Professional Summary
Frontend Developer with almost 5 years of commercial experience building and maintaining
websites and web applications. I work with HTML, CSS, SCSS, JavaScript, TypeScript, React, and
Next.js. My experience includes building responsive layouts from Figma designs, developing UI
components, integrating REST APIs and third-party services, working with databases, and
implementing forms and animations. I also handle performance improvements, cross-browser
compatibility, and project deployment. I have worked on both new projects and existing codebases,
fixing bugs, adding features, and improving existing functionality. I enjoy working in a team but can
also handle tasks independently and quickly get up to speed with new technologies.
