As a Xero Bi-directional sync developer, I have great experience in unioning two datasets in two different systems to behave as one while leaving the databases to exist as different datasets/databases, when clients want to have different tools or different systems for accomplishing different functions on the same data set, like a system for taking and managing orders and a different system for customer support. Also, instead, I can create a suite which supports both functions and has a shared database. Though, using Xero bi-directional sync to share the dataset will enable to use both systems while maintaining a consistent real time view of the data in both systems. Also, I use Xero bi-directional sync to optimize processes, have the data representations be much closer to reality in both systems, and reduce the compound cost of having to manually address the inconsistencies or lack of data or the impact to the business. The use of bi-directional sync makes flexibility to add and remove systems, sometimes even multiple systems that sub-specialize inside a domain like storage, CRM, or ERP. The initial templates that I use are for Salesforce to Salesforce integration, but can be modified to be Salesforce to X or X to Salesforce. I am responsible to: -Translate functional requirements into technical requirements -Design and build high-performance, reusable, and reliable Apex code with best practices -Ensure the best possible quality of the application -Identify bugs and align with requirements during debugging -Write test classes for the class that you develop -Test bug fixes to make sure they work as per requirements, then deploy them to production.
