About

Hi, I’m Calogero Sanfilippo, a software engineer from Italy. I currently work as a Software Architect at Gucci.

Outside of work I build open source software, mostly in Swift and Kotlin. On the Swift side, I maintain swift-sgp4, a package for satellite orbit prediction from TLE data, and altai, a small utility for working with Swift typed throws. On the Kotlin side, I’m working on aral, a multiplatform XML push parser built for Kotlin Multiplatform projects.

I also publish a few iOS apps — ISSSeeker tracks the International Space Station in real time, TurinPark helps find parking in Turin, CardStore stores loyalty card barcodes on your phone, and WorldSpinner suggests random travel destinations with a shake.

My CV is available here.
