I am a Senior Full Stack Developer with over 10 years of experience specializing in React, TypeScript, Next.js, and building performant and accessible UI architectures. My skills extend to Vue, Angular, and Svelte as needed, and I focus on creating scalable design systems and microfrontends while optimizing Core Web Vitals with techniques like smart code splitting, caching, and observability. I bridge frontend and backend development with clean API designs using GraphQL, REST, WebSockets, and tRPC, and have backend experience with Node.js, FastAPI, Django, and Go microservices. I mentor teams, enforce testing and accessibility standards, and deliver fast, secure, maintainable user experiences aligned to product goals.
