About
We developed a scalable, high-performance data platform with a centralized Data Warehouse integrating APIs and SQL Server sources. ETL pipelines powered by Apache Spark enable distributed data processing, while Apache Airflow orchestrates workflows. Using FastAPI for modular endpoints and Pandas for data transformation, the system ensures efficient processing, robust monitoring, and automated recovery for reliability.
Challenge, approach, and impact
Scalability & Performance
Ensuring the platform could efficiently process large datasets while maintaining high-speed performance.
Complex Data Integration
Centralizing data from multiple sources, including APIs and SQL Server, required robust ETL pipelines.
Workflow Orchestration
Managing dependencies and scheduling tasks efficiently with Apache Airflow for seamless automation.
Optimized Query Performance
Implementing SQL Server views, UDFs, and stored procedures for incremental updates and fast data retrieval.
Error Handling & Monitoring
Building a robust logging system to track execution times, errors, and import metrics for reliability and automated recovery.
