Nobody mentions Monitoring. Ensure the beast is monitored, like staring with the basics, cpu, disk space and so on. Then all goes to version control. Then changes can not be done in production, you need cicd, just build one step at a time. Do not aim for perfection, just concentrate on having a framework(mentality) of continuous improvement. You been given the opportunity of testing all your skills in a thing that "works" (makes money), you just need to find the metrics of where the money comes from and how to maximise it. Pareto principle can be of help when making decisions.
