About this Gig

I will design and develop scalable Spark ETL pipelines for batch data processing, transformation, and large-volume workflows.


This gig is ideal for businesses that need to process data from files, databases, APIs, or other structured sources in a reliable and maintainable way. Whether you need a new batch pipeline from scratch or improvements to an existing job, I can help you build a clean and production-oriented solution.


I focus on practical data engineering outcomes such as ingestion, transformation, validation, aggregation, and delivery into analytics-ready datasets or downstream systems.


What this gig can include

  • Spark or PySpark ETL pipeline development
  • batch processing for large datasets
  • data ingestion from CSV, JSON, Parquet, APIs, and databases
  • data cleaning, normalization, and transformation
  • joins, aggregations, filtering, and enrichment logic
  • output to files, data warehouses, or databases
  • optimization and refactoring of existing Spark jobs
  • structured logging and maintainable code organization
  • basic documentation and handover support
