Full Stack Smart Contract Engineer - Ethereum / Solidity / DeFi / NFTs
Full Stack Smart Contract Engineer - Ethereum / Solidity / DeFi / NFTs

Software Engineer experienced in building & architecting decentralized applications on the Ethereum blockchain and Solidity smart contract development. I'm passionate about the future of blockchain technology, ecosystems, and more broadly decentralized technologies.

How I can help you:
1️⃣ Architect, spec, develop, and audit smart contracts.
2️⃣ Build decentralized applications (dApps) with modern frontend technologies.
3️⃣ Consult and advise on the latest topics within the decentralized technologies ecosystem. I can help you flesh out your use cases - without the jargon.

In addition, I can help you:
👉Conduct technical assessment of blockchain protocols and platforms as part of venture building and investing efforts
👉Identify emerging technology trends in the blockchain space
👉Engage with and contributing to the wider blockchain community

What I do:
✅ I've built and launched full-stack dApps with smart contracts on the backend and React.js on the frontend. The projects I worked on have launched on the mainnet.
✅ I'm proficient in smart contract security best practices; I have worked with external security auditors to audit projects. You will get highly secure, resilient, well-tested, and well-documented code.
✅ I'm experienced with Ethereum development tools (Solidity, Truffle, Ganache, Drizzle, web3.js, Infura, Metamask, etc.) You will get projects that follow the latest best practices and easy to test locally.
✅ I stay up-to-date with community projects and research in this rapidly changing ecosystem, such as various Ethereum EIP/ERC proposals. I can help you create your ERC20 / ERC721 tokens, and explain industry standards around decentralized identity, security tokens, and more.
✅ Self-starter and independent learner who can work with minimal supervision. I learn new facts and concepts quickly.
✅ Great at explaining complex concepts in simple terms to a non-technical audience. I communicate efficiently and teach others latest smart contract best practices on my personal blog (yos.io.)

My background:
I'm a full stack developer with 6+ years of experience building web applications for consultancies, tech giants, and startups. I've authored two programming books and launched my own software products from the ground up.
