Not sure if you want this feedback or not. You sound vastly more qualified than a current team member who is contracting for us.

Reading your statement I don’t hear anything about what you have done for other people. Instead of saying I open sources projects, say my open sourced projected were used by X many other people. Or I used my IT experience to cut downtime by 50% so my coworkers didn’t have to come in on the weekends. Maybe tell us why the non trivial code made your iOS app more successful.
