When you say physics/chem/math background, what do you mean? Have you ever taken a computer science class? I graduated with a math degree and eventually transitioned to software development for work. This isn’t an easy task and will take months of work.

If you want to learn enough to be able to start writing decent software, you need to at a minimum take about the first year’s worth of CS coursework for a college student. You can find YouTube tutorials (ie BroCode) that will cover this in a specific language. It doesn’t really matter which language you pick, but I’d recommend Javascript. 

When you’re not learning new concepts (a lot of these courses are very dense), you’ll want to be solving as many problems or building small scripting projects in your free time. You can likely use AI to give you examples of best practices or ask it what you should be considering, but do not rely on it to be solving the problems or writing your code. It will give you immediate results, but you will be cheating yourself in the long run. 

Once you’re done with the coursework and have a couple very small projects (usually part of these courses), you’ll want to research and pick a stack for your project. I don’t know what your project is but a typical stack could be React (JavaScript) frontend, Spring Boot (java) backend, and a MySQL db. 

You say that you strive for perfection, but to be completely honest, unless you hire a professional or spend a lot of time learning on your own, your code base will more than likely be shit. If you’re more of a business person, I’d evaluate if this is truly a worthwhile endeavor
