Launching SellerRepublic.com: An automated repricing software for Amazon sellers

December 20, 2015

Seller Republic - Easy to use Amazon repricing software

We've finally launched SellerRepublic.com, a SaaS app that automatically reprices product listings of Amazon merchants.

We started the project about 5 months ago, while I was chatting with a friend of mine who has an e-commerce business and sells on Amazon himself. He had used Amazon repricers before and he wasn't happy with the ones he had tried (and he had tried about a dozen of them already), so he had been ...

Adding a Time Zone setting to your Django app

October 29, 2015

I'm currently working with a friend of mine on a Django app for Amazon sellers to automatically reprice their product listings.

This has been fixed by including a ---service-ports option to the docker-compose run command.

Below is a sample usage for one of my Django projects, EZ Price Alerts.

Using Docker and Docker Compose for local Django development (replacing virtualenv)

April 30, 2015

Before Docker came along, virtualenv was pretty much the tool of choice for Python developers as it allows you to separate package dependencies for different applications you're working on without having to create separate virtual machines for each one. It worked very well for me.
