5 years of frontend expertise. Building high-performance DeFi protocols on Solana From $20M TVL DeFi products to enterprise-grade web applications.
Building the Decentralized Future
I'm a frontend developer with 5 years of experience, including deep specialization in Web3 DApp development. As a core developer, I've built Solana ecosystem projects that reached $20M TVL.
My expertise spans Solana & EVM smart contract integration, wallet connections, transaction signing, and frontend performance optimization. I have deep understanding of DeFi protocols including AMM and DLMM mechanisms.
Beyond Web3, I've led frontend architecture redesigns, built enterprise-grade applications, and implemented complex systems including SSO authenticationand multi-role permission management. Proficient in AI-assisted development tools (Cursor / Claude Code), boosting productivity by 2-3x.
