Pandiyaraj Karuppasamy
I lead test automation and engineering teams in the physical security / access control industry, building the frameworks, CI/CD pipelines, and developer tooling that ship real products. I publish production tools as open source on PyPI, and I teach — my courses on GitHub Actions, prompt engineering, and context engineering are written for working QA and development engineers.
