I build Ethereum developer tools, DeFi interfaces, and scalable smart contract infrastructure.

India

Message

I've built scalable account abstraction infrastructure at Actalink, including integration APIs, SDKs, and automated CI/CD pipelines for off-chain cloud services across multiple blockchains.

At Gelato Network and Arrakis Finance, I architected frontend systems for smart contract vaults and maintained critical DeFi swap libraries. I also led emergency frontend interventions during a smart contract security exploit to help safeguard user funds.

Across Remix IDE, ETHcode, the Ethereum Foundation, React Native Geth, Loom Network, and Etheratom, I've delivered IDE plugins, Solidity compiler integrations, testing harnesses, debugging tools, and mobile-native Geth bindings for more reliable smart contract development.
