- Universal InvestmentProcess Reporting Solutions and Software Implementation in Asset Management and Fund EnvironmentBANKING AND INSURANCEJune 2024 - November 2024 (5 months)Frankfurt am Main, GermanyIn my last position, I developed and implemented customized solutions for the automation and optimization of reporting processes, with a particular focus on ESG reporting and data quality. My goal was to reduce manual processes and create innovative reporting products using Python, Power BI, Power Query, Oracle APEX, and Oracle DB. This included developing a real-time updated Power BI dashboard as an early warning system that directly links data quality issues with the data warehouse (Oracle DB). This allowed the tax and reporting team to immediately identify and proactively resolve problems with data providers.Furthermore, I designed a comprehensive ESG reporting tool for the assessment and calculation of MSCI ESG data at fund and issuer level, which meets the regulatory requirements (e.g., SFDR Articles 8 & 9) for clients in wealth management. These solutions led to a significant improvement in data quality, efficient compliance with regulatory requirements, and sustainable optimization of the reporting process.
