Maintain PaymentsHub framework such that added new features does not affect internal Intuit apps, GoPayment and QuickBooks mobile.
Fix and keep track of reported framework issues or bugs using JIRA board in Agile environment.
Make architectural decisions of the new module to ensure maximum reusability of the code inside the framework, while ensuring minimum complexity.
Migration of entire third party PaymentsHub to new repository dedicated for third party partners only.
Removed extra dependencies of other frameworks from PaymentsHub SDK making it easier to be consumed by third party partners.
Write Integration Tests for each new API added into the framework such that all Jenkins jobs builds properly, and features are tested with appropriate test cases.
Communicate and gather requirements from Intuit partners, design and build features for them inside PaymentsHub framework.
