About
I’m Sunil Kumar Chavhan — a Full-Stack & Blockchain Polymath who loves building systems that scale, ship fast, and break limits. I work across the entire stack: TypeScript, Next.js, Node.js, and cloud-native infrastructure, while also crafting secure on-chain solutions using Solana, Rust, and Solidity.
I've been a 5x Hackathon Winner and Top 4 Solana Hackathon Finalist, selected as one of only 72 fellows from 3,000 applicants, and part of the GitHub Campus Expert Summer 2025 cohort. I thrive at the intersection of Web2 × Web3—where real-time systems, microservices, and decentralized architectures meet.
