Technical Highlights

CQRS Pattern

Commands, queries, and domain events for clean separation of read and write paths — implemented identically in NestJS and Go.

Testcontainers

Isolated PostgreSQL per test run with zero shared state between suites.

3-Backend Benchmark

NestJS, Go, and Spring Boot implementing the same API with matching caching configs and CI for fair performance comparison.

In-Memory Caching

LRU cache with 5 min TTL and per-id eviction, implemented consistently across all three backends.
