Hi! I’m a Frontend Developer with nearly 5 years of commercial experience.
I work mainly with HTML, CSS, JavaScript, React and TypeScript. I build responsive websites, turn Figma designs into working interfaces, create reusable components, integrate APIs, and fix frontend issues.
I’m comfortable working with existing projects and handling smaller tasks, from fixing layouts and improving responsiveness to adding features.
I focus on clean, practical solutions that work well across different screen sizes and browsers.
