I offer a wide range of services in Business Intelligence – everything from specific tasks to ongoing collaborations. Below you will find an overview of what I can help you with.
SQL Optimization
Slow queries, inefficient data models, and oversaturated databases cost time and money. I analyze your SQL codebase, identify bottlenecks, and optimize queries, indexes, and database structures for better performance and stability.
Data Analysis
Transform your raw data into understandable insights. I conduct exploratory analyses, pattern recognition, and statistical evaluations tailored to your business's questions.
Reporting
Build report structures and dashboards that provide decision-makers with the right information at the right time. Tools: Power BI, Tableau, Looker, SQL Reporting Services, Excel – or whatever you already use.
Data Visualization
Data that is visualized correctly is data that is used. I design clear, understandable, and action-oriented visualizations that support your decision-making process.
Data Strategy
Do you lack a clear plan for how data should be collected, stored, and used? I help you develop a data-driven strategy adapted to your goals, your organization, and your level of maturity.
Training and Knowledge Transfer
Do you want to strengthen your internal team? I offer workshops and training in SQL, BI tools, and data-analytical thinking.
