8+About
I am a Senior BI/DW Engineer with 9 years of experience in ETL, DWH, and BI development, primarily in the banking sector. I have extensive expertise in building reliable, consistent data warehouses and creating visualizations for performance tracking and financial analysis. My work has involved gathering requirements, system modeling, and developing ETL processes for global banks like Credit Suisse and UBS. I have also been involved in dashboard creation using tools like QlikSense, Tableau, and OBIEE, ensuring that data is presented effectively to drive decision-making. In addition to my technical skills, I have served as a Scrum Master, leading Agile teams through the development process. I have a strong background in relational databases, data modeling, and system architecture. My experience spans multiple tools and technologies such as Oracle, MS SQL Server, Informatica PowerCenter, and AWS. I am a dedicated team player, always eager to learn new technologies and share knowledge with colleagues. My ability to work within Agile Scrum environments and lead teams has further enhanced my capability to deliver efficient and well-structured BI solutions. Outside of work, I enjoy sports, particularly football, and am an avid Real Madrid supporter.Tech Stack
