Hi, I'm Zeyuan 👋

I make free, local-first developer tools — your data never leaves your machine:

  • 📗 LeetLog — auto-captures LeetCode practice (timing, submissions, accepted code) into Obsidian notes
  • 🌍 MeetSync — cross-timezone meeting scheduler
  • 📡 DDL Radar — CS conference deadline tracker

Your sponsorship funds store fees, maintenance, and upcoming features (AI-powered review summaries, spaced-repetition reminders). Every dollar goes back into keeping these tools free.
