What I'm looking for

I seek frontend roles focusing on scalable TypeScript/React architectures, modern toolchains, performance-driven products, and collaborative Agile teams that value maintainability and continuous improvement.

I am a Frontend Developer with 6+ years building responsive, cross-browser SPA, SSR, and widget solutions for e-commerce, retail, and e-learning. I focus on TypeScript + React + Redux + REST API stacks, and I prioritize user experience, maintainability, scalability, and code quality.

I have led migrations to modern toolchains (Vite, Redux Toolkit, RTK Query), improved performance (Next.js migrations with 50% performance gains), and delivered reusable components and widgets (Svelte widgets, admin dashboards). I contribute to CI/CD improvements and architectural patterns like Feature-Sliced Design to streamline development and long-term upkeep.
