Fashlyer
Project Overview
Fashlyer is a next-generation ticketing and event management ecosystem designed to handle massive spikes in concurrent traffic. When popular artists announce tours, traditional platforms often experience crash events due to lock contention in standard database schemas. We designed Fashlyer to eliminate these bottlenecks, implementing an optimized booking engine capable of high-throughput transactional processing.
The Challenge
The client's legacy database could not scale to handle high-traffic concurrent users during ticket flash sales, causing database locking and double-booking bottlenecks.
The Solution
Designed a resilient PostgreSQL database optimization solution, isolating heavy reads and using row-level locks and raw Node.js backend transactions to ensure ACID compliance.
The Outcome
Successfully managed 5K+ concurrent ticket bookings per minute with zero transaction lockups or double-bookings.
Key Features & Capabilities
- •Real-time ticket inventory synchronization using WebSockets and row-level locks.
- •Optimized query execution plans isolating active sales read-pools from administrative writes.
- •Automated queue system that gracefully controls surge traffic during peak flash sales.
- •Seamless integration with international and domestic payment processors (Stripe & Razorpay).
Technical Architecture
- •Frontend: React.js and Tailwind CSS with server-assisted layout optimization.
- •Backend: Node.js Express framework implementing asynchronous queues.
- •Database: PostgreSQL utilizing indexes, raw transactional query blocks, and SELECT FOR UPDATE locks.
- •Infrastructure: Deployed on AWS with automated auto-scaling and Redis-based caching layer.
