Hi,
Quick intro: I haven't done freelancing recently due to usually I work fulltime, last as QA Manager. Due to some personal reasons for a while l'm focusing on freelancing for extra income while on a break from contract employment.
I have great experience with Android native apps testing, from planning testing, hands on testing, raising issues, improvements, analyzing user data and behavior all with the scope of delivering the highest quality possible for the user.
I will break down the tasks I plan to perform so you have an idea of my plan and thinking. (price for milestones is just an estimate)
Testing will be done on different android devices and android versions (5->latest) in order to get good coverage on different OS, devices size and specifications.
Once accepted I will follow up with some more detailed questions in order to better understand your app and scope.
