# About Me

I'm a software developer with nearly 3 years of experience, specializing in Blockchain and Web3 for over 2 years. My expertise spans the Solana ecosystem and EVM-based blockchains. I build decentralized applications using Rust, Solidity, and TypeScript, and develop robust back-end services with Rust (Axum, Tokio). I am passionate about DeFi protocols, NFT mechanics, and building secure, scalable on-chain solutions.
