I run a dev community. Finding events and speakers was chaos.
So I built DevTalkPlanet.com in 200 hours:

• Backend (my zone)
• Modern Frontend (new skills)
• User features: event listing, search, filters
• Speaker tools: Q&A, live polls, QR codes
• Organizer tools: event forms, banner generator

Now: 60 events, 100+ monthly users, growing organically.
Free and open-source.

We'll use it live during this talk.
Real commits, real learning, real product solving a real problem.
