I build the tools systematic traders actually need — and I understand markets, not just code.
I specialize in trading bots, strategy backtesting, market dashboards, and financial-data pipelines. My focus is the difference between a backtest that looks good and one that's real — the strategies I build come with honest statistics, not curve-fit fantasies.
- Trading bots & Expert Advisors (Python, MT5/MT4) with real risk controls — position sizing, daily-loss limits, prop-firm rules
- Strategy backtesting — survivorship-free, realistic costs, deflated-Sharpe / walk-forward screening
- Trading dashboards & data pipelines — Python · FastAPI · React
- AI automation & LLM integration (GPT / Claude / Gemini APIs) — document pipelines, scheduled jobs, workflow automation with verification built in
- pit-data-sample — a free, real-data sample of a survivorship-free, point-in-time NSE/BSE dataset: delisted names included, fundamentals stamped with their real announcement date, CA-adjusted total-return prices. Ships with a runnable notebook and a worked case study — the same vanilla value screen "earns" ~+4 pp/yr more once you let it cheat with survivorship + look-ahead bias. CC-BY 4.0.
- nse-factor-backtest — research-grade factor backtester with a pre-registered, one-shot held-out test that rejected its own strategy. Most repos show winners; this one shows the machinery.
- nse-fundamental-screener — ranks stocks by Magic Formula / Quality / Piotroski F-Score from primary balance-sheet data.
- kite-execution-pipeline — SEBI-compliant Zerodha execution layer: target-diff orders, limit-only, human-in-the-loop, 11 tests.
- quant-cockpit — real-time trading dashboard (live equity, positions, risk) in React + FastAPI.
The point-in-time reconstruction pipeline behind the data — bhavcopy + corporate actions + XBRL, ~29k filings across 1,300+ names — is proprietary. pit-data-sample is exactly what it produces; diff it against whatever you use today, or open an issue to have it measured on your own tickers.

I take freelance work in trading systems, backtesting, and market tooling. Tell me your strategy or idea and I'll tell you honestly whether it's buildable and how I'd test it.
