Cover image for I work in the railway

I work in the railway industry by day — and build fintech tools by night. 🚂📈 I just launched a new Fiverr gig: a custom Options Flow Dashboard that shows real-time put/call volume, price overlay, and key stats in a sleek dark interface. This came from my own experience trading US options (AAPL, SPY, GGAL on BYMA) and needing a tool that actually shows market flow — not just price. My existing portfolio already includes: ✅ OptionsGuru — Black-Scholes + Greeks + AI chat ✅ CCL Radar — real-time ADR gap monitor ✅ BotSignal Latam — algo trading signals And now this dashboard is available for traders and devs who want it custom-built. Starting at $50. Real data via Polygon.io (http://Polygon.io) available. #fintech #freelance #optionstrading #tradingdashboard #buildinpublic
