Software Engineering Meets Web3.

Combining a strong software-development background with blockchain and decentralized application development.

I am a Software Engineer with 9+ years of experience building web and mobile applications, APIs, database-driven systems, integrations and production software.

I am now focused on Blockchain and Web3 development, with an emphasis on Ethereum and EVM-based applications, Solidity smart contracts and full-stack decentralized applications.

My current Web3 development stack includes Solidity, Ethereum, EVM, Foundry, React, TypeScript, Wagmi, Viem, MetaMask and smart-contract integration.

I am particularly interested in building practical DApps where frontend applications interact directly with smart contracts and blockchain networks.
