Honestly it's not that hard to design controllers. It simply requires a fundamental understanding of finite state machines. Amateur / rushed coders think the if else statement is cheap way to program in a ruleset and often end up with rare corner cases as a result. The key is to define your states, and don't ever let it ever get outside of what is expected. But if it does, make sure you can detect it and revert. This isn't rocket science. A raspberrypi is faster than computers 5 years ago, don't mistake it's price for quality.
