A practical, growing collection of technical documentation, command references, code snippets and personal notes gathered through hands-on work in IT operations, system administration and automation.
The content focuses more on practical usage, less on theory-heavy explanations. Most notes originate from real production issues, panic-last-minute learning, troubleshooting sessions, automation work or day-to-day system administration tasks.
Topics may include:
- Operating systems & command-line tooling
- Scripting and automation notes
- Networking and infrastructure basics
- Deployment, configuration, and troubleshooting references
- General problem-solving notes I want to be able to reuse quickly
The structure evolves over time as the collection grows and gets refined.
Over the years, I’ve written a large amount of internal documentation, guides and notes while supporting complex environments. This repository is my effort to:
- Consolidate that knowledge into a single, searchable place
- Make my notes reusable for future projects
- Share practical references that might help others facing similar problems
Content is continuously added, reorganized, and refined as I migrate notes from other systems and expand the collection.
If something looks incomplete, it probably is 😊
