How are you? I am looking for a front end developer to help with some coding. We are working on Android app only at the moment and its mostly in Java. Currently we are trying to change servers and have a more secure app since I am starting with new developers. I have learned that the previous devs left some databases open and they were hacked and deleted and so now I am starting with new eyeballs on the project. I have a great backend dev named Cassandra, she's awesome so far, just looking for someone to work with her, but on the front end. Would you be interested?
