Case Study Body / Story (Copy & Paste) Overview Traditional sports bettors lose edge to bookmaker margins and slow reaction times. VigX was engineered to solve this inefficiency by providing automated, real-time quantitative analytics that instantly compare soft bookmaker lines against Pinnacle's sharp baseline, surfacing high-probability expected value (+EV) opportunities for Counter-Strike 2, League of Legends, and Dota 2.

The Challenge & Objectives Building a live-odds analytics engine introduces heavy technical constraints:

API Rate Limits & Latency: Frequent polling of external odds providers can easily burn quotas and trigger throttling or 429 errors.

Hobby Hosting Limitations: Managing automated cron execution within serverless limits without forcing a costly infrastructure jump.

User Engagement: Creating an instantly readable, high-performance UI that removes clutter and gives professional and amateur bettors actionable data immediately.

Solution & Architecture Server-Side Caching & Polling: Implemented a robust snapshot store (src/lib/opportunities/cache.ts) backed by automated polling routes. This caches incoming odds snapshots so user page loads are instantaneous while background updates keep data fresh.

Sharp Baseline De-Vigging: Built mathematical processing routines using multiplicative de-vig formulas to strip bookmaker margins and isolate true fair probabilities, expected values, and optimal stake distributions (Kelly Criterion).

Frictionless Monetization: Integrated Whop checkout flows with a configured 14-day free trial, routing users seamlessly from the web dashboard to active subscriptions.

Results & Impact Successfully deployed a high-performance Progressive Web App featuring live market feeds, alert engines, and integrated bankroll monitoring tools (Hawkeye Bank Monitor).

Established a production-ready, scalable SaaS foundation capable of handling real-time data streaming efficiently.
