I am sure I can add match setting boxes and connect button in your ios and android app within short timeline.
As a professional iOS, Android app developer with more than 5+ years experience, I have high skills in iOS/Android app development and mastered at app developing tools and backend such as Firebase, backendless etc.
And I have used back-end integration with REST service as well as direct DB calls, Geo location, Geo fencing, Payment integration, facebook/twitter/instagram, and lot of other technologies in my apps.
So I am sure I can deliver good product within correct deadline, if you hire me.
I value time & credit. I always keep what I promised. Also I know the most important things for our remote work. Please feel free to hire me to see my working style and the quality of my work. I always aim to maintain a long term relationship with my clients.
