Web apps
SaaS products, AI tools, dashboards, marketplaces, and custom platforms.
I design and build
digital products.
I'm Mikołaj — a founder and developer who turns ideas into polished products people actually use.
Web apps, mobile apps, and websites — from product design and development to launch.
Built, shipped, and used.
I don't stop at mockups or code. I take products from an early idea to real people using them.
