Software Development Engineer III

Responsibilities:

• Developed a global hybrid storage disaster recovery system to allow clients to store large amounts of customer data in the cloud. The architecture consisted of moving study object series for archival from an on premise storage access point to Amazon’s S3 and Glacier endpoints.
• Provided input in all phases of the SDLC by drawing detailed diagrams to explain the architecture and discussed implementation and deployment issues.
• Configured hybrid storage solution endpoints by creating HTML5 inputs, XML for reading and validating deserialized JSON data, creating an authentication service to generate a token for keys and schema data and Sql server for storing the data.
• Wrote detailed functional tests to verify the authentication token and notification service messages generated using a request message containing the authentication token, headers and body containing the study transaction information and test cases to verify storage of study series objects.
• Applied Agile TDD to test the notification service by writing test cases for submitting jobs using a Quartz scheduler, Postman request over http using Json to an Owin hosted storage access point service and receiving status of the job from the cloud endpoint over RabbitMq message queue, a Service locator, factory and StructureMap classes to register and instantiate services, Visual Studio and Sql Server.
• Wrote a client to test WCF service endpoints hosted in OWIN by specifying request header and body message to make a HTTP request and log and display the response message.
