Hello, this Antonis, a Data professional, based in Thessaloniki, Greece. I work in the data analytics industry since January 2019.
I am a Senior Data Analyst at Chubb, a global insurance leader and my mission is to constantly evolve my technical knowledge, shape data mindsets everywhere and inspire people.

From Jan 21’ to Mar 24’I was a co-leader at the Athens Tableau User Group organising interesting Tableau related events, sharing tips for the tool and meeting great people.

The Course I’ve Created: Data Analytics in Modern Corporate Business

To fulfill my mission, I designed the “Data Analytics in Modern Corporate Business” course, available here. This comprehensive program is crafted to provide participants with essential skills and hands-on experience in data analytics within a corporate setting.

Participants engage in a real-world scenario that replicates a corporate data environment. From setting up data pipelines with PostgreSQL and BigQuery to automating ETL tasks with Python and creating dashboards, this simulation ensures hands-on, practical learning.

The main responsibilty of the role was to build models that will lead to actions either for cost saving or revenue increase.
