About Me

I'm a Software Engineer with a passion for building scalable infrastructure and decentralized applications. My expertise spans across the full stack, from crafting responsive frontends with React and Next.js to architecting robust backends with Go, Python, and Rust.

Currently, I'm deeply focused on the Solana ecosystem, building on-chain programs and exploring the frontiers of Web3 technology.
