Jakub Hul

Software Developer

Flutter Mobile Apps — Android & iOS
Websites & Web Applications
Python Scripts & Automation
API Design & Integration

I specialize in building mobile applications with Flutter for Android and iOS, as well as websites and web platforms for businesses, backed by robust Python-based backends, scripts, and automation systems.

I approach projects as complete implementations, not isolated code tasks: understanding the problem, designing the app, website, or API architecture, delivering a usable product, and iterating based on results. My qualifications include INF.03 and INF.04 as a certified Programming Technician.
