Thr3ds QA Service

Thr3ds is an e-commerce clothing retailer. For this project I inhereted legacy front-end code in react and was tasked with building out and prototyping an optimized back-end that could handle high throughput web traffic. I worked with two other teammates, each of us focusing on a different microservice.

Acheivements and Optimizations

  • Seeded a MongoDB database with 10 million primary records amounting to 18 GB of raw data
  • Optimized MongoDB query times by over 90% with indexing
  • Reached a throughput of 2000 requests per second with an average response time of 50ms
  • Implimented horizontal scaling and caching using an NGINX load balancer
