AI-Powered Skill Marketplace + Live Skill Battle Arena

Inspiration

Hiring today is broken—resumes are inflated, interviews are biased, and real skills are hard to verify. We wanted to build a system where people are judged by what they can do, not what they claim.

What it does

An AI-powered platform where users prove their skills through real challenges. It includes a Live Skill Battle Arena for head-to-head competitions, and an AI system that generates a Proof Score based on performance, speed, and problem-solving approach.

How we built it

Frontend: React (clean, minimal UI) Backend: Node.js + Express Real-time battles: Socket.io AI evaluation: GPT-based analysis for solutions Data: Challenge results, scores, and rankings stored for profiles

Challenges we ran into

Designing fair skill evaluation logic (not just correct/incorrect) Handling real-time sync in battles without lag Preventing cheating or copy-paste solutions Keeping the system simple for MVP within limited time

Accomplishments that we're proud of

Built a working real-time battle system Created a proof-based scoring concept instead of resumes Integrated AI to evaluate how users solve problems, not just results Delivered a focused MVP within hackathon constraints

What we learned

Real-time systems are harder than they look AI evaluation needs clear constraints to be useful Simplicity > overbuilding, especially under time pressure The idea is strong only if execution stays practical

What's next for AI-Powered Skill Marketplace + Live Skill Battle Arena

Improve AI scoring accuracy and fairness Add anti-cheat mechanisms (plagiarism + behavior tracking) Build a recruiter dashboard for direct hiring Expand beyond coding → design, analytics, and other skills Launch public tournaments to drive user growth
