SalonX & TheQube
Enabling secure tenant isolation and conflict-free booking slots.

1. Challenge & Constraints
Preventing slot double-booking concurrency conflicts during peak user traffic and ensuring secure tenant data isolation in a shared database schema.
2. Architectural Solution
To solve these bottlenecks, the system was built using the following core patterns:
- Implemented white-label tenant isolation using PostgreSQL Row-Level Security (RLS) policies.
- Engineered scheduling transactional guards using PostgreSQL advisory locks to guarantee zero concurrency scheduling conflicts.
- Integrated Stripe billing engines to automate credits, refunds, and subscription tiers.
3. Measured Outcomes
- Achieved zero double-booking scheduling conflicts across all tenant environments.
- Maintained 99.99% system uptime during high-volume booking traffic.
- Automated tenant billing operations, decreasing manual support tickets by 75%.
