Fix Bugs & Stabilize a Multi-Tenant Web Application (Next.js + NestJS + PostgreSQL)

We're running a multi-tenant web application and need a developer to fix a set of issues and stabilize it. What needs to be done: - Fix bugs across the dashboard and tenant management modules - Resolve tenant isolation issues (data leaking between tenants in some views) - Fix auth-related problems (session handling, role permissions) - Clean up inconsistent API responses and error handling - General stability improvements - - Write tenant in capital letters on the proposal Stack: Next.js, NestJS, PostgreSQL, Prisma The codebase is already in production. Looking for someone comfortable working inside an existing multi-tenant architecture — someone who understands tenant isolation and can work carefully without breaking what already works. We'll share repo access after hiring and provide a list of known issues.
