Client Task Tracker: Multi-tenant task tracking for Tsan Technologies

What I built

Architected a multi-tenant data access layer using a reusable database abstraction with 4 tenant-scoping primitives, strictly enforcing isolation and authorization boundaries across 8 relational tables.
Engineered robust authentication & RBAC via NextAuth, incorporating fail-closed security middleware, granular API access controls, forced password-reset flows, bcrypt hashing, and audit logging for sensitive role mutations.
Optimized PostgreSQL query performance by deploying 6 pg_trgm GIN indexes for fast fuzzy search and implementing cursor-based pagination (100 records/page) to minimize memory overhead and payload size.
Managed schema evolution and continuous integration across 15 additive SQL migrations via Supabase CLI, implementing environment-gated Vercel deployment pipelines for zero-downtime schema updates.
Enforced end-to-end data integrity and contract testing using Zod schema validation alongside automated regression checklists covering auth flows, RBAC enforcement, payload verification, and REST APIs.
