  • Expert-level proficiency in Apache Spark (PySpark), including Spark RDDs, DataFrames, Spark SQL, and deep understanding of Spark internals (e.g., execution plans, DAGs, memory management).
  • Proven experience designing and implementing large-scale, high-throughput Spark-based ingestion pipelines, using both custom and standard data integration patterns.
  • Strong hands-on experience with ETL/ELT pipelines and data warehousing concepts.
  • Advanced Python programming skills, particularly in data processing with PySpark and Pandas.
  • Practical experience identifying and resolving Spark performance bottlenecks in distributed computing environments.
