Multi-Tenant Hospitality Orchestration & POS Engine
GolfPay360 High-Concurrency Booking
A serverless-first booking platform built for “tee time drops” with strict tenant isolation, distributed locking, and POS/payment integrations that survive peak traffic.
The Challenge
Public and private golf courses face extreme traffic bursts (e.g., 7:00 AM “tee time drops”). Legacy monolithic platforms suffered race conditions, resulting in double-bookings and lost revenue.
The platform required a multi-tenant architecture that could scale to hundreds of courses while maintaining strict data isolation for each course’s financial records. Under peak traffic, the system must guarantee atomic bookings without degrading UX through heavy database locks.
Quick Stats
- Scale: Multi-tenant (hundreds of courses)
- Payments: PCI / online + card-present
- Concurrency: Distributed locking (Redlock)
- Impact: 84% digital conversion; zero double-bookings
The Solution
We architected a serverless-first booking platform designed for high-concurrency event handling. By moving away from a traditional database-locking model and toward event-sourced patterns, we eliminated collision errors during peak traffic.
The system separates browse from commit: availability is edge-optimized for low-latency reads, while booking writes are protected by distributed locks and idempotent retries. This keeps the tee sheet fast worldwide while guaranteeing atomic bookings at the point of transaction.
Technical Approach
- Distributed locking: Redis-based Redlock ensures atomic booking operations across multiple server instances.
- Edge-optimized availability: CloudFront Functions serve tee-sheet availability from the nearest edge location, reducing latency globally.
Technical Details
Architecture
Next.js (Frontend) → AWS Lambda → DynamoDB (NoSQL for sub-millisecond lookups)
Integrations
Clover/Square POS SDKs; Stripe Terminal for card-present transactions; Twilio Programmable Messaging.
Security
PCI-DSS Level 1 compliance; strict per-tenant isolation; JWT-based RBAC.
AI Features
Dynamic yield management suggests real-time price surges/discounts using weather data and historical no-show rates.
Results & Impact
- 84% digital conversion: shifted majority of bookings from phone to web/app.
- Zero double-bookings: since migration to distributed locking.
- 120+ admin hours saved: monthly per course through automated check-ins and self-service rescheduling.
