The brief

Extend and stabilize a live Futures & Options data analytics SaaS platform to production-grade quality — adding multi-broker order execution (AngelOne + Shoonya), real-time straddle charting with technical indicators, TradingView chart integration with live data feeds, PhonePe payment processing, and migrate the entire infrastructure to AWS EKS with autoscaling and observability.

What we built

A full-featured Futures & Options analytics and trading platform called "Trading Plus." Built from an existing codebase (maintained/extended by Antino), the platform comprises:

  • multi-broker order execution engine supporting AngelOne and Shoonya for F&O and equity orders with stop-loss, modify, cancel, and basket order workflows
  • real-time options chain with live socket streaming, encrypted payloads, and sub-second LTP updates
  • rolling straddle and multi-leg straddle charts with SMA/EMA/VWAP indicators powered by Highcharts
  • TradingView advanced chart integration with custom 1-min OHLCV datafeed
  • F&O strategy builder and options simulator with Greeks and IV
  • PhonePe payment gateway with async BullMQ webhook processing and invoice generation
  • SaaS subscription management with admin dashboard, CSV exports, and coupon system
  • full AWS EKS migration with Terraform IaC, autoscaling, Prometheus/Grafana monitoring; and
  • backtesting engine HLD/LLD design. The platform targets retail F&O traders and competes with Sensibull, StockMock, and iChart.
⊛ Live in production

Production deployment of: multi-broker F&O order execution (place/modify/cancel/SL) for NIFTY, BANKNIFTY, MIDCPNIFTY, SENSEX and stocks across NFO and BFO exchanges; basket order management with margin estimation; live option chain with encrypted socket streaming; rolling straddle and multi-leg straddle charts with SMA/EMA/VWAP; TradingView advanced chart with 1-min live datafeed; PhonePe subscription payments with coupon codes; admin dashboard with subscriber/transaction CSV exports; and AWS EKS-hosted microservices with Prometheus/Grafana monitoring.
