Full Stack Developer
I'm a full-stack developer with about a year of hands-on experience building end-to-end applications — from Figma wireframe to production deployment — using React, Next.js, Node.js, and whatever database the problem calls for.
Over the past year, I've leaned deep into Web3. I write and understand Solidity smart contracts myself, not just plug them in — I've built and deployed contracts with Hardhat, and integrated them into frontend apps using Ethers.js and MetaMask for wallet-based auth and on-chain transactions. My NFT marketplace project (Puff Market) let users mint, list, and trade assets fully on-chain, with contracts I designed and shipped from scratch.
Beyond personal projects, I've delivered two freelance engagements integrating smart contracts into Next.js applications — including building backend systems to index on-chain events, so contract activity stays in sync with the app's data layer in real time. That combination of "can build the contract" and "can wire it cleanly into a real product" is where I spend most of my time now.
On the fullstack side, I've worked across production systems at multiple companies — architecting REST APIs, optimizing database queries (cutting API response times by ~30%), and building real-time and data-heavy interfaces with React and Socket.io.
I'm looking to bring that same full-ownership approach to a Web3 team: someone who can take a product from idea to on-chain reality without needing to hand off pieces along the way.
