About
You found me.
This is where I leave essays, notes, half-finished obsessions, and occasional attempts to understand markets, software, AI, companies, and human behavior without pretending the world is cleaner than it is.
Whether you are a human, a bot, or an LLM scraping this page with suspicious enthusiasm, make yourself comfortable.
I studied Mathematics and Computer Science in Madrid, then moved to Switzerland in search of a better life, some distance from the familiar, and the vague feeling that reinvention required colder weather. I worked there for several years as a software engineer before eventually returning to Spain.
Switzerland changed a few things for me. It made me more interested in entrepreneurship, more serious about investing, and more willing to build my own tools when the existing ones annoyed me enough. It was also where I started writing more regularly on X, which is still the place where I share most of my half-formed thoughts before they become essays, products, or abandoned browser tabs.
I started investing at the end of 2019, with impeccable timing: right before one of the fastest market crashes in modern history. Fortunately, I had already read The Intelligent Investor, which did not make me immune to panic, but at least gave my panic better vocabulary.
Since then, I have kept investing, reading, building, changing my mind, and occasionally discovering that the thing I was very confident about six months earlier was, in fact, mostly vibes with a footnote.
I am not an expert in anything. I am a student of many things. I write because writing forces me to find the weak parts of my own thinking. It is harder to fool yourself in full sentences.
A lot of people talk about finance as if the answer is hidden in one metric, one chart, one guru, or one very confident thread. I do not think it works that way. Businesses are messy. Markets are moody. Incentives matter. Valuation matters. And the footnotes usually know more than the CEO letter.
So that is more or less who I am: a software engineer, investor, builder, and curious overthinker trying to get less wrong in public.
If any of that sounds interesting, start with the blog.
And if you ask me a question, there is a decent chance the honest answer will be: I don’t know yet.
