Educational Sabbatical (Study Leave) - Finally taking the time to learn what work always pushed aside. ‣ Intensive Spanish studies (aiming for B1 proficiency, enhancing intercultural competence) ‣ Expanding expertise in modern Data & AI technologies (LLMs, Generative AI, Databricks, Machine Learning fundamentals) ‣ Practical application through a pro bono project in Data Science / Machine Learning ‣ Building personal brand and preparing for next step into independent consulting

Design and lead development of an internal data ingestion framework for the A1 Data Platform (Cloudera, Azure Synapse, Teradata DWH). This strategic tool replaced the existing ETL/ELT processes and handles loading for both the data lake and the DWH, ensuring unified and scalable data integration. The core principle: “Easy data staging by specification, not implementation.” The data engineer or scientist only specifies the source, basic transformations, and target platform.
