My projects
This portfolio showcases a focused collection of projects that reflect my current capabilities, creative direction, and evolving vision. Each piece represents a real-world step forward — whether it’s developing an early-stage app, building foundational client work, launching a podcast, or experimenting with concepts that stretch beyond the ordinary.
The goal here isn’t volume — it’s intention. These are projects that have taught me, moved me, and built momentum toward what’s next.
Explore what I’ve made so far — and what I’m in the process of becoming.

01
Mindgenic AI - early stage startup
A chatbot that helps gen Z to cope with loneliness in Poland. The project got an EU grant. It was my first startup project where I was a founder and a product manager. The app launched with 90 downloads but didn't find a product market fit. This project matters as my first experience in the startup world.
02
HeartRenew App
Self-dating app that lets you connect with yourself not other people. Conceptualized the app structure, developed the user flow, and launched an MVP with 6 initial users for feedback and refinement. This project matters because it showed me that I can create products without team and extensive funding.


03
Mapa wsparcia
A map showcasing LGBTQ+ friendly psychologists and mental health specialists in Poland. I created the map in cooperation with an NGO Rainbow after storm. I prepared the map based on the provided design. This is my first project done for the client. The project has been delivered to the client.
