PROFILE
Sam Whyte
Over six months, contributed to the nhsconnect/national-document-repository-infrastructure by delivering eight features and resolving two bugs, focusing on infrastructure automation, migration reliability, and operational simplicity. Work included decommissioning legacy modules, automating CloudWatch dashboard cleanup, and implementing scheduler-driven ECS data tasks using AWS, Terraform, and Shell scripting. Enabled segmented DynamoDB migrations with dedicated S3 buckets and Lambda orchestration, and introduced AWS Step Functions for robust migration workflows. Enhanced bulk data ingestion with SQS-triggered Lambdas and improved multi-environment deployment through workspace-aware naming and concurrency controls. Strengthened testing environments by refining API Gateway CORS and tightening sandbox access with DynamoDB policy integration.

Jan 1, 2026January 2026 monthly summary for nhsconnect/national-document-repository-infrastructure. Delivered two major updates increasing resilience and throughput in multi-environment deployments. Key features: CloudWatch-driven concurrency scheduler for bulk uploads during office hours with environment-aware Terraform workspace naming. Major bug fix: Lloyd George validation relaxed by disabling strict mode across environments, reducing workflow blockages. Overall impact: improved throughput during peak periods, fewer blocked workflows, clearer multi-environment organization, and reduced operator toil. Technologies/skills demonstrated: CloudWatch, Terraform workspace-aware naming, concurrency control patterns, risk mitigation in validation logic, enhanced observability.
