Market Matchup

Market Matchup transforms stock market investing into an engaging, competitive social experience by enabling users to compete with friends in fantasy investment leagues that integrate real-time market data through financial APIs while providing social features, league management tools, and competitive rankings inspired by fantasy sports platforms. Built with React for a responsive frontend and Python or Node.js managing backend operations including API integrations, database management, and portfolio calculation algorithms, the application is production-deployed on Fly.io infrastructure and implements sophisticated features including real-time portfolio valuation updates, historical performance charting, league creation tools, competitive leaderboards, and transaction history tracking. The interface balances information density with usability through clear data visualizations, intuitive navigation patterns, and mobile-responsive layouts that ensure users can check portfolios and make trades from any device. This project demonstrates expertise across multiple technical domains—financial data integration, user authentication, database architecture for transaction records, real-time data processing, and social platform features—while showcasing product thinking that adapts fantasy sports mechanics to create an educational, entertaining gateway to financial markets that serves both entertainment and investment education objectives.
