Brand new Java Web Application with AWS and NoSQL DynamoDB - open to bidding

The goal of this project is to create a social network type web application with a few additional features that will make the application suitable for my client. The successful Freelancer would be required to write several classes of Java code to facilitate various pieces of functionality including profile creation, message posting, commenting, and so on. Mostly these are simple IO operations with no requirement to develop an GUI at this time. Experience with highly scalable applications, AWS, and NoSQL technologies is desired. The project will start of with some core functionality but has the potential to expand into an entire feature catalogue if the initial stages are completed successfully. Guidance will be given throughout by the leading application architect who designed the solution initially.
