PROFILE
Mike Halma
Over nine months, contributed to the ministryofjustice/cloud-platform-environments repository by engineering event-driven cloud infrastructure for justice data workflows. Delivered and maintained AWS SQS and SNS-based queueing systems for prisoner movements, court events, and address changes, implementing robust dead-letter queues, IAM policy refinements, and Kubernetes secrets for secure metadata management. Used Terraform and YAML to codify infrastructure as code, ensuring reliable, scalable, and observable data processing across development, pre-production, and production environments. Enhanced real-time event handling, improved fault tolerance, and streamlined migration patterns, while maintaining repository hygiene and traceability through disciplined commit practices and environment-specific configuration management.

Apr 1, 2026April 2026 highlights: Delivered two new features in ministryofjustice/cloud-platform-environments to strengthen event-driven handling of temporary absence for prisoners. Implemented unscheduled temporary absence event listening via AWS SNS and the domain events queue, and added support for paused/resumed events in temporary absence authorization. These changes enable real-time, auditable processing, improve compliance oversight, and reduce latency in absence decision workflows. No major bugs reported this month; engineering focus on reliability and scalability. Technologies demonstrated include AWS SNS, domain events, and event-driven architecture.

Jan 1, 2026January 2026 monthly summary for ministryofjustice/cloud-platform-environments. Key deliveries focused on strengthening event-driven stability for external movements. - Enhanced temporary absence event handling: broadened subscriptions to external movement events related to temporary absence authorizations and added targeted listeners for deferred events to improve system responsiveness and accuracy. - Increased dead-letter queue and redrive policy reliability for external movements: raised the maximum receive count and refined the redrive policy to improve message processing resilience and reduce the risk of missed events. - No-op placeholder commits: a set of placeholder commits with no functional changes; no user-facing impact, maintained for release hygiene. Overall impact: improved reliability and responsiveness of the external movements workflow, reducing retries and potential data loss, and delivering tangible business value through more timely processing and fault tolerance. Technologies/skills demonstrated: event-driven architecture enhancements, AWS SQS dead-letter queues and redrive policy tuning, expanded event listener patterns, release hygiene and traceability.

Nov 1, 2025Month: 2025-11 — Delivered real-time address-change handling by consolidating AWS SNS subscriptions to listen for address update events across offenders, corporate entities, and agencies. Updated the prison events queue to reflect address changes in real time and improve data accuracy. Achieved multi-environment rollout (dev, preprod, prod) in ministryofjustice/cloud-platform-environments with SDIT-3150/3153 work items. This work lays the foundation for improved data integrity and downstream case-management workflows.

Oct 1, 2025October 2025 (2025-10) monthly summary for ministryofjustice/cloud-platform-environments. Business value focus: enhanced reliability and throughput of queue processing to support higher load with lower risk of message loss and retries. Delivery concentrated on increasing the queue max receive count (SDIT-3046) across the environment, plus groundwork and maintenance for kick functionality. The work demonstrates strong change management, traceability to SDIT-3046, and a disciplined approach to bug fixes and scaffolding. Key outcomes: - Increased queue max receive count (SDIT-3046) to better handle peak workloads and improve processing throughput, with changes consolidated across multiple commits. - Kick handling bug fix: corrected kick semantics to prevent incorrect removals and ensure proper queue behavior. - Kick-related scaffolding and maintenance: baseline and miscellaneous kick commits to prepare for future functionality and maintain code hygiene. - Improved maintainability and traceability: consistent SDIT-3046 tagging across commits and clear commit messages to support future audits and rollbacks.

Sep 1, 2025Month 2025-09: Delivered end-to-end external movements data ingestion for prisoner-to-NOMIS across development, pre-production, and production. Implemented AWS SQS queues (main + DLQ) and SNS subscriptions with IAM policies and Kubernetes secrets, enabling reliable, multi-environment data flow. Established RBAC provisioning to grant developer and GitHub groups access to external movements namespaces (dev and pre-prod), accelerating development and operations. Fixed production issues by refining the SNS subscription filter policy, ensuring all relevant events are processed, and addressed production build stability with a series of build fixes. Performed housekeeping commits with no user-facing impact to reduce noise. Overall, improved data reliability, security, and developer velocity, delivering measurable business value through safer, scalable data integration and faster iteration cycles.
