ChartSense.trade
Full SaaS trading education platform built solo from zero to production. It supports real users and paid Stripe subscriptions, with paper trading, live market data, AI-assisted journaling via OpenAI, 24/7 automated monitoring via Puppeteer, real-time charting, web push notifications, and transactional email. I designed and built the full backend, including auth, billing, cron jobs, and storage.
