Blockchain and Backend Engineer | Rust · Solana · Node.js · TypeScript

I build blockchain infrastructure and the backend systems around it. My work spans a Token-2022 stablecoin SDK on Solana, a production Node.js webhook processor, a Rust WebSocket engine at 648k msgs/sec, and an EVM indexer handling 10M+ transactions. I write Rust for performance-critical systems and Node.js with TypeScript for everything else. Currently available for remote roles.

About Me

I build blockchain infrastructure and the backend systems around it. On Solana I have shipped a Token-2022 stablecoin SDK with Transfer Hooks and ZK proofs, an on-chain job queue with a native binary max-heap, and a production Helius webhook processor. On EVM I built an indexer handling 10M+ transactions and a Solidity tokenization protocol that won 1st place out of 2,500+ global teams. I also built VatanPay, a live remittance protocol on Stellar using Soroban smart contracts and DEX path payments.

I write Rust for performance-critical systems and on-chain programs, and Node.js with TypeScript for backend services and APIs. Previously I built internal Rust security tooling during my cybersecurity internship at the Prime Minister's Office, Government of India.
