Summary

Senior Frontend Engineer with 10 years of experience specializing in React, Next.js, and TypeScript, building high-performance, scalable web applications. Skilled in designing modern, responsive, and accessible UIs with a strong focus on usability, performance, and maintainability. Experienced in frontend architecture, state management, and design system implementation, collaborating closely with design and product teams to deliver pixel-perfect experiences. While frontend is my primary strength (70% of work), I also bring backend development (Node.js, REST/GraphQL APIs, databases) and testing expertise (Jest, Cypress) to ensure end-to-end reliability and scalability. Adept at working in cloud-native environments (AWS, Docker, Kubernetes) with CI/CD pipelines to accelerate development and deployment. I thrive in cross-functional teams, bridging frontend, backend, and infrastructure to deliver user-centric products that scale to millions of users.
