Professional path

My work is about what happens to an organization when AI stops being a curiosity and starts affecting decisions, processes, costs and people.

At WeNet Group (2023-2025), ultimately as Chief AI Officer, I was responsible for moving from AI experiments to strategy and processes that work every day. There I learned something you cannot read in reports: AI delivers results only when someone is accountable by name for quality, data, security and delivery. Without that, all you get is a series of pilots.

Since 2026 I have been co-building Mill AI, where I build companies designed from scratch to work with AI: shared processes, automation, AI agents and a repeatable way of launching new businesses. It is my current practice and a proving ground where I check every day what really works in AI and what only looks good.

From 2020 to 2023 I worked at Axpo Polska, the Polish subsidiary of a Swiss energy group. I was responsible for digital strategy and led a transformation program covering customer service and billing systems in a regulated company. From there I know the reality of such organizations first-hand: compliance, multiple stakeholders and the requirement of business continuity. Earlier (2014-2020) I led technology implementations for large organizations, including banks and insurers.

Preparation for board work

Executive MBA, Kozminski University - strategic and financial craft: reading a business from the owner's perspective, not the project's.

Professional Supervisory Board Program, Kozminski University - a program preparing for professional oversight: duties and accountability of a board member, the work of company bodies, the board-management relationship. Currently in progress.

How to verify

LinkedIn - public professional profile: roles, history, current context.

Mill AI - the company I co-build. You can see what we are actually building.

Confidential conversation - references, client names and project details are shared directly, not published on the site.

What I do not publish

I do not publish case studies with client names, confidential references or project details that require context. I do not run public service sales or an open booking calendar. In work with boards, management boards and owners, context and confidentiality come first.
