I am an experienced Frontend Developer specializing in React, Web3, and DeFi.
What I'm looking for
I am a Senior Frontend Developer with a strong focus on building high-quality Web2 and Web3 products for DeFi and NFT marketplaces. I bring over five years of hands-on experience delivering production-ready user interfaces and developer-friendly frontend architectures.
I have led frontend architecture and feature development using React, Next.js, TypeScript, Tailwind CSS, and advanced state and server-state tools like Zustand and TanStack Query. I prioritize performance, accessibility, and maintainability, applying code-splitting, memoization, and CI/CD practices to improve load times and reliability.
I collaborate closely with backend and smart-contract teams, integrating Ethers.js, wagmi, Subgraphs, and various smart contracts to deliver seamless on-chain experiences. I have implemented testing strategies (Jest, React Testing Library), automated pipelines, pre-commit hooks, and linting to ensure consistency and high code quality across teams.
I am passionate about blockchain innovation and DeFi, mentoring peers and driving best practices while building intuitive, scalable user interfaces. I seek roles where I can continue to push frontend excellence and ship products that make complex financial and on-chain flows simple for users.
