About Me

Hi, I'm Gustavo, a full-stack web developer focused on building clean, scalable, and accessible web experiences. I work primarily with modern React/Next.js front ends and TypeScript-driven back ends.

I turn high-fidelity designs into production-ready interfaces using Next.js, TypeScript, TailwindCSS, and shadcn/ui, and support full delivery with back-end experience in NestJS, Prisma, FastAPI, and PostgreSQL.

I'm currently a Full-Stack Developer at Rápido Infoshop, building mobile-first UIs, integrating APIs, and collaborating closely with product and engineering teams.

I enjoy turning ideas into real, usable products and continuously improving through new tools, technologies, and patterns.
