I am a Frontend Developer with hands-on experience building responsive, user-friendly web applications with React, Next.js, TypeScript, JavaScript ES6+, HTML5, and CSS3.

I build reusable components, dynamic pages, forms with validation, API-connected features, search, filtering, pagination, localStorage functionality, state management, and clean UI structure. I also work with Next.js App Router, authentication, Server Actions, PostgreSQL-backed data, loading states, error handling, Git, GitHub, and Vercel deployment.

My QA/QC background helps me create user-focused and quality-driven frontend solutions with attention to usability, requirements, edge cases, bugs, validation, and product quality.

My advantage is a modern technology stack, fresh and up-to-date knowledge, the ability to work with documentation, build interfaces from scratch, and view the product from the user’s perspective.

I am open to Frontend Developer, React Developer, JavaScript Developer, and Next.js Developer roles.
