Hi, I'm Jose Trejos
Full Stack Developer specializing in TypeScript, React, and Node.js. I build scalable web applications that help businesses grow.
About Me
I'm a Full-Stack Software Engineer with over 5 years of experience building reliable and scalable web applications. I work across the stack, designing APIs, integrating frontend and backend systems, and deploying cloud-based solutions.
I enjoy turning ideas into practical, well-structured solutions. Whether it's building from scratch or improving an existing system, I focus on writing clean, maintainable code and delivering results through fast, thoughtful iterations.
Outside of work, I stay up to date with emerging technologies like AI and explore how they can be applied to build more efficient, secure, and user-friendly applications.
