objectarx programming

I am looking for a freelancer with expert level experience in ObjectARX and AutoCAD to help me modify an existing c++ AutoCAD plugin. The ideal candidate should have a good understanding of technical issues and be familiar with the most recent AutoCAD versions and its corresponding APIs. I have attached the C++ code for autocad 2022 that needs to be modified. Specifically, the function ap_class_pt does not work properly. I am also interested in porting all of the attached code to work in progecad (intellicad). Thank you.
