Here's what's under the hood:</p> <p>⚡ The Core Problem<br> How do you route 105,000 fans to the right gate — instantly, without chaos?</p> <p>🧠 The Solution: Min-Heap Priority Queue<br> Instead of brute-forcing every gate option, I implemented a composite scoring algorithm:</p> <p>score = queue_length / throughput + α · distance</p> <p>→ O(N + k log N) time complexity<br> → Each routing query: ~O(log 20) ≈ constant time<br> → Full rebalance of 105K users: ~450,000 ops in &lt; 50ms</p> <p>That's not a guess — that's math.</p> <p>🏗️ Full-Stack, Production-Grade<br> • Python Flask + WebSockets backend<br> • React 19 + Tailwind CSS 4 frontend<br> • Google Gemini AI for the fan assistant &amp; crowd context<br> • Dual persistence: Redis → falls back to local JSON automatically<br> • Google Maps API with Haversine fallback for zero-downtime routing</p> <p>🤖 AI-Powered<br> Every chat query injects live crowd context into Gemini — so fans get answers that actually reflect what's happening in the venue right now.</p> <p>📍 The UX Insight<br> I used cardinal directions (N/S/E/W) as spatial anchors — because fans already think this way inside a circular stadium. Reduced time-to-decision without a single extra click.</p> <p>Building this taught me that the right data structure isn't a detail — it's the whole product.</p> <p>link : <a href="https://venueflow-service-1015826998904.us-central1.run.app/" rel="noopener noreferrer">https://venueflow-service-1015826998904.us-central1.run.app/</a></p> ai programming devchallenge
