Projekte
- Developed a multithreaded PoC for high-throughput ingestion of Parquet files into a normalized data warehouse using Microsoft Fabric
- Analyzed ingestion performance and identified bottlenecks related to data parsing and pipeline reliability
- Investigated a failure scenario where ingestion silently failed due to parsing issues, leading to empty datasets while queries returned successfully
- Proposed improvements to data validation and error handling to ensure data integrity and prevent false-positive query results
- Designed and implemented backend components and internal services using .NET, MS SQL, and MongoDB
- Built reusable libraries and published internal NuGet packages to standardize development across the team
