vim89 - Overview

Hi, I'm Vitthal

Staff Engineer | Data Architect · Scala · Functional programming · Spark · GCP

• I build data platforms and Scala tools that fail early and run calm. I like sleep.

• Writing: vitthalmirji.com

• Rock the JVM: Articles

• Resume: vitthalmirji.com/resume

• 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:
    • cask
    • scalasql

• Ask me about: data engineering, data contracts, Scala, Functional programming, Spark/Databricks, GCP BigQuery, Kafka/Flink, and clean APIs.

What I do

• 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.

Writing

• I write technical posts on type-safe data engineering, Scala patterns, and production lessons.
• My posts on vitthalmirji.com have crossed 25K+ views.

Talks

• I speak at technical conferences on Scala, data engineering, and reliable AI systems.
