Indrasenareddy Annapureddy

Data Engineer with 5+ years of experience building scalable batch and streaming data pipelines. I work across the modern data stack, turning raw data into reliable, well-tested analytics products from ingestion and orchestration through modeling and serving.

Currently a Data Engineer at Progressive Insurance, where I design and operate production ETL/ELT pipelines.

Open to new opportunities reach me on LinkedIn.

Stack

Python SQL Apache Spark Kafka Airflow dbt Databricks Snowflake AWS Azure

Pinned projects

A few portfolio builds that show how I work:

  • pyspark-etl-pipeline end-to-end batch ETL in PySpark with SCD Type 1 handling, partitioned Parquet output, data-quality gates, and pytest coverage.
  • airflow-data-pipelines production-style Airflow DAGs: a daily ETL with retries and SLAs, plus a backfill-friendly partitioned pipeline.
  • dbt-analytics-engineering layered dbt project (staging → intermediate → marts) with data tests and docs, running locally on DuckDB.
