Hi, I'm Sara, a Barcelona-based Full Stack Developer with a Colombian background. I design scalable web apps using Angular, Node.js, React, Next.js, Ruby on Rails, and TypeScript. I enjoy building robust architectures, APIs, and high-quality frontend experiences. I thrive in collaborative teams, love turning ideas into clean, maintainable code, and I'm always eager to learn new tools like Next.js, TypeScript, and modern deployment workflows. I'm open to opportunities in Barcelona or remotely.
