Tom Eldridge developed and maintained the NHSDigital/eligibility-signposting-api over six months, delivering features that improved deployment reliability, data security, and rule processing accuracy. He engineered Terraform-based infrastructure provisioning, automated CI/CD pipelines, and IAM policies to support secure, auditable deployments across multiple environments. Using Python, Bash, and Terraform, Tom implemented cohort-specific rule evaluation, manual data upload tooling for S3 and DynamoDB, and robust KMS encryption for external write roles. His work modernized deployment workflows, enhanced audit capabilities, and ensured compliance with data protection standards, demonstrating a strong grasp of backend development, infrastructure as code, and cloud security best practices.

Jul 1, 2025Monthly summary for 2025-07: Key feature delivered — secure DynamoDB encryption policy for external write role in NHSDigital/eligibility-signposting-api. Implemented an IAM policy granting KMS encrypt/decrypt/generateDataKey permissions to the external write role for the DynamoDB table's KMS key, enabling secure encryption operations for writes. Commit: 295bcdfd88033fb8e4a0952b00df0ae32111eb91. Impact: strengthens data protection, supports compliance (data-at-rest encryption for external writes), and reduces risk of misconfigurations in secure write paths. Technologies/skills demonstrated: AWS IAM, AWS KMS, DynamoDB, policy as code, security governance.
