Aaron Fowles engineered and maintained cloud infrastructure and data workflows across the alphagov/govuk-knowledge-graph-gcp and alphagov/govuk-infrastructure repositories, focusing on automation, governance, and reliability. He delivered Terraform-based provisioning for new GCP analytics projects, automated Docker image CI/CD pipelines with GitHub Actions, and enhanced data freshness monitoring using BigQuery SQL functions. Aaron improved deployment safety by introducing dual-environment workflows and strengthened alerting with Slack integration and runbook documentation. His work emphasized reproducible infrastructure, robust access control, and clear documentation, demonstrating depth in Infrastructure as Code, cloud IAM, and data engineering while addressing operational risks and supporting scalable analytics environments.
February 2026 monthly summary for alphagov/govuk-infrastructure: Delivered foundational setup for GA4 aggregate analytics and GDS-BQ processing projects, enabling scalable analytics and data processing with proper governance. Implemented new GCP projects, IAM bindings, and Terraform Cloud (TFC) workspaces to support reproducible infrastructure provisioning and governance. No major user-facing bugs were reported this month, and groundwork was laid for faster provisioning of analytics and data-processing environments.

January 2026 monthly summary focusing on business value and technical achievements across two repos: alphagov/govuk-knowledge-graph-gcp and alphagov/govuk-infrastructure. Key features delivered: 1) Data Freshness: Implemented calc_oldest_allowable_freshness scalar function in BigQuery to compute the oldest allowable freshness based on timestamp, with day-of-week adjustment; Terraform-instrumented deployment. 2) Publishing API: Extended change notes schema to include document_id and user_facing_version to improve version tracking; updated alerting policy to extend auto-close window from 2 hours to 1 day. Also minor documentation update to support RSS-to-Slack feed integration test. Major bugs fixed: Gov-search Deployment Readiness: Removed CNAME records for the gov-search service in infrastructure until the service is ready for deployment. Overall, delivered measurable improvements in data freshness governance, change/version visibility, and deployment readiness visibility, while maintaining and validating documentation touches. Technologies/skills demonstrated: BigQuery scalar functions, Terraform, Publishing API design, alerting configuration, infrastructure-as-code, readme/documentation hygiene, cross-repo collaboration.
