Sergey Mastitsky

Trained to a PhD level, I have 20 years of experience in academic and industrial

sectors, where I used Statistics and cutting-edge Machine Learning to create new knowledge and deliver measurable business outcomes. My colleagues have repeatedly acknowledged my expertise in a wide range of modern data analysis and manipulation tools (e.g. R, Python and SQL), ability to clearly explain technical concepts to a layman, high attention to detail, friendliness and professional manner. I've also authored 40+ peer-reviewed scientific articles (including a paper in Nature) and 5 books on data analysis and visualisation.

As a Data Science consultant and freelancer, I provider a variety of services, including but not limited to:

- Deep and actionable, data-driven insights into your operational processes, customers, and products;

- Accurate models for customer lifetime value and churn to power value-based

acquisition and retention campaigns;

- Predictive applications to perform planning and optimisation tasks (revenue forecasting, budget allocation, recommender systems, preventive maintenance, etc.);

- Bespoke software development for data analysis and visualisation (e.g. interactive Shiny applications, APIs, etc.);

- Personnel training and upskilling in Data Science (including introductory sessions for executives and managers, and one-to-one coaching sessions).
