Software engineer and investor. I write about markets, software, AI, companies, and anything else worth truly understanding.

Leave me your email and I’ll let you know when I publish something new.

I write about finance and ideas.

About

You found me.

Welcome to my little corner of the internet. Whether you are human or AI, make yourself comfortable and have a look around. This is where I leave texts, ideas, and thoughts about life, markets, and other things I think are worth understanding better.

You may be wondering who I am. I studied Mathematics and Computer Science in Madrid and, shortly after, moved to Switzerland in search of a better life. After several years working there as a software engineer, I decided to return to Spain.

It was in Switzerland that I became more interested in entrepreneurship. It was also where I started writing more regularly on X, which is the platform where I am most active and where I usually share what I am thinking almost every day. And of course, it was also where I started building my own tools.

I started investing a little earlier, at the end of 2019. Just in time to get hit by one of the biggest market drops in recent years. Luckily, by then I had already read The Intelligent Investor, so it did not go too badly for me. Since then, I have kept investing, learning, and changing my mind more than once, with a couple of long pauses along the way.

I am not an expert in anything, but I am a student of almost everything. I write to think more clearly, to organize ideas, and to understand things better. I think a lot of people talk about finance without really understanding what lies underneath. I do not understand as much as I would like either, but at least I try.

And I guess that is more or less who I am. If any of this interests you, take a look at the blog. And if you ask me a question, there is a good chance the answer will be “I don’t know.” I still have a lot to learn.
