Data Science Consultant with expertise in economics and time series analysis
I implement data science solutions for organizations across a range of industries through implementation of statistical analysis as well as more advanced machine learning methodologies.
My educational background is a Master’s degree in Economics from University College Cork, Ireland. As such, much of my work has been in the domain of business intelligence; i.e. using machine learning technologies to develop solutions to a wide range of business problems. I most frequently work with Python, R, and SQL.
My expertise includes
Classification and regression modelling of customer features to identify significant influencing factors on customer interest and sales.
Interpretable machine learning to identify Diverse Counterfactual Explanations, e.g. what changes in features would turn a non-buyer into a buyer?
Linear Mixed Effect Modelling with TensorFlow Probability to identify the impact of separate customer segments on overall sales data.
Time series forecasting of sales data using tools such as ARIMA and Prophet.
Use of Bayesian analysis to quantify effects of interventions, e.g. how do factors such as economic shifts or marketing campaigns affect customer interest for a product?
Are you working on a similar type of problem that you wish to discuss? If you feel that my expertise can be of help to you, feel free to e-mail me.
