Senior Nodejs Engineer

I’m a Senior Software Developer with strong expertise in Node.js, React.js, and Blockchain technologies, specializing in smart contract development using Solidity.
I have extensive experience designing scalable backend systems and decentralized applications (dApps), with a focus on building secure, efficient, and future-ready solutions.

I have a proven track record of delivering high-quality code and collaborating effectively within remote, cross-functional teams. My work bridges traditional web systems and the blockchain ecosystem, ensuring reliability and innovation in every project.

Recently, I’ve been actively exploring and building Solidity projects through my repository Solidity Foundations (https://gitlab.com/wsblockchain/solidity-foundations), where I experiment with smart contract patterns, testing, and best practices for Ethereum-based applications.

I’m currently seeking remote opportunities where I can contribute to innovative Web3, blockchain integration, and full-stack development projects, bringing both technical depth and creative problem-solving to the team.
