about
Hi, I'm Jonathan. I build software from Medellín and make my own apps: I design them, code them and ship them in public.
I build sites for the Web and mobile apps for Android and iOS. AI lets me iterate more, but the judgment is mine.
I think AI is powerful when it's guided well. The value is in iterating, polishing the details and applying human judgment. That's why every pixel and every sentence should feel intentional.
The name
Joblan/jo·blan/
From JOnathan, my first name.
From BLANdón, my last name. The J and the B live in the monogram.
questions

What is Joblan?
MyWalletIt's my personal brand: JOnathan + BLANdón. Everything I build lives here, mostly my own apps like Meld and MyWallet, and the idea is simple: ideas that actually ship.
