about me

root@sameer:~$

I'm a self-taught developer and cybersecurity student from Mumbai with a B.Com background who crossed over into tech through sheer obsession. I build things that matter — flash loan arbitrage bots, smart contracts, security tools, and web apps.

My path: CCNA → CEH → OSCP → CISSP → OSEE. Not just collecting certs — building real-world skills at every step. I believe in learning by doing and breaking things to understand them.

On the dev side, I work with JavaScript, Node.js, Rust, and Solana's Anchor framework. On the security side, I'm building expertise in network analysis, penetration testing, and smart contract auditing.

When I'm not studying or building, I'm researching MEV strategies, blockchain mechanics, and how systems fail at scale.
