Today I build an AI-powered identity compliance platform end-to-end. I gather requirements, design the experience, write the code. My title on the org chart says one thing; what I actually do says another — and I stopped trying to explain the difference to HR a while ago. With +14 years of career, I learned that what matters most isn't the role name: it's knowing how to do what needs to be done when it needs to be done. But I didn't get here overnight.
Before all that, I landed at AutenTIC — and it became my home for a long time. There I designed what is now their flagship product: an e-signature and document management solution still in production. "It's like your child", my lead says every time I talk about that product. They're right — and I'm glad it's doing well. I also designed portals for Colombia's National Civil Registry, the Superior Council of Judicature, and the National Mining Agency. Designing for government has zero glamour. It's slow, demanding, and exactly where the craft gets serious. But to get here, I first had to prove to myself I could handle real projects.
Before AutenTIC, the first real projects came in: healthcare service search engines, document management apps for public entities, landing pages for government ministries, city halls, and the Colombian Army. I designed so many things for the government that at some point I lost count — and the will to count them. Along the way, without planning it, I started leading design teams. The weird part was I liked it. Both things: designing and leading. That wasn't in any plan. And all of that started with a project I shouldn't have gotten.
In 2012, I got my first project: designing the screens of a web app for residential complexes in Colombia. Spoiler: I had no idea what I was doing. I'd learned very basic development skills — I was adding inputs and images to screens like a kid playing at building pretty things that didn't work for anyone. To my classmates, I was the best at designing apps. They recommended me with all that confidence. And there I was, facing that project, with no manual and no certainty, with only the conviction that I had to do it. More than 14 years later, that's still the only difference that matters.
