Project: ShoeCase - back-end system design of a full-stack shoe product app

• Designed RESTful API to handle CRUD operations and benchmarked MongoDB and PostgreSQL to determine optimal database based on performance under load with 12 million seeded data.

• Scaled microservice horizontally across twelve AWS EC2 instances behind an NGINX load balancer to handle over 3100 requests per second, with below 500ms latency.

• Implemented caching with Redis for effective read operations and further improved latency by 120%.

• Stress tested high traffic load with Loader.io and K6. Identified system bottlenecks by collecting performance metrics using New Relic and AWS Cloudswatch.
