# Vaibhav j on Tal

## Headline

Backend Engineer \| Node\.js, PostgreSQL \| Auth, APIs, Data Integrity

## About

I build backend systems with a focus on authentication, data integrity, and safe handling of concurrent operations\. I built OrgOps, a multi\-tenant project and access management system using Node\.js and PostgreSQL\. It includes role\-based access control, refresh token rotation with replay detection, and transaction\-safe workflows designed to prevent race conditions and enforce data correctness at the database level\. I’m interested in working on backend\-heavy products where system behavior, APIs, and data reliability matter\. Comfortable picking up new tools and contributing across the stack when needed\.
