About Christ

Passionate about data and AI, I have been evolving in this ecosystem for over 15 years.
I started my career in data engineering, then moved into reporting and data analysis, BI reporting, and AI. I am now a Data Architect, specializing in AWS Cloud ecosystems. I sometimes wear my project manager hat, particularly for architecture evolution or performance optimization missions.
