Dec 1, 2025December 2025 — Delivered two high-impact features for CMSgov/bcda-app focused on reliability and external service integration. SSAS Health Check Reliability Enhancements introduced introspection checks, cached results, and retry logic to boost uptime and reduce latency. External Service Integration with BFD v3 finalized connections in both sandbox and production environments to improve interoperability with external services. There were no formal bug fixes logged this month; the work prioritized stability, observability, and external integration. Business value includes more reliable health monitoring, faster response times, and smoother cross-system communication. Technologies demonstrated include health-check patterns (introspection, caching, retries) and BFD v3 integration across environments (sandbox/production).
