Weergeven van Data met Back-end API

Beste freelancers,

Ik ben mede-oprichter van een start-up die een veilige front-end nodig heeft om onze gegevens aan onze klanten te tonen en back-end API om de gegevens aan de front-end weer te geven. Het werk zou tegen midden september voltooid moeten zijn. Mijn Nederlands is helaas nog niet goed gegaan, dus hieronder zijn de verdere project details in het Engels terug te vinden.

Ik zie graag een reactie tegemoet.

I am co-founder of a start-up that needs a secure front-end to display our data to our customers and back-end API to serve the data to the front-end. The work would need to be completed by mid-September.
 
Back end:
We currently have our data stored locally in a Microsoft SQL database which will probably be best transferred to AWS RDS or similar (we are open to suggestions). We then need to be able to pass this straightforward data to the front-end.
 
Front end:
The main part of the front-end will be fairly clean and simple. The page is designed to be used by staff with a range of technical ability and often on public-sector computers which are not high-spec. We have a prototype dashboard built using Shiny (a library/extension of R) which displays the data locally which will serve as the basis of the design although we would certainly welcome your design input. An anonymised version is attached for your information. The design needs to be simple and accessible.
 
One page will feature a simple select menu which allows users to choose organisations and the time period they wish to display on a time-series line chart. The organisations users can choose from the drop-down menu will be dependent on their login. Beneath the chart will be a sortable table displaying some data (again, this may only display a subset of data based on the user’s login credentials).
 
A second page will display two word-clouds (one relating to positive feedback and one relating to negative feedback about the organisation) and a sortable table.
 
The third page will be a sortable and searchable table of feedback relating to the user’s organisation and select other organisations based on their login credentials.
 
This secure set of three pages will need to be accessed from our company website which will also need to be built. This again will be simple page containing information about what we do, who we are etc. We do not need the functionality to accept payments.
 
Sadly, my Dutch is not yet good enough to discuss in detail so we will need a developer who is speaks English.
 
I look forward to hearing from you and discussing the project further.
