PROFILE

Mike Brown

Worked on the hmcts/probate-back-office and related repositories to deliver robust backend features, focusing on configuration management, security hardening, and maintainability. Implemented centralized mutation testing and dependency management using Java and Gradle, improving CI/CD reliability and reducing version drift. Enhanced observability and deployment hygiene by refining Helm charts and logging, while addressing vulnerabilities through targeted security patches. Reorganized case field configurations and authorization flows, leveraging JSON and Kubernetes to streamline WA task enablement and data modeling. The work emphasized incremental improvements, safer deployments, and clearer role-based access, resulting in more reliable, maintainable, and secure backend systems for operational teams.

Jun 1, 2026

In June 2026, the probate back-office efforts centered on stabilizing and simplifying the GrantOfRepresentation authorization flow, reorganizing case field configurations for maintainability, and expanding WA-focused capabilities. Key UI and CI/CD improvements were implemented to support PROBATE_WA, with gating and UI updates to display Available Tasks. The work reduces maintenance risk, eliminates deprecated fields, and improves the reliability and speed with which WA users can access and process tasks, delivering clearer role-based access and a smoother operator experience.

2026-05 monthly summary for hmcts/probate-back-office. Focused on stabilizing WA Preview in production, maturing the data model for case and authorisation fields, and incrementally refactoring configuration and definitions to improve maintainability and future feature delivery. Delivered a robust ElasticSearch fix for WA Preview, introduced safe defaults for message publishing, and expanded field coverage (mandatory fields, location/roleCategory, and caseManagementCategory) with an incremental file approach to definitions and mappings. Performance and reliability improvements support faster case processing and better data quality for downstream workflows.
