I built this small corner of the web to keep the things I genuinely learn: programming-contest ideas, course notes, experiments, and the occasional thought worth returning to.
It is not meant to make my GitHub look busier. The useful part comes first; the presentation follows.
Real learning → real accumulation → systematic notes → something worth sharing.
What will appear here
Most entries will begin with problems I have actually encountered. Some may become polished explanations; others will stay as concise field notes.
For now, the direction is simple: algorithms, data science, computer science, and whatever I find interesting along the way.
