Michal Polanowski, MBA, PhD's Linkedin Analytics

Entrepreneurial Head of Data Science with over 10 years of experience in Machine Learning and Data Science. I help companies build teams that deliver impactful and efficient AI solutions. Some examples include: ● Built and managed a team of 14 with 100% (11 people) of the SG team retained and 6 people have been with me for over 3.5 years ● Over 30 machine learning models developed, deployed, and maintained by 3 data scientists: (1) ~15% better AUC compared to competitors’ top risk models (A score) ; (2) ~4x increase in the whitelist size due to model improvements (A score) ● ~20%-60% decrease in the customer acquisition cost with big data models while also 10-25% more retained customers via A/B tests, advanced data analysis, and statistical models (while keeping the budget constant) ● At the same time, we reduced the Data Science team’s cost by 50% and 2x productivity while maintaining the same working hours. We did this via optimizations of VMs, creative data engineering, more efficient machine learning pipelines, better SQL code, and monitoring tools I get excited about opportunities where I can drive Data Science culture and truly make an impact. I love connecting with new people so don’t hesitate to send me a LinkedIn message and a connection request.
