Real-Time
A modern stock market platform featuring real-time prices, interactive charts, AI-powered market insights, personalized watchlists, smart alerts and daily news summaries, designed to help investors monitor and analyze markets efficiently.
The problem
Retail investors often rely on multiple applications to track prices, read financial news, analyze charts and monitor watchlists. Constantly switching between platforms slows decision-making and makes it difficult to stay informed in fast-moving markets.
Approach
I built a unified stock market platform that combines live market data, advanced charting, AI-powered insights and personalized investing tools into a single experience. The application emphasizes speed, simplicity and automation, allowing users to monitor markets, discover opportunities and receive timely updates without leaving the platform.
Architecture
Built with Next.js and TypeScript using Better Auth for secure authentication and Inngest to automate background workflows such as news processing, notifications and scheduled market updates. Interactive financial charts provide rich market visualization while a modular architecture keeps market data, AI services and user preferences independent and scalable.
