01
Start from the question
Every project begins with a decision someone has to make. If the query doesn't change an action, it doesn't ship.
02
Engineering-grade SQL
CTEs over nested subqueries, indexes over hope, execution plans over guesses. Queries are read more than they're written.
03
Documented like a product
READMEs, schema diagrams, assumptions and limitations. A repo a stranger can run is the minimum bar.
Featured Work
Projects built around questions a business actually asks.
Each repository ships with documentation, assumptions and the query design behind the answer.
SQL Engineering Handbook
A 20+ module production-quality knowledge base covering advanced SQL, performance tuning, data modeling and real-world query design — with a full resource library and community health docs.
NagpurLens
An urban intelligence platform mapping infrastructure gaps and growth signals across 57 Nagpur localities using custom KPIs — density, healthcare access, investment attractiveness.
