About

Physicist &
software developer.

I'm Néstor, a physicist and full-stack developer with 9 years of experience in the nuclear industry. I build things for the web, from simple scripts to SaaS products.

I care about the whole product: from the architecture behind it, to the interface the user interacts with, and being able to explain it clearly to anyone.

How I got here

I studied Physics at the University of Salamanca because I wanted to understand how the world works. Among all the paths that degree opens up, I ended up specialising in nuclear technology.

I moved to Madrid to study the Master's in Nuclear Science and Technology at the Universidad Politécnica de Madrid, where I also completed my thesis.

What I work on

In 2017 I joined Enusa, the company that manufactures the nuclear fuel used by Spanish and several European power plants. I've spent years developing and maintaining the applications that support that process — production, traceability, licensing — in an environment where quality is not optional.

I'm also available for freelance projects. I work best with early-stage products that need someone who can understand the problem and build the right solution.

Why I write

I write because it's the most effective way to learn. If you can't explain something clearly, you haven't really understood it.

Everything on this site is written by me, with no SEO filler. Only things I think are worth reading.
