No public demo — it moves real money, so there's no safe login to hand out.

Ask me for a walkthrough — the backtest → paper → live promotion funnel is the part I'm proudest of.
A quantitative trading platform that actually trades. It pulls seven market-data feeds, runs studies and backtests, then promotes a strategy through paper trading to live orders on Kraken — with drawdown halts, balance reconciliation, and a daily health digest. Runs in production on a server I manage.
- A strict promotion funnel — every strategy earns its way from backtest to paper trading to real capital, or gets cut. No strategy touches money it hasn't proven itself on.
- Real safety rails — drawdown halts, slippage caps, idempotent orders, and balance reconciliation that freezes trading the moment the books disagree with the exchange.
- Built to be watched — hand-drawn heatmaps, histograms, and parameter-grid sweeps with a live feed — all custom Stimulus, no charting library.
- Runs itself — minute-level data on cron, automated backups, a queue watchdog, and a daily health digest to Telegram, on a server I manage end to end.
