During a two-month period, John Naulty developed secure signing capabilities and enhanced CI reliability across two repositories. For dwallet-labs/dwallet-network, he built an AWS KMS Signer in TypeScript, integrating AWS Key Management Service to enable secure transaction signing with a dedicated client and signer implementation. He updated build workflows and dependencies to support this feature, improving onboarding for security-focused development. In Shubhamsaboo/eliza, John strengthened CI/CD by modifying GitHub Actions workflows to run integration tests against the PR target branch, using YAML and JavaScript. His work addressed security and reliability, demonstrating depth in cryptography, CI/CD, and full stack development.
