STORY
A little bit about myself.
I'm a software engineer from Colombia with five years of experience building mobile apps. I started with Android, and my first app opened the door to the industry. Today I work across Android, iOS with SwiftUI and Kotlin Multiplatform, and at Sistecrédito I help maintain an app used by more than 100K people.
I'm self-taught and curious by nature, and that curiosity led me to build DragBuilder: an AI app builder where anyone can describe an app and refine it by dragging, no code required. I designed and developed it on my own, and it launched in October 2026. I also maintain open-source libraries for Kotlin Multiplatform, like AWS-KMP and KaptureX.
I learn by building. Every day I try to pick up something new and set goals that force me to improve, which keeps me current with the latest technology and pushes me toward solutions that go beyond the conventional.
