Hi there! I'm Gianpaolo Raphael N. Reinar, a web developer based in Stockton, CA. I build full-stack web applications using Next.js, TypeScript, React, and Tailwind CSS. My work emphasizes scalable architectures, RESTful APIs, cloud deployment, and maintainability, with a strong focus on accessibility and user experience. I collaborate in Agile teams, lead projects, and enjoy turning ideas into polished, production-ready features. Beyond coding, I design digital media and promotional materials as a freelance graphic designer, contribute to open-source projects, and mentor teammates through Trello for task management and Git for version control. I’m always eager to learn new tools and craft reliable software that users love.
