High-Traffic API Platform

NestJS microservices powering high-traffic logistics APIs, re-architected to cut latency at millions of requests per day.

About the project

An engagement designing and maintaining NestJS microservices behind high-traffic APIs for an e-commerce logistics platform. Legacy systems were migrated to a scalable microservice architecture and moved onto message-driven communication with RabbitMQ and Redis. The platform handled one to two million slow, external-service-bound requests per day; profiling and re-architecting the hot paths and scaling them accordingly reduced response times by roughly 30–300%.

Impact

  • Sustained 1–2M slow, external-service-bound requests per day.
  • Response times reduced by roughly 30–300% on critical paths.
  • Message-driven design decoupled traffic spikes from core services.
