Data Architect and Backend Python Developer. Based in Italy. Rides bikes, and has built the timing software for a cycling federation.
About
I am a Senior Data Architect at TAI Solutions in Pisa. My top skills are Databricks, Oracle Cloud and data architecture. Before this I was a data engineer for CENCOSUD, one of the largest retailers in Latin America.
I started on the shop floor programming CNC machines, then moved through a Delphi and Oracle ERP, a CTO role and several Python API teams. That path is why I like systems that touch real hardware and real data.
Away from the screen I ride and take part in cycling events. The two meet in one project: the timing software below.
