Problem

During a 48-hour hackathon at Hetch, our team lacked a clear direction after exploring ideas that felt low-energy and not unique.

Solution

During lunch and some brainstorming we pivoted to Rank A Plank, a competitive planking app with a timer, basic camera anti-cheat, leaderboards, and user profiles, prioritizing speed, usability, and immediate social engagement.

Role

Co-creator and developer responsible for ideation, rapid pivoting, core functionality (timer, leaderboard logic, profile system).

Outcomes

Built and presented a functional prototype within hours, generated strong social traction during the event, and got a large part of the hackathon lobby actively participating. The project was later paused after the event.

Lessons Learned

  • Momentum beats overthinking; the best idea came from spontaneity, not strategy.
  • Social energy can matter more than technical depth in short-format projects.
  • Shipping fast creates excitement, while perfection can kill momentum.
  • Not every project needs to scale; some are valuable for experience and exposure.
