Freelance Full-stack developer with expertise in strucchange R-package, Github and Stackoverflow

Upwork – Posted by EnterpriseTalentSolutions Anywhere

Job Description

**********These are firm skill sets requested by the client. Please do not apply unless you have background in all three of the following: strucchange R-package, Github and Stackoverflow ****************

Who’s the client? Fortune 500 company founded in US but has global presence. Worlds largest manufacturer of consumer and personal care goods.
Who the Clients looking for: We need a ‘Full-stack developer’ having high experience in strucchange R-package, Github, Oracle DB (any standard DB if not Oracle), R-algorithms , Plotly/any data-series visualisation process, UI development. You should have capability to handle million of data-series and use them to interpret and provide filtered displays.

Needs: To further tune “strucchange R-package” (some basic code is available that works on a small data-series) to detect structural changes and early warnings of structural changes on a time-series (example of a data series attached: ) and materialize it into:
Graph that visualizes all structural changes and “systems between them” as well as early warnings of structural changes (currently we use Plotly chart ):

Meta-data stored in an indexed database about all structural changes and systems between them and early warnings. Currently we store the meta-data in a memory.
We need to run the tuned algorithm on 1,000.000+ data-series and capture all results in the database.

We need to create a simple page to filter and view the filtered data-series and their graphs instantly on a simple UI (filtering to be done using the meta data – hence we assume indexing in the database is required.)

We do have the basic code that is already developed and you will be given a handover to start working based on that code.

The code by you needs to be scalable as this algorithm will run on a million data-series.

For Github experience, you need to be very conversant with opensource platforms, opensource libraries etc.

We are open to any other chart than Plotly but you need to provide suggestions and that charting system needs to work atleast like Plotly

This algorithm will be run one time at first but later on needs to have a batch process run it (you would need to suggest some scripting to do it)

We are very particular with high end metadata handling and graph requirements

You should have good communication capability (soft skills) and be in a timezone closer to or in the European timezone.

The sample format, currently used Plotly charts, Metadata sample and the desired UI are attached as a single zip

How to Apply

If interested, please send email to: [email protected] along with a few examples of past work using the requirements ( Oracle, Strucchange, etc) above. We will discuss the next steps once we begin talking.
