About Jeffrey
Why you would hire me:
Do you want to have an accurate, useful forecast to help you plan your business purchases or hiring needs?
Do you have a difficult dataset, that needs a specialist to unlock the hidden seasonalities and trends?
Do you have complex needs from unreliable data, and need an expert to help you find the signal in the noise?
If your answer is yes to any of these, I am the freelancer for you!
My skills :
Cleaning and transforming your timeseries data to give the best chance for finding seasonalities and trends.
Handling missing data values, as well as outliers and low data volumes.
Develop and engineer the most useful features for forecasting the target variable.
Use all the most useful algorithms, combining them in ‘stacked’ algorithms and ensembles.
Panel forecasting for many different series together (e.g. forecasting sales of 20k different products for a business).
Understanding the difference between a business that needs a fast forecast with good accuracy, and one that needs the highest accuracy only.
Deliver your forecast in any format: Report, excel sheet, Dashboard, or local app.
I work with any timeseries data:
I can work with your CRM data, SAP data, Analytics data, Spreadsheet data, Marketing data, Logistics data, Sales data, or even Price-Action data.
About me:
I am a Data Scientist specialising in timeseries forecasting. I have a strong background in engineering, technical project management, and auditing. I offer a unique blend of analytical skills and global perspective to solve complex, business problems.
