A few things I ship:
- flowforge - Type-safe Scala data engineering toolkit with compile-time contract validation. Prevents schema drift before deploy
- llm4s - reliable LLM apps in Scala
- compile-time-data-contracts - schema checks that break the build, not prod
- abortable-bytes - cancel-safe cloud uploads (scala/kyo POC)
- toon4s - token-friendly JSON for LLM work
- datapipelines-essentials-python - practical helpers for ETL in Python/Spark
- I also contribute to:

- I ship reusable data frameworks that cut delivery time and reduce incidents.
- I run large Spark/Databricks pipelines with sub-2h freshness.
- I modernize old data estates, reduce infra cost, and push SLAs up.
- I build data-quality automation so QA doesn't take 3 days.
- I write technical posts on type-safe data engineering, Scala patterns, and production lessons.
- My posts on
vitthalmirji.comhave crossed 25K+ views.
- I speak at technical conferences on Scala, data engineering, and reliable AI systems.
