I am mobile(Android and iOS) app developer working since last 6+ years.
I have good grip to read existing code and have good sense of UI/UX. I can integrate payment gateway(PayPal. Stripe, Braintree), Rest APIs and Web APIs development and integration. I can help you to enhance your existing app and to add new functions.
I have knowledge of source code control tools like : GIT, Jira, Bitbucket, SVN etc. I have experience with REST API integration and web service development and integration.
I will be available for interview and further project discussion on your time zone.
