Hi, I’m Dheeraj👋

I’m a Data Engineer who enjoys turning messy data into clean, reliable datasets.
My sweet spot is data ingestion, transformations, and performance tuning I like making pipelines faster, cheaper, and easier to trust.


What I do

I work on:

  • Building batch + streaming pipelines
  • Handling multiple file formats (CSV, JSON, Parquet, Avro, etc.)
  • Writing clean transformations (SQL / PySpark / Python)
  • Improving performance (partitioning, joins, caching, pruning, cost tuning)
  • Adding data quality checks and monitoring so failures get caught early

What I’m currently working on

Right now I’m focused on:

  • Strengthening my end-to-end pipeline projects (realistic datasets + production-style structure)
  • Writing better tests + data quality validations
  • Sharpening performance patterns in Spark + SQL

Tools I use

Languages: SQL, Python
Big Data: Spark / PySpark / Databricks Orchestration: Airflow
Cloud: AWS / Azure / GCP
Warehouses: Snowflake / BigQuery / Redshift
Dev: Git, GitHub Actions, Docker
Data Quality/Observability: Great Expectations / Deequ / CloudWatch / Datadog


Outside work

When I’m not building pipelines:

  • 🏐 Beach volleyball
  • 📷 Photography
  • 🚁 FPV drones (landscape flying & filming)
  • 🍜 Trying new cuisines
  • 🎧 Classic + hip-hop
