Jon McAdam worked on the hmcts/cnp-flux-config repository, focusing on aligning the performance testing environment with production systems. He updated YAML-based configuration files to synchronize image references and policy patterns, ensuring that performance tests used the latest production and API images. Leveraging skills in configuration management, CI/CD, and DevOps, Jon addressed environment drift and improved the reliability of performance benchmarks. His targeted commits provided traceable, version-controlled infrastructure changes that reduced the risk of mismatched environments and stale test results. This work enabled faster detection of production regressions and supported safer, more accurate performance testing within the deployment pipeline.
February 2026: Stabilized performance testing by fixing configuration drift in hmcts/cnp-flux-config. Delivered a bug fix to synchronize the API image tag used by perf tests with the latest case-document-am-api build, ensuring tests run against current API versions and removing stale results. This improves test reliability, reduces debugging time, and provides clearer performance signals for API changes. Key commits: b830060dbf3150ca7433347ccbb4aa81960d3fce (Update perftest.yaml (#43191)).

In December 2025, delivered parity between the performance testing environment and production for the hmcts/cnp-flux-config repo. Updated the perf test image reference in perftest.yaml to the latest production image and refined image policies to reflect production tag patterns and image references. Implemented via two commits: cac7876db6f90b9487640d216505ae53db4d3c54 (Update perftest.yaml) and eba38b9cd074d3962a8f933205dfac4c72d7dc67 (Update perftest-image-policy.yaml and related updates). The changes close env drift, improve perf test reliability, and enable faster detection of production regressions. Demonstrated proficiency with YAML-driven configuration, image policy governance, and version-controlled infrastructure changes. Business value: reduces risk of environment mismatch, increases confidence in performance benchmarks, and supports safer, faster production releases.
