Hey, I'm Shailesh Chalke 👋

Senior Snowflake Data Engineer · 13 Years in Data · Pune, India
I migrate legacy Oracle/SQL Server systems to Snowflake — faster, cheaper, cleaner.


🧑‍💻 About Me

I've spent 8 years at MMF Systems keeping healthcare data clean and compliant, then moved into full Snowflake engineering at Azentio — leading a 3TB+ Oracle migration for a BFSI client. Now I consult independently, mostly fixing what others built too fast, or building it right from scratch.

Things I'm consistently good at:

  • Untangling Oracle/SQL Server legacy systems and landing them cleanly in Snowflake
  • Finding the warehouse settings silently burning 30-40% of your Snowflake bill
  • Building dbt pipelines the next engineer won't have to rewrite

Currently open to: Senior Snowflake roles (full-time) and freelance consulting engagements.
