Developed the AWS Cloud Expert Guidance Agent for the github/awesome-copilot repository, delivering a domain-specific assistant that provides actionable guidance on AWS services such as serverless architectures, databases, and security best practices. The agent was designed with production-ready defaults and integrated infrastructure-as-code tooling using AWS CDK, SAM, and CloudFormation, enabling repeatable and scalable deployments aligned with the AWS Well-Architected Framework. Addressed deployment reliability by resolving a validator naming issue, enforcing lowercase-hyphenated formats. The work demonstrated expertise in AI integration, DevOps, and cloud computing, supporting faster and safer AWS design decisions within the context of domain-specific automation.
