About

👔 An experienced manager in Product - Management, Design and Strategy.
🔬 A specialist in Business Intelligence, App & Web Analytics - BigQuery, more or less traditional data warehouses, ETLs, API connections, Firebase, GA4, Appsflyer, etc.

I spent over ten years in specialist and management roles in market research and digital agencies. Then switched to a career as an individual consultant. Working with and learning from companies large and small, global and local. A few things I recall fondly from that time:

🚀 A two-year modernization of Audioteka.com from a marketplace to an online service model, a complete transformation of the organizational structure, business assets and technology, which initially led to break-even and then significantly improved all key business metrics and increased the growth rate. I was the lead strategist in this process, with a colossal contribution from the CEO's vision, of course.
💰 Wyborcza.pl paywall redesign, a then innovative project that created a market benchmark for the efficiency of paid content distribution. I consulted, designed the concept, and then helped integrate the business results into the company's tech stack by coaching the development team or hacking some more resistant things myself. Finally, I helped build a tracking framework for the whole thing.
💪 Founding of DELIeVERS, a team of my longtime friends and colleagues in many projects, the best people in their respective fields I have ever worked with.
🔎 Relentless development and reinvention of product value in Sotrender.com, a leading Polish social media analytics tool, where I worked as a product strategy consultant and occasional UX designer.
🤯 Reviewing 15 years of behavior of over 2.5 million users of GoldenLine.pl, with extensive use of cohort analysis, which required upgrading my desktop PC to provide enough power for the R scripts.
💻 Programming VisDynamica (a Delphi desktop application with a server component) - a free rapid visual prototyping tool based on Microsoft Visio that was used by nearly 5,000 professionals from 136 countries, years before the wonderful tools like Figma even existed.
