The five things I can't stop thinking about.
I'm a software engineer who writes — about software, health, sport, food and life. Five threads that keep turning out to be the same thread. No feeds, no funnels. Just the notebook.
A bit about me
Hello / hola
I build software for a living and can't stop poking at how the rest of life works the same way — in systems, feedback loops, and small habits that compound.
I grew up just outside Barcelona, in l'Hospitalet de Llobregat. By day I'm an engineer; the rest of the time I'm lifting something heavy, cooking something simple, or trying to undo whatever the week did to my sleep. None of it stays in its own lane, so I stopped pretending it did.
This site is where it all goes — one notebook for the code, the training, the food, and the thinking in between. If something here is useful, or wrong, or you just want to say hello, I'm easy to find.
The notebook
- 20 Jun 2026 I keep building my own tools Half my GitHub is just coursework. The other half exists because something didn't fit me and I built the version that did — and after a year of it, that half is most of what I actually do. Software · 3 min
- 20 Jun 2026 Is this food good or not Every nutrition app answers a question my dad never asked. He doesn't want a score to decode. He wants to know if he can eat the thing. Nutrition · 2 min
- 20 Jun 2026 It always comes back to the mountains Software, health, sport, food, life — it looks like five different interests. Look closer and they all point at the same place. Life · 2 min
- 20 Jun 2026 My watch said I slept badly I woke up full of energy and a number told me I was wrong. That's when I stopped trusting training apps and built my own. Sports · 2 min

Building
-
Peak Health — training
A training app that works from how you actually feel, not just your watch's recovery score. Early, but I use it daily.
-
Eat or Skip — nutrition
Tells you whether a food is good or not, in plain words — no score to decode. Built for my dad.
-
materialize — open source
AI coding-agent skills for real engineers — straight from my .claude directory.
-
erikpastor.com — this site
A handmade Astro site where code, training, and life share one notebook instead of five separate feeds.
Say hello
Most of the thinking lands here first. The rest of me is a short list of links — I read everything.
