Thanks for the suggestion. I'll try to learn more so that I can read what your code does. I'm also interested in backend development, but I want to know a bit about front-end development since I want to build a personal project in the future, and I doubt I can actually do that without knowing a bit about HTML, CSS, JavaScript, and so on. Regarding other open-source crypto exchange software, afaik there is OpenCEX, but I think they're not focusing on privacy since they support KYC.
