Hackathons I've participated in and my submission demos.

• v0 Prompt to Production

  A global build week (Jan 31 - Feb 8, 2026) where builders ship real projects with v0 and compete for prizes. One week. Global hackathons. Real apps, real work.

  Built for @v0 Prompt to Production week, challenging myself to stay under the free $10 credits.
  
  Unexpectedly burned credits on UI library picks, env variables, pnpm lock mismatches – which could've been used to polish the experience.https://t.co/Epfy2hgb2k pic.twitter.com/p0uVOqCSkr
