Open-source projects
As a geek programmer, I often preferred creating a custom tool that would speed up doing a tedious task than performing it manually. Sometimes I ended up working for two days on a tool to automate a task that would otherwise take three hours of manual work… Although that wasn’t the optimal solution, I learned a lot by solving various complex issues.
I will try to refresh and collect my tools on this page for others to learn and maybe reuse.
