PROFILE
Jon Soloway
Jon Soloway engineered robust performance testing and configuration management solutions in the hmcts/cnp-flux-config repository over a ten-month period. He focused on enhancing test reliability and deployment safety by refining perftest scheduling, introducing safety controls, and optimizing resource usage for PostgreSQL-backed batch updates. Leveraging technologies such as Kubernetes, Helm, and SQL, Jon streamlined CI/CD workflows and improved test fidelity by aligning image policies and managing JVM options across services. His work addressed real-world governance and capacity planning challenges, resulting in more maintainable, traceable, and production-aligned test environments that reduced risk and accelerated feedback for performance-critical changes.

Jan 1, 2026January 2026 monthly review for hmcts/cnp-flux-config focused on stabilizing performance test environments, expanding PR-testing coverage across frontends, and tightening JVM options management to improve reliability and reduce risk in performance validation. Key outcomes include production-image-based perftest stability, PR-image testing for the Citizen frontend, and a controlled rollback of custom JVM arguments in HMC to preserve test integrity. These efforts reduce deployment risk, accelerate feedback on performance changes, and strengthen the overall testing pipeline.

Nov 1, 2025Monthly wrap-up for 2025-11: In hmcts/cnp-flux-config, shipped a focused set of performance testing environment enhancements for the Sptribs case API, with multiple commits to align image tagging, refine image policies, support decentralised service URLs via environment variables, and implement memory optimizations to improve test reliability and speed. This work also aligns with CCD decentralisation to ensure testing reflects production conditions, improving performance measurement fidelity and reducing flaky tests. No distinct bug fixes were recorded this month; the primary value lies in making the performance testing pipeline more realistic and maintainable, enabling faster feedback for performance-related decisions.
