  • used by 6K+ ZJU students.
  • proficiency in: Flutter, Mobile Development, Git.

My Contributions

  • Open-source contributor: 16 pull requests submitted, 16 merged — shipped user-facing
    improvements and bug fixes through upstream collaboration.
  • Community-facing impact: Published two release/feature posts that reached
    CC98 Top 10 (ZJU's campus forum), helping drive adoption
    and gather feedback:
  • Problem-driven development: Started from my own pain point, then iterated based on community issues and user research.

What is Celechron?

stars license release commits contributors

Celechron is a time-management and campus-utility app built for Zhejiang University (ZJU)
students, initiated by iotang and n0sig.
It originated as an SQTP project and provides an all-in-one experience for:

How I Got Involved

I was one of the early users of Celechron — I first installed it during the TestFlight beta stage.

  • I opened issue-10.
    At the time, I didn't have enough experience with the relevant tooling (and an earlier
    Flutter demo attempt didn't go well), so it remained unimplemented for a while.

    issue 10

  • Later, when the previous tool ical.top stopped working (because DingTalk removed the
    timetable page), I invested time to learn the toolchain (with AI assistance), built an
    initial working version, and iterated with maintainers to fix bugs during review.

Some Takeaways

  • Start from real, personal pain points and solve them end-to-end.
  • Address issues raised by the community.
  • Run lightweight user research and iterate features based on feedback.
