Looking for a blockchain developer who can build a DeFi protocol the RIGHT
way — audit-ready, gas-optimized, and production-ready from day one?
I'm Aditya Chotaliya — Full-Stack Blockchain Developer and GATE CSE AIR 61
(Top 0.1% in India). I have already built and deployed a complete DeFi yield
protocol (YieldForge) live on Ethereum — 11 smart contracts, 222+ automated
tests, Chainlink oracle integration, and a full Next.js 15 frontend.
You are not hiring someone who "has read about DeFi." You are hiring someone
who has shipped it.
