Concise monthly summary for Feb 2025 focusing on WunderGraph Cosmo repo contributions, highlighting delivered features, fixed issues, impact, and skill application.

January 2025 — Wundergraph Cosmo: Delivered key features focused on observability, security, and reliability. Implemented engine metrics exposure, trace propagation interface, and telemetry attribute optimization; tightened GraphQL routing by removing wildcard paths and added tests; introduced health and readiness probes with startup verification; redesigned JWK/JWKs authentication to support multiple algorithms and JWKS configuration with improved token decoding. Also fixed metric configuration issues and ensured health checks run during startup.

December 2024 performance-focused delivery for WunderGraph Cosmo centered on router reliability, observability, and configurability. Delivered features include GraphQL operation naming and subgraph fetch configuration in router (cleaner traceability, tested), telemetry and metrics improvements (operation cache metrics, OpenTelemetry attributes, and cardinality limit enforcement), cache efficiency improvements for Ristretto caches, router configuration enhancements (configurable max header size and Prometheus endpoint defaults), and a test infrastructure stability fix addressing a data race in integration tests. Major bugs fixed include a data race in integration tests and several smaller telemetry/config fixes. Overall impact: improved traceability, monitoring, and runtime performance; reduced risk in CI and production; better defaults and configurability reducing operational overhead. Technologies demonstrated: Go, GraphQL, OpenTelemetry, Ristretto caching, testing concurrency patterns, and infrastructure/configuration management.
