Found something helpful to send invoices from the backend. Give them a vote on product hunt so I can stop manually making bill.com invoices. https://www.producthunt.com/posts/invoice-buddy
Thank you! Glad you like it. Yes this is in a repo. Should be able to click through to it via several links in the post. Definitely a little bit of work to implement it given how brittle/bad my code and workflow are but it should be reusable.
In my past life I was an oceanographer at a consulting company. Essentially we wrote Matlab code that processed data we get from ocean and meteorological models. Many of these models, used by NOAA, are all written in Fortran. While most were well documented, one thing you could not get around is the use of parameters for these models ( think of global variables used everywhere) and a never ending game of go-to statements. I had to figure out how this one flood model worked... literally had to read 5,000 lines of Fortran. This is what we use to determine potential flood impact from hurricanes, today. Software written for oceanography is a whole other beast.
Actually, sorting out what your point is might be a good starting, erm, point. What's your threat model, what do you hope to protect / avoid / guarantee?
