Professionally, I develop open source technical documentation for systems and infrastructure software. I have more than 12 years of experience as a technical writer, developer, and system administrator. I also provide consultation and audit services for technical documentation, with a focus on usefulness, correctness, clarity, structure, and automation.
My professional contributions in the last 6 years are in open source documentation repositories. The pull requests are rigorously reviewed from technical and editorial perspectives.
This section contains my notes as PDF files that are free to download and use. However, the notes may get obsolete, or simply contain wrong information; use them at your own risk.
