Location map of Apple stores


Developer and technical lead


The project aims to create a globally consistent “resource” locator with the Apple “look and feel” to effectively and efficiently point customers to the most appropriate resource location(s) to assist with the problem or situation they are trying to resolve. For example, product sales, break/fix service, training, network installation, etc. The locator will be fed data from a consolidated data source (MongoDB/Big-Data) with the same data elements and data filtering for each region and available across the world.
