About me
I'm Julián, a Senior Flutter Developer based in Colombia with 6+ years building mobile apps for startups and companies across the Americas.
I specialize in Clean Architecture, BLoC state management, and production-grade Flutter development. I've worked remotely with teams in Chile, Ecuador, México, and the US — so I know how to communicate clearly and deliver on time.
If you want an app built to last, not just to demo — let's talk.
