GDG × OpenAI Hack Node Australia — YOLO (Full-stack Upgrade)

Project Overview

Second Global AI Hackathon node in Australia. I rebuilt the AdventureX prototype into “YOLO·AU”: a growth-as-asset social app where every builder has a personal token (YOLO), and behavior generates GXP to unlock permissions and ranking. New modules include Growth Circles (community/DAO-like spaces), Missions (challenge engine), and a lightweight Scout dashboard for investors.

What I Built

• Designed growth primitives: personal YOLO token + GXP reputation; permission unlocks from GXP tiers.
• Implemented Circles (community spaces) with leaderboards and mock voting; Missions for weekly challenges.
• Shipped Scout console: watchlists, basic trend signals (GXP delta, token holder changes, task finish rate).
• Front-end in Next.js/React + Tailwind + Zustand; auth via email/username (Auth.js or mock).
• API in Go (Gin/Fiber) + PostgreSQL (via GORM/SQLC); Prisma alternative path documented for Node stack.
• Event timeline & assets: growth events (projects/awards) unify into a user ‘growth graph’ used by ranking.

Reflection

I treated “growth” as a first-class asset: actions mint reputation (GXP), support mints price signals (YOLO), and both feed discovery. Operations-wise I validated acquisition loops (missions + circles) and drafted anti-gaming limits (caps, daily GXP budget). This upgrade made the prototype coherent for early users (builders, scouts) and clarified a path from vibe hacking to a defensible product thesis.
