Greetings,
I'll be glad to work on your project,
I'm a software architect, with a master degree in complexe software engeneering, UML diagrams are in the center of my studies and ability, so i'm really at ease with unified languages.
I'll provide you clean and optimal diagrams with all the OCL constraints and comments to avoid any ambiguous understanding.
I work on argoUML and Star UML but i have no problem discovering new modeling softwares.
Feel free to contact me and have a nice day.
