Project Description

Develop a first working prototype for a new site.

The site should be able to visualize Sales with nice charts and maps.

We want to have a first implementation of Style1, Mode1+2, see below.

The site should be styled in a modern business fashion. We're searching

for someone who can develop the project over the years.


The site-user provides TSV-Data from sales with predefined columns:

CustomerName, CustomerZIP, CustomerCountryCode, SalesRep, OrderID, OrderValue, OrderDate, OrderCategory

The data is then preprocessed and displayed in one of the following modes:

Style1: Geo/Map: Show Sales on a map (Germany + surrounding countries):

Mode1 # markers for single sales with info on map

Mode2 # colored areas (like [url removed, login to view]) on map

selectable metrics: TotalSalesValue, TotalSalesCount, TotalCustomerCount

pan/zoom: zoom in/out to see smaller/bigger regions: (country, state, county, town)

underlaying map can be seen through (transparency on colored layer)

Style2: Chart: Show data in charts - this is not part of current job

Development should be with Style2 in Mind. If Style1 is good, we will fund Style2 for sure.


- html, css3

- Python/Django, well structured code

- PostgreSQL as Database if needed

- select and use open source tools where possible (OpenStreetMap, Openlayers, [url removed, login to view] ...)

- source control on private github account (provided), checkin on a regular basis

- provide intermediate results, you'll get fast feedback


We're thinking of publishing the code on github. Write clean and structured.


You need to show examples of dynamic, python-based sites you developed. You should

be able to show public available python code you developed. Please provide some thoughts/links on

which framework/tools you would like to use.
