About me

Greetings! I’m a software engineer focused on web and mobile development, which is now where I do most of my work. I enjoy digging into the business and customer needs behind a project. I ask the right questions to find the real use case, then design a solution from there, instead of just building the first approach that’s suggested.

Outside of that, I’m curious about Machine Learning and AI, and I keep learning across computer science because I believe in steady personal and professional growth.

I’m also a human being trying to leave the world as I found it, if not better. When I’m not coding, you’ll find me running 🏃, snowboarding 🏂 or playing soccer ⚽.
