A bit about me

Hi, I'm Franco.

At Ergon, I automated model tuning for banking fraud detection, cutting experimentation time by 60%. I also worked on Android inventory apps and backend services. At ZHAW, I researched cloud systems and robotics.

I like building a small tool to understand a problem. I ask for independent reviews, and keep notes so the next person can pick up the work.

Outside work, I'm a volunteer firefighter in Winterthur.
