Hello there,
I know how to implement the object oriented paradigm to develop UML diagrams because since my graduation as Business analyst in 2015 i have worked a lot of projet like that.
So I'am a data modeler, I master the UML paradigm and its diagrams such as : Use case, Sequence diagrams, Class diagram, activity diagram....Indeed to design your project, for design pattern it is esay for me to know which one you will need such as Factory, Singleton, Adapter, Proxy
I assure that I can satisfy you completely and want to have a long term collaboration with you and i will be glad to offer you my services, and i can negotiate everything you want.
Best Regards!
