Hey, Marcin here 👋
Product guy. Indie Hacker. AI Tinkerer.
Work
I work as a Product Owner for Core Engine team in Data Science Hub in Nestlé, where we build ML forecasting engine and deploy it across Europe.
Side Projects
I'm trying to find my way building saas tools and mobile apps, both solo and with my friends. Sometimes it goes well, more often I fail, but I learn along the way and enjoy the journey.
Hanzi Flow
HSK AI flashcards for Chinese learners.
The Agentic PM
AI tools for non-technical product managers.
I also built some Claude Code skills running Hanzi Flow's TikTok marketing on autopilot (mostly works).
