Ivo S.

If you can get him to not see in terms of impossible, and he listens to you instead of boasting about his expert level in android studio, he could be a 5-Star android developer. He needs to listen and not expect you to spend hours testing apk after apk with the same exact bugs you already gave him a video of 5-times to watch it happen. Be careful with freelancer developers as the word “Expert” is used and they self-proclaim this. Test your app, test your source code, before you give away any money. These developers will rush you and try and force you into the app they wrote instead of the app you hired them to code. Once you pay them, you will never get your app, code, or refund. Ivo S. can develop in android, but he wasted an entire day for me in the process. If he learns to listen, and watch videos showing the bugs, he will be a 5-Start Android Developer and then can call himself an expert. If you do not understand code and need to hire an app coder, get yourself a project manager to manage it for you. Trust me, you will need one. Also, use the recruiter service on freelancer. If you do not know how to code and do not understand it, then you will need a recruiter and a project manager. It will be expensive, but worth the expense. One day he will be a 5-Star Expert.

good professional and serious

He was very helpful once we learned to work together.
