Rafał Stybliński
Software Engineer (C# .NET) | AI/ML Enthusiast | UX Designer
I combine solid backend engineering with user experience (UX), building intelligent and highly optimized digital tools.
01 / About Me
Hi! I am a software engineer specializing day to day in the C# .NET ecosystem.
My main growth focus is Artificial Intelligence and Machine Learning (AI/ML) – I have completed specialist courses in this field and I keep expanding those skills with genuine interest. In addition, thanks to postgraduate studies in User Experience (UX), I do not look at software only through the lens of code, but first and foremost through the lens of people. I know how to design interfaces that solve real problems.
I am also the founder and president of the Future Democracy Foundation (Fundacja Demokracja Przyszłości), where I try to combine systems thinking with work for society.
After hours I develop my own portfolio of niche, multilingual engineering tools. I use lightweight front-end technologies (Astro, React) and Programmatic SEO strategies, turning complex mathematics into easy-to-use web calculators.
