Seven years inside Poland's largest retail network. The last three spent moving AI out of the slide deck and into 13,000 stores.
A replenishment engine measured at about 1% incremental turnover. A data product past PLN 100+M. An assistant that now answers most of the network's operational questions without a human ever picking up. Before all of it, six years running a fifteen-person software house with my own P&L.
I also co-authored the company's EU AI Act governance framework – shipping AI at this scale is only half the job.
Validated impact against 2,000 matched control stores before wider deployment, demonstrating approximately 1% incremental turnover. Custom LightGBM model on Azure.
Azure AI Search with OpenAI and Gemini models. Accuracy raised on a 100-question golden set by fixing input document quality and rethinking chunking. Self-reported saving of two hours per employee per month.
Rejected personal and HR data despite user demand – access-control and integration cost outweighed the benefit. Scoped the assistant to non-sensitive content instead.
Balanced pressure for a faster rollout against the risk of unreliable answers by introducing golden-set evaluation before scaling – measurable answer quality, not stakeholder perception, as the basis for product decisions.
Defined the commercial model, the pricing and the data-privacy boundaries together with Legal and the Commercial Department.
Changed the design after discovery with franchisees showed full automation was not the right target for every scenario. Reframed the product around selective self-service, clear conversation boundaries and escalation to a human.
Also delivered – a marketing content generation suite (video, copy, comms) · document intelligence over 60,000 store lease contracts · a customer-feedback insight tool processing 300K+ items a month · an HR tool for individual development plans, 500+ users.
Evidence before scale.
Golden sets, matched control groups, 100+ interviews with store staff and franchisees. Measured answer quality beats stakeholder conviction every time.
Governance as product work.
Co-designed the enterprise framework covering 70+ AI systems: EU AI Act risk classification and mandatory pre-deployment checks for data lineage, evaluation and human oversight.
Three teams, one AI Product Manager.
15+ engineers and 3 PMs today. Earlier, an enterprise rollout across 10 countries and 25 stakeholder groups – and a P&L of my own for six years.
Business outcome over feature output.
Scope is judged by what it moves – incremental turnover measured against 2,000 control stores, a data product built from zero with 60 FMCG partners, and features dropped where the integration cost outweighed the benefit.

A senior product role where AI is the product, not a feature request – B2B or B2C, ideally with a real user base and a measurable P&L line. Comfortable being the person who says no to scale before the evidence is in. Remote or hybrid from Poznań.
Four online stores launched to PLN 200k+ turnover in four months. A five-person team across development, content and performance marketing; reporting rebuilt around CAC and LTV.
A corporate portal delivered across 10 countries in LATAM and EMEA for 10K+ users, coordinating 25 local stakeholder groups and the regulatory review path in a validated pharma environment.
Brand strategy built and executed; a loyalty programme that cut client churn by 8%.
