Web Application Developer with Experience developing Amazon-related Software

I am looking for an experienced web application developer to build product forecasting software for my Amazon business. This will be a web application that will be used for my own purposes first, then later monetized - integrated with paypal or stripe and able to handle a large user base.

I would like to hire someone who has experience with building web applications used by Amazon businesses, specifically that integrate with Amazon MWS. This is not required for the position but highly recommended. If you have experience with a project like this, please mention it in your application and provide a link to the project if possible.

I am looking to hire someone long-term to add to my team to help with fixing bugs and adding features to my existing software. I also need someone who has the ability to develop google chrome extensions, as I often have these smaller projects developed to help with my business.

The position pays $400 for creation of the MVP (Minimum Value Proposition). This is regardless of how long the MVP takes - example: if you can complete it in 4 hours, you will still be paid the $400. The MVP consists of an application that can pull data from an Amazon account to view the following: ----------

After this, I'd like to pay $5/hour to fix bugs and/or add features, build other software, etc. I estimate ongoing work of roughly 10 hours/week (not guaranteed). If you do good work on this first project, I am likely to continue working with you, as I have other software I would like to have built.

Strong English and good communication skills are also required for the position. Let me know if you have any questions about the software and/or work relationship.
