Web3 Developer | Solidity, DeFi, Next.js, Security Audit

Hey, I’m Oxel. I’m a Web3 developer specializing in secure smart contract engineering, audit-quality code reviews, and building full-stack decentralized applications. Over the last few years, I’ve focused on the DeFi space, helping protocols move from initial whiteboards to secure, production-ready deployments. What I can help with: Smart Contract Engineering & Architecture : I design and build the core logic of DeFi protocols, including AMMs, lending markets, and yield strategies. I write clean, gas-efficient Solidity code using Foundry and Hardhat. My goal is always the same: create a protocol that is as performant as it is resilient to the "dark forest" of the EVM. Security Reviews & Vulnerability Research : I don’t just build; I also break. I’m an active participant in smart contract security competitions (like Code4rena and Sherlock), where I analyze real-world protocols to find critical vulnerabilities. This "auditor mindset" allows me to anticipate attack vectors like reentrancy, oracle manipulation, and logic errors long before they reach production. Full-Stack dApp Development : I handle the entire lifecycle of a blockchain product. This includes the smart contract design, rigorous testing (fuzzing and invariants), and building the frontend integration using Next.js, TypeScript, and Ethers.js/Viem. I ensure the user experience is as smooth as the on-chain logic is secure. Audit Readiness & Testing : If you have an existing codebase, I can help get it "audit-ready." I’ll clean up the logic, optimize for gas, and set up advanced testing suites to ensure 100% branch coverage and protocol safety, significantly reducing your eventual audit costs and timelines. How I work: I’m a proactive, transparent communicator who believes that in Web3, clarity is safety. I’ll keep you updated on every milestone, explain technical risks in plain English, and offer suggestions on how to improve your protocol's incentive structures or security posture along the way.
