About the person behind the notebook
Software engineer in Barcelona. I build the AI platforms and agents other engineers depend on — and an idea only becomes mine once I've made it run.
A little context
I'm Víctor Busqué, a software engineer in Barcelona. For the last eight years I've worked on NLP and generative AI in production — LLM gateways, agent runtimes, and platforms that hundreds of engineers open every morning.
I'm an avid visual learner. I love reading, and I do plenty of it — but an idea stays foreign until I can see it move. A simulation, a figure running the real process, an animation that shows the thing clearly: that's when it clicks.
Reading is usually where the investigation starts. It isn't where it ends.
FOLLOW THE LOGIC
FIND THE STRUCTURE
MAKE THE MODEL REAL
Closer to the systems underneath the product. Closer to the machinery that has to keep working when real people depend on it.
The eight years started here — language systems in production, where a model has to work on Monday morning, not just in a demo.
When generative AI landed, I moved to building with it end to end: prompts became products, and evaluation became engineering.
The work became infrastructure — an LLM gateway and agent runtime that hundreds of engineers depend on: their defaults, their guardrails, their on-call nights.
Today, at a NASDAQ-listed fintech born in Uruguay: agents automating real work — where scalability, robustness and security aren't optional.
Scale is the honest part of the story. Once a system gets large enough, architectural decisions stop being diagrams and start becoming consequences.
The whole site in one sentence
That's probably the simplest description of how I learn. I don't really trust an explanation until I can construct some version of the thing myself and watch what happens. Understanding is something I like to earn.

Everything published here is that loop, left running in public. One idea per post, told as a visual story — because a page that moves is the form I understand best.
Engineering is the core. Curiosity sets the edges. If a subject deserves a slow walk, it can become a post.
