About Lagrange Labs

Lagrange Labs is a solo data engineering consultancy focused on helping companies build reliable, well-documented data infrastructure. I built LineagePro as a free community tool because understanding how data flows through SQL pipelines shouldn't require an enterprise contract.

What I Do

• Data Engineering — Pipeline development, warehouse architecture, and lineage tracking.
• App Development — Full-stack web and mobile applications built with modern frameworks.
• AI & Data Science — Machine learning models, analytics dashboards, and AI integration.

About LineagePro

LineagePro is a free SQL column-level lineage visualizer. Paste any multi-statement SQL pipeline and instantly see how data flows from source tables through intermediate transformations to target tables. It supports Oracle, MySQL, PostgreSQL, and Snowflake dialects, powered by SQLGlot.
