- Hybrid Storage Strategy: MySQL handles relational user data and match records; MongoDB stores high-frequency chat logs separately to prevent write contention and keep SQL tables lean.
- Redis Presence Layer: Online/offline user status offloaded entirely to Redis, eliminating expensive real-time MySQL polling and keeping presence lookups under milliseconds.
- Multi-Criteria Matchmaking Engine: Custom Laravel algorithm scoring compatibility across multiple profile dimensions with optimised query execution.
- Stripe Subscription Billing: Full subscription lifecycle management — plan creation, recurring billing, webhook-driven payment recovery for failed charges.
