Jacob Woffenden engineered and maintained core analytics infrastructure for the Ministry of Justice, focusing on scalable data platforms and secure workflow automation. Working across repositories such as ministryofjustice/analytical-platform and ministryofjustice/analytical-platform-airflow, he delivered features like S3-based data ingestion, Airflow workflow automation, and robust observability with Grafana and CloudWatch. Jacob applied Terraform and Python to implement infrastructure as code, automate CI/CD pipelines, and enforce IAM governance, ensuring compliance and reliability. His work included integrating Kubernetes, AWS IAM, and secrets management, resulting in resilient, production-ready environments that improved deployment safety, data security, and operational efficiency for analytics and ML workloads.

October 2025 delivered foundational LLM-enabled platform infrastructure, expanded secrets management, and improved observability across four repositories. Key features included: LLM Gateway Cloud Platform Infra and IAM scaffolding (Kubernetes namespace, Terraform providers for AWS/Kubernetes, IRSA data structures); Development environment DNS and TLS configuration with Route 53, TLS certs, and dev gateway DNS; Monitoring and observability for LLM Gateway via ServiceMonitor and updated ingress policies. Expanded secrets management and Kubernetes/Helm integration across modernisation-platform-environments, wiring in LiteLLM and Azure OpenAI GPT-5, plus GitHub token, Slack, and Entra secret modules; IAM role enhancements and policy updates to support cross-team access. Deployment refinements for LLM Gateway (Route 53 NS for development, model ID updates, ingress allowlist enhancements, Prometheus values, and environment variable documentation). Foundational Data Platform infra bootstrap (Terraform-based) and governance improvements, including Graph API permissions refinements and Office of the CTO Terraform foundation. Additionally, CI/CD quality improved with Terraform plan summary automation for the analytical platform and cleanup of workflow configuration.
