StayEase - Microservices

-- Built a scalable microservices-based hotel booking platform with 3 independent services for hotels, bookings, and notifications. – Guaranteed exactly-once bookings at scale by combining idempotency keys with Redis Redlock distributed locking, eliminating race conditions and concurrent double-booking risks. – Decoupled critical flows with async processing: Redis-backed queues for notifications and an event-driven review service to update hotel ratings without impacting checkout latency. – Integrated comprehensive tooling with ESLint, Prettier, Husky pre-commit hooks, and automated code quality enforcement.
