What I'm looking for

I want a frontend role where I can build component systems in React/Next.js, optimize performance with clean APIs and data fetching, and use AI tools to accelerate delivery while collaborating closely with UX, backend, and product.

I’m a Senior Frontend Engineer focused on building component-driven, user-friendly web products with React and Next.js. I bring an AI-augmented development mindset—using AI tools and workflow automation to ship AI-driven MVPs and improve delivery speed without sacrificing quality.

In my most recent role, I implemented a component-based approach and a UI Kit (Tailwind CSS / Storybook) from Figma designs, accelerating feature launches by 25% and ensuring 100% cross-browser compatibility. I also helped integrate REST API / GraphQL with the frontend, cutting unnecessary network requests by 40% and improving client-side data loading by 1.5 seconds, while collaborating closely with backend and UX/UI teams.

Previously, I operated as a Middle Frontend Engineer and Junior Full Stack Engineer, creating and improving web apps from scratch, supporting existing codebases, and applying unit/integration testing for reliability. I optimized data fetching and the data layer with tools like React Query, Zustand, and GraphQL, reduced scope creep by 20% through clearer technical specifications, and strengthened team execution through agile ceremonies and clean code practices.
