Project Portfolio

Selected engagements — anonymized — across financial services, manufacturing, AdTech, retail and FMCG.

A decade of work sits behind these. From boardroom strategy at BCG to production machine learning, the through-line is the same: frame the business question sharply, solve it rigorously, and ship something that moves the number.

Financial services · Strategy (BCG) Strategy for a leading Polish bank and a major European insurer

As part of BCG, I worked hands-on with client data, ran research and client interviews, and built the analyses and presentations behind strategic recommendations delivered to senior stakeholders.

Manufacturing · Advanced analytics (BCG) Efficiency optimization for one of the world’s largest brewers

I brought machine learning and advanced analytics into an operational optimization engagement for a global brewer — translating messy production data into measurable efficiency gains. Yes: I once optimized a brewery.

AdTech · ML & experimentation Real-time bidding systems for leading AdTech companies

I advised and built for AdTech leaders: machine-learning models that buy mobile display inventory in real time, paired with disciplined A/B testing and reinforcement-learning approaches. The brief was always the same — solutions that move profit, measurably.

Retail · Causal inference Marketing measurement & optimization for a top global retailer

I designed a framework to measure marketing-campaign effectiveness and optimize spend across channels — grounded in causal inference and proper experimentation rather than last-click guesswork, so the client could trust where the next dollar should go.

FMCG / Product · Analytics Forecasting, audits & decision support across product and FMCG teams

Demand forecasting, data audits and quality assurance, A/B-test design, and data-driven recommendations delivered straight to product and C-level stakeholders — plus training corporate teams in applied AI.
