Frontend developer specializing in React and Next.js, building scalable, responsive UIs and integrating APIs with clean, maintainable code.
ThailandWhat I'm looking for
I’m a React Developer and versatile Frontend Developer specializing in React and Next.js, with strong experience in JavaScript, TypeScript, and modern responsive web development. I focus on writing clean, scalable, and maintainable code that delivers strong performance and cross-browser compatibility.
I’ve integrated frontend applications with backend services using PHP (CodeIgniter), RESTful APIs, and Composer-based dependency management, often working in Docker / Docker Compose environments. In cross-functional Agile / Scrum teams, I’ve contributed to high-traffic, scalable web applications and interactive UIcomponents with dynamic animations and advanced visual effects.
I’m also hands-on with UI/UX validation, component optimization, and refactoring for stability and maintainability. I’ve built and modernized products across multiple stacks (React, Next.js, Redux, Redux Toolkit, React Context API, MobX, and parts of Angular), and I use translation management tools like Lokalise and PhraseApp to support multilingual experiences.
