PROFILE
Karlkern
Over four months, contributed to the nationalarchives/ds-infrastructure-web repository by designing and deploying cloud infrastructure using Terraform and AWS, with a focus on maintainability and automation. Developed a comprehensive Draw.io architecture diagram to document AWS resources and their interconnections, supporting onboarding and cross-team clarity. Built modular, environment-specific infrastructure for web frontend and Cognito authentication, implementing autoscaling, IAM roles, load balancers, and Route 53 DNS. Automated CI/CD pipelines with GitHub Actions, reducing manual deployment steps and improving environment parity. Emphasized Infrastructure as Code principles, using HCL, YAML, and Bash scripting to streamline provisioning, enhance reliability, and enable faster, safer releases.

Oct 1, 2025October 2025 — NationalArchives/ds-infrastructure-web: Key feature delivered: Automated CI/CD deployment for the request-service-record service with a GitHub Actions workflow and Terraform configurations, enabling automated deployments across dev, staging, and live environments and defining AWS infrastructure (EC2 instances, auto-scaling groups, load balancers). A subsequent commit updated workflow naming conventions for consistency in resource naming. Major bugs fixed: No major bugs documented for this repo in October 2025. Overall impact and accomplishments: Reduced manual deployment steps, improved deployment reliability and environment parity, enabling faster iteration and safer releases. Technologies/skills demonstrated: GitHub Actions, Terraform, Infrastructure as Code, AWS architecture (EC2/ASG/Load Balancer), and naming conventions standardization.

Sep 1, 2025Sep 2025 monthly summary for nationalarchives/ds-infrastructure-web: Focused on delivering modular infrastructure enhancements with Cognito-driven deployment and environment-aware email configurations. Key business value: improved deployment flexibility, environment isolation, and maintainability. No explicit bug fixes recorded this month. Highlights include: conditional Cognito deployment with Route 53 DNS integration, migration of DNS resources into the Cognito module, and environment-specific email address configurations across dev/stage/live with a -web suffix. Impact: clearer separation of concerns, faster, safer deployments, and reduced risk of environment misrouting.
