I'm Błażej, a 22-year-old Computer Science student passionate about building complete, scalable applications. Starting with frontend development in 2018, I discovered my love for creating engaging user interfaces and expanded into fullstack development, now crafting end-to-end solutions focused on performance and user experience.

Currently, I'm expanding my expertise into mobile development, specifically iOS native development with SwiftUI and UIKit frameworks, exploring it as an exciting new direction in my career.

I've successfully delivered multiple commercial projects from concept to production, gaining comprehensive experience across the full software development lifecycle.
