🔥 Featured Projects

OOPS - Operations Optimization & Python Scripts

OOPS is a collection of production-inspired Python projects built around real-world system administration scenarios.

Each project starts from a practical operational problem ("ticket") and evolves into a reusable command-line tool with clean architecture, documentation, and reporting capabilities.

The goal of this repository is to:

Learn Python through practical automation Solve common Linux administration tasks Build reusable command-line utilities Share production-inspired solutions with the community
