    Matthew Shultz

    Expert iOS / Android Developer

    United States - Tests: 5 - Portfolio: 2

    In the past several years I have built many Iphone and Android applications, with a focus on Maps, GIS, GPS, PUSH, and geospatial data as well as experience in information management and presentation. My core ability is complete engineering of mobile applications from the ground up, choosing appropriate database, logic, and UI technologies from the array of existing options. I have specialized knowledge in mobile sync and RESTful communicate with custom websites and existing social media datastores. I also have a good deal of experience building web applications (php-apache-mysql, ruby on rails) using Ajax, OOP, and Agile methodologies to build highly scalable websites, as well as design of technology infrastructure using cloud technologies (AWS, EC2, IrisCouch, etc) I architect and implement integrated mobile and server side solutions for projects involving mapping, GPS navigation, geospatial analysis, RFID, GIS, remote data collection, location aware API design or integration, offline functionality, and other custom location aware technologies. I am currently experiencing very high demand for my skills. Clients who find it challenging to pay my full hourly rate may wish to contract instead for a few hours of consulting or architecture design work. With a short time investment, I can add value by providing structure and direction towards building a solution the right way, rather than relying on uniformed design decisions of less experienced contractors. I can also assemble a team to fill the full needs of a given project as needed.
