Projects
Personal builds and tools, including this website and the LeetCode progress tracker.
Hi, I'm Jhon Christian Rozano. I build to understand, study to deepen, and write to remember.
This site is a public notebook of my becoming, a place for code, data science, and the projects I continue to build. It is less a finished portfolio than a living record of curiosity, discipline, and progress.
