Great projects include building a personal backup/restore tool with rsync and rotation, creating a log parser that aggregates and summarizes server logs, writing a deployment wrapper for a small app using container CLI, and crafting cron-driven maintenance tasks that alert on failures. Other exercises are building a monitoring probe that emits metrics, automating database dumps, or packaging a set of admin utilities into a reusable script suite. Prioritize projects that touch real systems (containers, VMs, cloud CLIs) while keeping them reversible and safe. Post your project on the forum to get review and suggestions; community feedback transforms an okay project into production-ready tooling.
