A stock screener sounds simple until you build one. The data is messy. Tickers change. Splits and dividends break your history. APIs rate-limit you at the worst time. I have hit every one of these problems before, so you do not pay me to learn them on your project.

What you get

• Technical filters: RSI, EMA/SMA crossovers, MACD, volume spikes, candlestick patterns.
• Fundamental filters: P/E, market cap, dividend yield, earnings dates.
• Real-time or end-of-day data, depending on your budget and data source.
• Watchlists, saved screens, custom scoring, and CSV export.
• Deployed on AWS or GCP with scheduled data updates.
