I have little experience in development (although I work in tech) and I was hoping to get some recommendations from the Gitgub community on what software programs for a personal project. Looking to build a mobile app and a website that connect to a database to run a scheduling engine. I expect at most10k users simultaneously using the software . I would like the user interface of the app and the website to be similar to the look and responsiveness of TurboTax and Calendly and I was told that Ruby on rails would be the best place to start. I also was told Node might be helpful. Thanks so much for any direction you can provide. I really appreciate it.
