Engineering Lead at BitGo
Stablecoins, custody, smart contracts, and multi-chain systems
Bengaluru, India

Website LinkedIn Twitter Email


I’m an engineering lead at BitGo. I lead the APAC team working on issuance infrastructure for regulated stablecoins, with more than $4B in on-chain supply. That includes mint and burn pipelines, supply controls, and the systems around reserve operations.

I still spend plenty of time in the technical details. I led the smart contract work for a stablecoin platform, brought Arbitrum and Optimism into a custody platform, and have worked on the infrastructure behind WBTC.

What I work on

  • Stablecoin issuance: mint and burn flows, supply controllers, and authorization between issuer, minter, and reserve roles.
  • Multi-chain operations across EVM, Solana, Tron, and Aptos. The same token behaves differently on each network, which makes reconciliation and policy enforcement interesting.
  • MPC custody and the EVM compatibility work needed to add new chains.
  • Infrastructure that supports WBTC.

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

Before BitGo, I was a lead engineer at NetObjex, building blockchain applications for enterprise customers and working with distributed teams across time zones.

Writing and speaking

I speak about stablecoin infrastructure and regulated token architecture: what compliance requirements mean for contract design, and how issuance systems behave in production. I’ve given blockchain talks and technical sessions at events in India, and I enjoy teaching this stuff.

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.
