About

Hi, I’m Sergio Morales Hernández, a full stack developer from Saltillo, Mexico, with hands-on experience building modern, responsive web apps using React, Node.js, SQL, Tailwind, and Sass (BEM). I transitioned from a career in law to tech, bringing strong analytical thinking, structured problem solving, and clear communication to every project. I enjoy designing scalable architectures and collaborating with teammates to deliver robust software solutions.

I’m passionate about clean architecture, UI/UX fundamentals, and delivering meaningful digital products. I love partnering with cross-functional teams to design and implement scalable RESTful services and delightful interfaces, while continuously learning new tools and refining my craft.
