About Me

Web3 Developer specializing in smart contracts, dApps, and decentralized infrastructure

Web3 Developer - Profile

I'm a Web3 Developer specializing in smart contract engineering, decentralized application development, and modern frontend architecture. I build secure, scalable, and elegant experiences across the EVM ecosystem.

My work spans EVM smart contracts, dApps with real-time blockchain interactions, Web3 infrastructure, and decentralized UX design. I enjoy combining strong technical foundations with thoughtful interface design to create smooth and reliable Web3 products.

I believe in clean engineering, predictable workflows, strong security practices, and transparent communication. My approach balances deep technical research with pragmatic execution, ensuring each part of a system is robust and maintainable.

In the Web3 space, I've worked on smart contract systems, minting flows, staking logic, AA/4337 flows, metadata systems, and integrated multiple infrastructures like IPFS, Supabase edge functions, and custom RPC tooling.

I focus on continuous learning, writing better code every day, and contributing to meaningful decentralized technologies.
