Hi, Tuchar,
I've checked your requirements and found that this is similar to a project I did a few months ago - Backend development on the ADL Canvas, a TT Visual programming language.
I can start your project right away and fully implement the project details.
Since the level of complexity of the project is said to be low, I believe it can be completed in one week.
It would be very interesting to chat with me about the details of the project, so please send me a message.
Thanks.
