🌟 Inspiration

The fantasy sports world is broken. Players are stuck switching between multiple apps - checking injury reports on Twitter, manually placing bets on PrizePicks, texting friends about picks, and tracking winnings on spreadsheets. We envisioned a unified ecosystem where your entire fantasy sports social experience lives in one intelligent, proactive platform.

DailyFan was born from the realization that PrizePicks had incredible gameplay mechanics but lacked the social fabric that makes fantasy sports truly engaging. We wanted to create the ultimate fantasy sports community - where AI doesn't just assist, but actively participates in your betting strategy.

🚀 What DailyFan Does

DailyFan transforms fantasy sports from a solitary activity into a collaborative, AI-enhanced community experience. Our platform combines:

🛠 How We Built This Beast

🏗 Architecture Overview

Frontend Stack:

• React Native + Expo Router (SDK 54, RN 0.81.4, React 19.1)
• Tamagui for consistent theming and component system
• Next.js 15 (App Router) for embedded web chat experience
• TypeScript throughout for type safety and developer experience

Backend Infrastructure:

• Server-Sent Events (SSE) for real-time chat synchronization
• In-memory chat hub with automatic connection pruning
• REST API architecture for bot integrations and user actions
• Zustand state management for seamless client-side state

AI Integration Layer:

• CedarOS Framework: Ambient AI components for enhanced user experience
• Perplexity API: Real-time sports news and injury intelligence
• Custom browser automation: Headless Chrome agents for PrizePicks interaction
• Natural language processing: Command parsing for betting instructions

🔧 Key Technical Innovations

Cross-Platform Bridge System:

// Seamless WebView communication between RN and Next.js
const resolveWebChatUrl = () => {
  // Priority: Override → LAN detection → Localhost fallback
  return expo.extra.chatWebUrl || derivedLanUrl || 'http://localhost:3000'
}

Real-Time Chat Architecture:

// SSE-based messaging with connection resilience
const groupStore = create((set, get) => ({
  connect: () => {
    const eventSource = new EventSource('/api/group/stream')
    eventSource.onmessage = (event) => {
      const data = JSON.parse(event.data)
      set(state => ({ messages: [...state.messages, data] }))
    }
  }
}))

Agentic Betting Pipeline:

// Natural language to bet execution
const processPokeBet = async (command: string) => {
  const intent = await parseNaturalLanguage(command)
  const browserAgent = await launchHeadlessChrome()
  await browserAgent.navigateTo('prizepicks.com')
  await browserAgent.placeBet(intent.player, intent.stat, intent.direction)
  return await browserAgent.confirmBet()
}

💪 Challenges We Conquered

1. PrizePicks UI Recreation

Challenge: Reverse-engineering PrizePicks' entire interface without access to their codebase.

Solution: Meticulous pixel-perfect recreation using React Native components, custom animations, and Tamagui theming system. We analyzed every interaction, transition, and visual element to create an authentic experience.

2. Cross-Platform State Synchronization

Challenge: Maintaining consistent state between React Native mobile app and Next.js web chat embedded in WebView.

Solution: Developed sophisticated WebView bridge with custom URL resolution, message passing protocols, and graceful fallback handling for different development environments.

3. Browser Automation for Betting

Challenge: Creating reliable, undetectable browser agents that can navigate PrizePicks and place real bets.

Solution: Built sophisticated headless Chrome automation with anti-detection measures, human-like interaction patterns, and robust error handling for dynamic UI elements.

4. Real-Time Performance at Scale

Challenge: Handling real-time updates for multiple users while maintaining sub-100ms response times.

Solution: Implemented Server-Sent Events with intelligent connection pooling, automatic reconnection, and optimized message broadcasting with connection pruning.

5. Natural Language Bet Processing

Challenge: Converting casual speech like "give me the over on LeBron" into precise betting actions.

Solution: Developed NLP pipeline using intent recognition, player name disambiguation, stat mapping, and context-aware parsing for betting terminology.
