The most amazing...
...thing I've implemented was an operation data lake to ingest real-time data from Open Data Hub APIs related to different transport modes.
Work Experience
Senior Data Engineer
Data-Driven AI
- Developed Azure durable entity functions to ingest data from Open Data Hub APIs in case of changes in the response header. The action saved 8GB of storage space every day and reduced costs significantly.
- Built an app in Microsoft Power Apps to fetch the resource usage costs and cost optimization recommendations from Azure subscription. The app helped users monitor resources and reduce costs.
- Created a self-service API and Microsoft power app for business users to securely download historical GTFS data on-demand from a data lake without manual intervention. The action saved 40 hours of manual effort every month.
- Built data pipelines using Azure Databricks (Pyspark) to process the ingested data into the Delta lake and the Synapse data warehouse.
- Created streaming data pipelines using Databricks to ingest data from Event Hub and Cosmos DB.
