LeetCoding

Less about grinding count, more about pattern fluency. I track which categories I'm slow on - DP transitions, monotonic stacks, range queries - and bias practice toward those rather than whatever feels easy. The live stats are partly to keep me honest. To keep my friends and me honest too, I built Streak Wars - a quick Telegram bot that tracks our LeetCode streaks and nudges whoever's slipping. The longer I do it, the less it feels like prep and the more it feels like a small daily warm-up for thinking precisely.
