I have never done any kind of commercial software, so I decided to try it out.

Probably the best way to do it would be to get a job doing programming, but despite having 2 degrees in computer science, programming for 15 years and a year of applying to hundreds of jobs I still couldn't get one.

So I just got a job stocking shelves in a grocery store for ~3 months to gather some capital and registered a limited liability company.

Personally I would have preferred doing a desktop app, but since they are not popular anymore, I made a SaaS.

Since I had just finished working on a raytracing renderer for my graphics package, I decided to make a bingus-my-beloved style image generator.

Basically I just save the list of operations needed to compute each pixel color of an image, instead of executing the operations immediately. Then I convert it into a bytecode-like format and store it. When generating images I just execute the bytecode to generate the final color values for each pixel in an image.

I also used Google Cloud! (I have never used a cloud before and I heard that it is a good cloud).

Personally I don't really like doing frontend and CSS, so I minimized my use of it via arcane <table> magic that I discovered on StackOverflow 15 years ago. At least it renders correctly in Internet Explorer 6.

Most SaaS project don't really generate any revenue, since they solve problems that don't exist, so I would not be upset if this project flops.
