Krystian Rdzonkowski
Currently working as a QA Tester, I am actively expanding my skills toward Frontend Development and Data Engineering. My main passion lies in web scraping and data processing. I love extracting valuable web data, structuring it, and transforming it into clean, user-friendly frontend interfaces that help others. This end-to-end workflow drives my continuous learning. Outside of code, I stay active through road cycling, tennis, and hiking. I am also deeply into photography – you can check out some of my favorite shots in the section below. Explore my development projects to see how I connect data with code!
