I'm Antonio, a 20-year-old CS student writing software for a living since high school. I build products, document the climb, and ship things from a Croatian dorm room.
"You don't escape feeling lost by waiting for clarity. You build your way out."
This profile is the working version of that idea.

The content side. Short form on IG, and YouTube. Long form on YouTube. Documenting the climb from dorm to a real life, one post at a time.

+ Owning what you build is the leverage of this decade.
+ The path out of feeling lost is action, not clarity.
+ Ship rough. Iterate in public. Edit later.
- Waiting for the perfect idea.
- Optimizing for credentials over evidence.
- Pretending to know things you haven't built.A few rules I keep coming back to:
- Build the thing before you talk about the thing. Receipts beat opinions.
- Documentation is the second half of the work. A README is a feature.
- Boring is a feature. Most production code should be the obvious version.
- AI is a tool, not a teammate. It accelerates judgment; it doesn't replace it.
Building quietly. Posting openly. Climbing in public.
