Hi, I'm Sergio
Full-Stack Developer from Costa Rica.
I specialize in building clean, scalable, and user-friendly web apps that enable the success of startups and established enterprises.
About
Since 2018, I've built enterprise SaaS platforms, e-commerce systems, and web applications as a full-stack developer, seamlessly collaborating with cross-functional teams to deliver tailored solutions.
My adaptability and proactive approach allow me to contribute seamlessly across various disciplines—whether it's frontend, backend, devops, or marketing—to drive rapid innovation. I leverage industry best practices by adhering to SOLID principles, creating well-documented components, implementing comprehensive end-to-end testing, maintaining clear documentation, integrating feature flags, and managing advanced CMS architectures.
I work with a production-grade stack including Next.js, TypeScript, Hono, Nest.js, PostgreSQL, Drizzle/Prisma, and AWS to build scalable, reliable solutions.
