reconciliation the interesting part.
MPC custody Threshold signing protocol support in a production custody platform, plus the EVM compatibility work that goes with adding new chains.
WBTC infrastructure Keeping the systems behind WBTC running.

Day to day: Node.js, Solidity, Go, Kubernetes, Postgres, AWS.

Open source

Nautilus Wallet Desktop wallet for the Helix Network, packaged for Linux, Windows and macOS. I worked on multi-chain support and the price ticker.

Pendulum SDK SDK for the Helix blockchain, which forked from IOTA. Protocol enhancements and some of the core research.

Earlier I was a lead engineer at NetObjex, building blockchain applications for enterprise customers and running distributed teams across time zones.

Writing and speaking

I speak about stablecoin infrastructure and regulated token architecture: what compliance requirements actually force into your contract design, and how issuance systems hold up in production. I've given blockchain talks and technical sessions at national-level events in India, and I enjoy teaching this material.

Two older explainers, still the clearest things I've written for newcomers:


Currently curious about AI-assisted engineering workflows, agentic systems and running LLMs locally. Outside work: swimming, community building, and talking people into learning this stuff.
