Hi There, I've just read your job post and much interested to built it like you want or need as I have been creating high quality and excellent iOS apps for 3+ years using Swift I'm expert in Geo-location, GPS tracking, Payment gateway integration, and Social media integration such as Facebook, Twitter and so on. I have good experiences in Firebase, Twilio API, AWS and so on. I can also develop backend APIs using PHP, as well as a web portal including admin panel. I've rich experiences to work with various 3rd-party services and APIs to integrate them into existing and new applications to extend the required functionality. The important thing is that I'll work in your time zone for good communication. If you choose me, you'll never be disappointed in me, and I'll do my best. Kindly reply to me so we can discuss more about it. Thanks
