Improve reliability, scalability, and maintainability of customer-facing services under sustained load.
Strengthen connection setup, authentication flows, session handling, and service behavior across real-time workloads.
Build observability: structured logs, metrics, dashboards, alerts, and operational tooling.
Improve visibility into push notification delivery to trace failures to APNs and FCM.
Diagnose production issues across application, networking, and client connectivity boundaries.
Improve deployment processes, rollout safety, and production readiness for distributed services.
Turn recurring customer and operational issues into durable engineering improvements.
