Data Extraction and Transformation: Extracting data from various data sources such as databases, Excel files, APIs, or cloud services, and transforming it into a format suitable for analysis and visualization in Power BI.

Data Modeling: Designing and implementing data models within Power BI to support efficient querying and analysis. This may involve creating relationships between tables, defining calculated columns and measures, and optimizing data structures for performance.

Report Development: Creating interactive and visually appealing reports and dashboards in Power BI to present insights and key performance indicators (KPIs) to stakeholders. This includes designing layouts, selecting appropriate visualizations, and configuring interactions between visual elements.

Query Optimization: Writing and optimizing DAX (Data Analysis Expressions) queries to retrieve and manipulate data within Power BI. This may involve optimizing calculations, aggregations, and filtering to improve report performance.

Data Integration: Integrating data from multiple sources into Power BI to create comprehensive and unified views of organizational data. This may involve combining data from disparate systems and ensuring data consistency and integrity.

Data Governance and Security: Implementing data governance policies and security measures within Power BI to ensure data privacy, compliance, and access control. This includes managing user roles and permissions, applying row-level security, and enforcing data protection policies.

Collaboration and Documentation: Collaborating with business users, data analysts, and other stakeholders to understand requirements and gather feedback for iterative report development. Documenting data sources, data models, and report designs to ensure clarity and maintainability.

Performance Monitoring and Optimization: Monitoring the performance of Power BI reports and data models and identifying opportunities for optimization. This may involve troubleshooting performance issues, analyzing query execution plans, and implementing optimizations to improve report responsiveness.
