Über Mittu

I help businesses turn raw data into actionable insights fast. With 3+ years of experience in building scalable ETL pipelines, designing intuitive dashboards, and optimizing cloud-based data workflows, I bring both technical depth and business clarity to every project.

What sets me apart? A strong foundation in healthcare analytics, hands-on expertise with tools like DBT, Power BI, and Azure Data Factory, and a methodical approach to solving complex data challenges. I’ve worked with global teams, led data migration efforts, and built fraud detection models that saved time and money.

Typical projects I handle:
  • End-to-end data pipeline development (SQL, Python, Azure)
  • BI dashboard creation and reporting automation (Power BI, Excel)
  • Cloud data integration (Snowflake, Azure Synapse)
  • Data modeling and documentation (DBT, ERD tools)
  • Healthcare analytics and compliance reporting
