Backend Performance

High-Performance Supply Chain Platform

High-throughput product authentication and verification backend.

A Spring Boot verification backend for product authenticity flows, optimized through load testing, caching, profiling, and observability.

Challenge

Build a verification backend that stays fast when many product-authentication requests hit the same paths repeatedly.

Optimization

The work focused on measurable bottlenecks: lock-free request handling, targeted profiling, cache hit behavior, and idempotent APIs.

  • 7,152 RPS at 12.84ms P99.
  • 99.8% cache hit rate over 200k cached entries.
  • Explicit cache eviction paths for operational control.

Production Readiness

Prometheus/Grafana dashboards and GitHub Actions CI/CD make the backend easier to operate and safer to change.
