During the early days of computing in the 80s I got fedup of doing repetitive work every year for audit purposes.

So i picked up a dBase3 book read it and wrote my own code with no prior computer programming knowledge.
the bank did not have an IT dept then.

the programs worked fine and after i left the bank they continued to use it until year 2000 when the programs were rewritten by the IT dept using my templates for y2k compliance purposes.

i did hear from my ex coworkers that the IT dept said that the code was like spaghetti. 🤣
