Wrote an automation script to create training sessions for the NHS on a new tool they were using.
We used to have to build six servers manually then install lots of software on them, and that meant errors were likely and caused issues.
I documented the manual process and turned it into code.
This meant when we needed to build a new training course the team just needed to run one command and their services would be set up in 3-4 hours.
Much quicker than before and no typos or errors.
