        cd /Users/kjannette/workspace/koin_ping_0.2.0/backend go run ./cmd/api
        
        make run — Builds and runs the API server.
        make dev — Runs the API server with auto-reload via air (falls back to go run if air isn't installed).

## 5.   Terminal 2 (Poller):
        cd /Users/kjannette/workspace/koin_ping_0.2.0/backend 
        go run ./cmd/poller

        make poller — Builds and runs the poller.
        make poller-dev — Runs the poller with auto-reload.
