A simple newsletter subscription form without API rate limiting triggered a cascading production outage on a logistics platform. Unthrottled requests caused database connection exhaustion, depleted third-party email quotas on Resend, and generated costly infrastructure bills. Learn how to implement Redis-backed sliding window rate limiting, decouple email dispatch with message queues & bot. #RateLimiting #SystemDesign #DevOps #SRE #Nodejs #Redis #Cybersecurity #WebSecurity #BackendDevelopment
Manual or synchronous bulk payment processing is highly vulnerable to network timeouts, rate limits, and system crashes. This technical guide explains how to engineer a fault-tolerant, high-throughput payroll disbursement engine using Node.js, Express, and the Monnify payment gateway, decoupled by a Redis-backed BullMQ background task queue. #Nodejs #ExpressJS #Fintech #Monnify #BullMQ #Redis #BackendDevelopment #APIs #SoftwareArchitecture #SystemDesign #QueueManagement #PaymentGateway
