01About
Who I am
I'm a final year undergraduate student at IIT Indore, specializing in blockchain development, smart contract security, DevOps engineering, and backend engineering. I'm an aspiring security researcher.
Currently, I'm diving deep into DeFi mechanics, zero-knowledge systems, formal verification, DevOps, and open-source systems development to strengthen my expertise in security, backend engineering, and production-grade blockchain infrastructure.
