Hi, I'm

Juan Lopez.
Systems Engineering Student & Software Developer

I build web applications and software solutions, with a special interest in artificial intelligence, backend development, and cloud technologies.

About me

I'm a Systems Engineering student at Universidad del Valle, interested in software development, artificial intelligence, and building applications that solve real problems.

I've worked on academic and personal projects using technologies like TypeScript, React, Angular, Node.js, Python, FastAPI, PostgreSQL, Docker, and AWS. I'm currently also exploring generative AI applications and RAG-based systems.

I enjoy learning new technologies by building projects and following good practices in architecture, testing, automation, and deployment.
