ArchUnitTS

I created and maintain ArchUnitTS, a software architecture testing library. It helps enforce architecture rules, detect circular dependencies, and ensure coding standards in TypeScript and JavaScript projects. Measured by GitHub stars, ArchUnitTS is the #1 architecture testing library for TypeScript projects.

TerraShark

I created TerraShark, a Terraform/OpenTofu skill that prevents IaC hallucinations by guiding LLMs through a failure-mode workflow. It’s token-efficient, security-first, and based on HashiCorp’s official best practices.
