Month: 2025-09 – Performance review for hmcts/dlrm-data-ingest-infra. Delivered two key features and supporting fixes that improve sandbox reliability, onboarding speed, and repeatable deployments for landing zones. Sandbox legacy SQL VM provisioning and cleanup enhanced the sandbox environment for legacy SQL ingestion by extending the ingest05-legacy-sql sandbox OS disk, adding a dedicated VM configuration for the legacy SQL server, and removing an obsolete test VM configuration to simplify maintenance. Landing zone bootstrap script support introduces an optional bootstrap_script for landing zones, demonstrated in the sandbox to install cloud-utils and resize the root filesystem.

In August 2025, delivered foundational data-ingest infrastructure enhancements for hmcts/dlrm-data-ingest-infra and stabilized deployment workflows to support secure data migration and scalable operations. Focused on enabling Crime Legacy migration, tightening access controls, aligning Linux-based infrastructure, and stabilizing provider versions to reduce risk and improve reproducibility across landing and ipkit_logic modules.

July 2025 monthly summary for hmcts/dlrm-data-ingest-infra: Delivered major infrastructure improvements focused on stability, security, and production readiness. Key changes include: (1) Infrastructure cleanup and stabilization of Terraform configs, removing unused vars/blocks and correcting references to improve maintainability and reduce drift; (2) Terraform data integrity and lifecycle safety, tightening resource lifecycles to prevent accidental deletions and reducing production access for security; (3) Production readiness and capacity upgrades, including OS disk expansion, VM size upgrades, Docker image updates, and environment tagging to improve performance and operability; (4) Overall impact: these changes reduce operational risk, enable safer deployments, and deliver measurable business value through improved stability and capacity for production workloads.

June 2025 monthly summary focusing on key accomplishments, with highlights on features, bugs, and infra improvements across libragob-batch-jobs and dlrm-data-ingest-infra. Delivered multi-database AMS reporting capabilities, improved security by removing hard-coded credentials, restored password safeguards, expanded MoJo Prisma network access, and upgraded production VM image and disk sizing. Result: more reliable reporting, better data reconciliation, hardened security, and scalable infra.

May 2025 performance summary: Delivered cross-repo improvements spanning test environment governance, reliability hardening for Traefik, container tooling modernization, CI/CD resilience, and secure, per-environment infrastructure. These efforts reduced testing risk, stabilized long-running workloads, streamlined developer workflows, and strengthened security/compliance across cloud resources.

April 2025 monthly summary for hmcts/dlrm-data-ingest-infra: Delivered F5 integration enablement in the data landing zone via Terraform updates, resolved sandbox subnet clash, and reverted to a stable Terraform module main branch to ensure consistency. These changes enhance secure traffic management, reduce sandbox risks, and improve deployment reliability for the data ingestion infra.

March 2025 monthly summary for hmcts/dlrm-data-ingest-infra and hmcts/cnp-flux-config. Delivered key infra enhancements, strengthened security controls, and improved deployment reliability, enabling safer testing and faster iteration of data ingestion and governance pipelines. Highlights include: Key features delivered: - Sandbox Environment Zone Configuration: added test zone; introduced a second zone (02) for the DLRM Ingestion Engine; fixed zone keys; adjusted sandbox configurations including RBAC and cleanup of unused sandbox configs. - Bastion and SFTP Deployment and Access Controls: enable and manage Bastion deployments and SFTP storage in the data landing zone, including conditional deployment, broadened access, and related module updates to support testing and security controls. - Network Address Space Optimization: fix and optimize CIDR calculations, subnet allocations, and address spaces across data landing zone components to improve network segmentation and service placement. - CI/CD Pipeline Enhancements for Purview: improve CI/CD reliability around Azure Purview: ensure Purview extension is available in pipelines and enforce immediate failure on errors to prevent downstream issues. - HMCTS Sandbox Access Provisioning: provision HMCTS domain access in the sandbox environment to broaden test coverage and ensure HMCTS users are provisioned correctly. Major bugs fixed: - CIDR logic corrections and address space reshuffle improving network reliability. - Production image rollback for CCD API gateway web in production to a previous stable version. - Bastion deployment reliability improvements (ensured deployment in STG/PROD and removed Bastion source address restrictions). - Guarded against unintended deployments of Bastion or SFTP storage in inappropriate contexts. Overall impact and accomplishments: The month delivered tangible improvements in test coverage, security posture, and release reliability. These changes enable faster, safer experimentation in HMCTS sandboxes, strengthen governance tooling with Purview, and reduce production risk through robust networking and deployment controls. Technologies and skills demonstrated: - Terraform and infrastructure-as-code for sandbox and landing zone configurations - Azure Purview integration in CI/CD pipelines - Advanced networking: CIDR/subnet calculations and address space optimization - RBAC design and access provisioning for sandbox environments - Bastion/SFTP deployment automation and security controls - HMCTS domain provisioning in sandbox environments

February 2025: Delivered a CI/CD Pipeline Rebuild Trigger for hmcts/rd-shared-infrastructure by applying a non-functional newline change in Jenkinsfile_CNP to force a CI/CD re-run without touching production code. No major bugs fixed this month. Impact: accelerated CI feedback and safer pipeline changes, improving release readiness. Technologies/skills demonstrated: Jenkinsfile-based pipeline tuning, Git commit hygiene, CI/CD best practices, and release engineering.

Month: 2024-11 — Focused on reliability, scalability, and safer experimentation across IaC and cloud deployments. Delivered network routing integrity fixes for AKS/App Gateway, introduced a sandboxed DLRM Ingestion Engine zone with access controls, expanded Event Hub capacity configurability, and cleaned up landing zone modules to rely on dynamic resource group references and remove obsolete settings. These changes reduce connectivity issues, enable isolated testing, and streamline configuration management, delivering measurable business value in uptime, test velocity, and scalability.
