I have source code for a Android business process modelling app that was written in Python using the Kivy framework. I need to add additional functionality so that two or more Android tablets connected in a LAN environment can display the same model and any user can model and the changes are reflected on the other tablets in real time. Only one user must be able to model at a time, using some sort of locking mechanism. All I need is that additional functionality to be coded.
Dear Sir.
I'm talented mobile app/game developer.
I have been developing Android apps for several years. You can see high skilled apps in my portfolios.
I'm very interested in your job post involving these skills.
I have consistently delivered projects on time and under budget,
which has earned us many positive ratings, as you'll see in work history.
I believe that my skills would be ideal for your project.
I will be available 40 hours per week.
Regards, Jin.
