Build an Online Store

Hello, I am looking for a eCommerce Platform developed in Rails. There is already an existing wordpress- prototype of my development. The development has all the standard component of a eCommerce Platform, i.e. multi role user authentication, product listing and rating, product category management, location management by IP, and many more. The platform is supposed to be a two- sided commerce platform, meaning that we need to support vendor and buyer role. The development should use the standard popular ruby gems to handle these tasks. In terms of payment transaction, we are still not decided between shopify and braintree. This component will be left for last. In terms of visuals, a redesign is being done as we speak and will be implemented by me on top of the application to be build once the development is finished. All I need here is a standard bootstrap fronted with fontawesome icons. I am a developer myself and would actively participate in the development myself. It is of great importance to make this development agile, i.e. to have regular (daily) commits to a git repo including short progress updates and issue reports. Also, I work with relatively small milestones. I will only work with developers directly, meaning that I want all communication to happen directly between me and the developer himself. I will not work with large agencies. If you are interested, please send me an offer along with a short portfolio of your experiences as a developer and your last project. Also, a little git portfolio with some of your private projects would be recommended. Thanks!
