Melissa Kilby contributed to multiple open source projects, focusing on security, observability, and developer experience. In grafana/falco, she enhanced metrics instrumentation and Prometheus integration using C++ and YAML, delivering immediate startup and reload metrics while clarifying runtime configuration and documentation. For swiftlang/swift-org-website, she improved onboarding documentation for the Static Linux SDK, streamlining cross-platform guidance with Markdown. In October, Melissa implemented least-privilege GitHub Actions workflow permissions across seven Swift repositories, applying CI/CD and security best practices to reduce attack surface and align with OpenSSF standards. Her work demonstrated depth in system programming, DevOps automation, and technical writing.
October 2025 highlights: Implemented and hardened GitHub Actions workflow permissions across seven Swift/Open Source repositories, delivering least-privilege CI/CD configurations while preserving build/test reliability. Key feature deliveries include granular read permissions for CI/CD workflows in apple/swift-nio across cxx-interop, benchmarks, release-builds, execute-matrix, and unit-tests. Expanded security hardening across swiftlang/swift-testing, swiftlang/vscode-swift, swiftlang/swift-java, apple/containerization, and apple/container to enforce read-only contents at the ecosystem level and per-job scopes. Major bug fix in swiftlang/github-workflows to restrict the contents permission in soundness.yml to read-only, closing a security gap. Overall impact: reduced attack surface, stronger governance, and a future-proof security posture that aligns with OpenSSF defense-in-depth. Technologies/skills demonstrated: GitHub Actions workflow permissions, YAML-based security policies, least-privilege design, security automation, cross-repo policy enforcement.

May 2025 performance summary for grafana/falco: Focused on strengthening observability and reliability through metrics instrumentation and Prometheus metrics correctness across multiple inspectors and event sources. Delivered immediate startup/restart/hot-reload metrics, introduced a restart timestamp metric and renamed it to reload_ts, and streamlined runtime config logging. Implemented runtime config clarifications and moved generated configs to a clearly commented section. Fixed metric deduplication and source ordering in the Prometheus integration, updated documentation to reflect clarified metrics collection behavior, and improved inspection loop semantics.
