Within Construction Chemicals BUs, I designed and delivered a global end‑to‑end data platform capable of ingesting and harmonizing data from all CC legal entities worldwide. More than 25 heterogeneous sources — including SAP, Sage X3, Snowflake, SharePoint drops, MDM systems, and various REST APIs — were integrated through standardized ingestion pipelines. Data was cleaned, transformed, consolidated and modeled to produce Analytics‑Ready Data Marts, supporting both operational and strategic use cases. The platform also feeds Magnitude with critical commercial and master data (Sales, Products, Customers, etc.), ensuring a single source of truth and enabling reliable reporting, forecasting and performance steering. Main developments include : - Synapse/ADF pipeline developments. - SQL (Stored Procedures) and PySpark developments. - Functional requirements gathering. - Project architecture improvments

Within the RISQ/CTL division, I led the industrialization of the bank’s regulatory and operational‑risk reporting data pipelines. I transformed raw data‑lake dumps into high‑quality, governed data assets, enabling consistent, auditable and high‑performance reporting across the group. I designed and optimized Azure Synapse and Data Factory pipelines, built SSAS/AAS cubes and Analytics‑Ready Data Marts, and delivered Power BI applications used daily by regulatory, compliance and operational‑risk teams. This work significantly reduced data preparation time, improved reporting reliability, and accelerated regulatory submission cycles. I also drove performance optimization across the entire analytical chain, improving cube refresh times, stabilizing ingestion workflows, and increasing the scalability of the platform for future regulatory requirements.

Within the RISQ division, I led the modernization of the bank’s regulatory and operational‑risk analytics platform by expanding and industrializing Azure‑based data services while maintaining critical on‑premise SSAS/Report Server assets. I worked closely with business teams to identify regulatory needs, translate them into functional specifications, and design multidimensional data models supporting high‑volume, audit‑ready reporting. I delivered Spark‑SQL ETL pipelines and built Azure Data Factory, Azure Synapse, Azure SQL Database, and Azure Data Lake Gen2 components to migrate and modernize ingestion, transformation and analytical workflows. On the analytical layer, I developed AAS/SSAS OLAP cubes and Power BI dashboards, enabling unified, reliable and faster reporting across risk, finance and compliance. This Azure‑driven modernization reduced manual data preparation, improved reporting reliability, and accelerated regulatory submission cycles, while the hybrid architecture ensured continuity of legacy reporting during the transition.
