ABOUT ME

Who am I?

Jose Elias Diaz Marin - Software Engineer profile picture

I'm Jose, a software engineer, and one thing matters to me above the rest: that whatever I build ends up serving someone. It is not enough for the code to compile; I want the person on the other side to understand the interface without effort, the system to hold up, and the solution to hit a real problem. The rest is secondary.

That idea is not just theory. I built Knowty, an educational platform now used by 100+ high school students, and led the five-person team behind it as its sole developer; there I learned that holding the code and the people together at once demands as much as programming.

Knowty left me with a question: what happens when a student does not know what they are missing? Numa is my attempt to explore it. It helps students understand where they are struggling, what to work on next, and why it matters. I am building it alone, from the learning model down to the database schema. It is still in progress, learning from every person who uses it.

I move easily across the stack, from React and Next.js on the frontend to Node.js and databases on the back; but the tool is never the most important point. I keep learning every day, convinced that good software is simple by design. It is reliable, it explains itself, and it never forgets who it is for.

I'm currently studying Ingeniería de Sistemas e Informática at Universidad Pontificia Bolivariana in Medellín, Colombia, on the BecaTech+ scholarship.

What drives me

Clean, maintainable code

I write for whoever reads the code after me. What works today must be able to change without any problem

End-to-end thinking

From the smallest UI detail to backend services and data, I like owning the whole picture.

Built for people

Technology should help real people, not impress them. The goal is impact, not complexity.
