Now as far as the data query engine, I can feel the pain of whoever tries to choose the best ORM out there. For the last few years there were a lot of efforts to abstract away anything related to databases (native sql, admin, internals etc) but all of them have serious limitations at the end of the day.
With Appteum we try to handle all of these pain points for you, so developers can focus on the business requirements they have in front of them.
Happy to hear what you plan to use Appteum for. Hop in our Discord and we can chat: https://discord.gg/8ETmPedepG
