I didn't start in blockchain. I started with React, Node.js — shipping production apps for EVs, sports streaming, and tourism. Then I built a token launchpad on Solana. Everything changed.

The mindset shift hooked me: write a great contract, deploy it, it runs forever. No servers. No AWS bills. No DevOps at 3am. Users own their data — not a company sitting on a private database. That's how software should work.

Now I go deep on Rust and on-chain engineering — compute unit efficiency, PDA security, account validation, and DeFi primitives that are hard to break. Rust forces you to be honest. No hidden costs, no GC surprises. Just deterministic and fast.

Open to Solana smart contract, DeFi protocol, or on-chain engineering roles.
