Here are some links to web& mobile apps which are developed by me. 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, Twillio Api, QuickBlox, AWS and so on. I can also develop backend apis using PHP(Laravel, Codeigniter), NodeJS, Python, as well as 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 required functionality.
