What I'm looking for

I’m open to remote full-time and contract roles where I can take features from design to deployment independently, build scalable React/Next.js systems, collaborate in async workflows, and work across Web3 and full-stack performance.

I’m a results-driven Frontend / Full-Stack Engineer with 5+ years of experience building scalable web applications across Web3, GIS, CRM, and enterprise domains. I specialize in the React and Next.js ecosystems—architecting component libraries and GraphQL data layers, then integrating EVM-compatible and Tron blockchain protocols into production dApps.

I bring strong ownership and clean, reviewable code focused on scalability and maintainability, plus experience mentoring developers and running code reviews in async, distributed workflows. Most recently, I architected and shipped production dApps at RadianceTeam by integrating EVM-compatible and Tron networks via Solidity smart contracts, building Next.js + TypeScript frontends with GraphQL and Redux/RTK, and developing backend services with NestJS and GraphQL; I also created a reusable component library (MUI, Radix UI, HeroUI) adopted across 3+ projects and reduced new-feature UI development time by ~30%, while integrating Strapi headless CMS and leading a full TypeScript migration.
