March 2025: Delivered container security hardening for the insolvency-delta-consumer service by enabling read-only root filesystem for ECS containers and updating the secrets module. No major bugs fixed this month. The change was committed as 6b4fe28537df811307fee6592fe5b9b7f28739fa (set read_only_root_file_system to true). This work reduces runtime modification risk, enhances secret management, and strengthens production security with minimal rollout impact.

January 2025 monthly summary focused on internal code quality hygiene for the companieshouse/limited-partnerships-api repository. No new feature work delivered; one code quality cleanup was completed to improve maintainability and reduce future diffs. The change establishes a clean baseline for upcoming feature development.

December 2024 monthly summary focused on stabilizing and modernizing ECS infrastructure through Terraform configuration cleanup and module upgrades across two repositories.

2024-11 Monthly Summary for limited-partnerships infrastructure: Key features delivered: - Multi-load Balancer support and monitoring enhancements: added a secondary load balancer data source, configured listener routing for primary and secondary LBs, and enabled optional CloudWatch alarms with a sensible default. - ECS root filesystem security hardening: enforced read-only root filesystem with controlled /tmp write and ensured deployment sequencing by depending on the secrets module. - Terraform module maintenance and cleanup: updated ECS service and secrets module versions and removed unnecessary temporary mount configurations to align with latest modules and best practices. - Terraform module upgrades in web app: upgraded ecs/secrets and ecs-service Terraform modules from v1.0.293 to v1.0.294 to improve stability and compatibility. Major bugs fixed: - No explicit user-reported bugs fixed this month; security hardening and module upgrades addressed configuration drift and potential risk, improving stability proactively. Overall impact and accomplishments: - Strengthened availability and scalability of the limited-partnerships API, with improved monitoring and deployment reliability. - Reduced operational risk through security hardening and up-to-date IaC modules, enabling faster, safer deployments. - Business value: higher resilience in production, clearer observability, and lower maintenance toil through standardized multi-LB patterns and aligned Terraform modules. Technologies/skills demonstrated: - Terraform, AWS ECS, Load Balancers, CloudWatch, security hardening, deployment sequencing, modular IaC upgrade practices, best-practice configuration management.

October 2024: Delivered end-to-end deployment automation and quality improvements for Limited Partnerships projects across web and API services. Implemented AWS ECS deployment pipelines with containerization, startup scripts, and Terraform-managed infrastructure, including environment-specific settings, health checks, and load balancer configurations. Integrated Vault-based credentials management and strengthened CI/CD with security checks, unit tests, coverage reporting, and SonarQube. Improved repository hygiene and logging strategy to support maintainability and security.
