I build Ethereum clients, DeFi infrastructure, and blockchain analytics systems.

I've contributed to Nethermind's Ethereum execution client, fixing client-parity issues and implementing JSON-RPC features including block overrides, fork overrides, and streaming support.

At Anthias Labs, I built Python routing logic and custom indexers for Uniswap V2/V3, Kittenswap, and Hyperswap, delivering optimized routes in under two seconds. I also maintained AWS infrastructure for HyperEVM nodes, backend services, indexers, serverless functions, and DynamoDB.

My open-source work includes DefiLlama dimension adapters that added fees, revenue, and volume metrics across 20+ protocols and chains using on-chain events, Allium, Dune, GraphQL, and subgraphs.

I'm also building Ethereum tooling and protocols in Rust, Go, Python, Solidity, and Huff—from an EVM implementation in Go to light-client checkpoint utilities, Merkle-proof verification, and zero-knowledge-proof integrations. As President of BlocSoc IIT Roorkee, I lead hackathons, lectures, and blockchain-focused initiatives.
