Quantitative Developer | Algorithmic trading systems in Python for futures, forex, crypto and equities. TradingView/Pine Script automation, Interactive Brokers, Tradovate, Binance, FIX 4.4. Backtesting, risk controls, live deployment. ⭐ 5.0 rated | 0–4 hr response Most trading ideas never become systems. I build the part that does: your strategy logic turned into a bot that runs unattended, with a backtest you can trust, risk limits that can't be bypassed, and monitoring so you always know what it's doing. I'm a Quantitative Developer at a proprietary trading firm that has shipped 600+ algo trading systems for retail traders, prop desks and funds. On Upwork I take the same process to every build, whether it's a signal bot or a full execution stack. WHAT I BUILD ✅ Trading bots & execution engines — Python/Node.js, atomic bracket orders, idempotent order IDs, partial-fill handling, reconciliation with broker state, emergency flatten ✅ TradingView automation — Pine Script indicators and strategies; webhook-to-broker bridges that turn alerts into live orders with duplicate filtering and position sizing ✅ Broker & exchange integration — Interactive Brokers (TWS/Gateway), Tradovate, TradersPost, Alpaca, Binance, Bybit, Zerodha, Fyers, Upstox; REST, WebSocket and FIX 4.4 ✅ Futures & prop-firm automation — MNQ/NQ, ES, CL on funded and evaluation accounts: daily loss locks, trailing-drawdown tracking, flatten windows, consistency gates (Topstep, MyFundedFutures, Tradeify rules) ✅ Backtesting & validation — walk-forward, slippage and commission modelling, Monte Carlo, multiplicity-adjusted selection to separate real edge from overfitting ✅ Risk layers — per-trade dollar caps, daily lock that survives restarts, cross-account freeze, kill switch, sit-flat fail-safes, kept independent of the strategy code so a strategy bug can never produce a naked position ✅ Dashboards & alerts — real-time PnL, per-strategy attribution, Auto-Trade on/off, Telegram/Slack/Discord on every fill and anomaly STACK Python, Node.js, C++, React dashboards, PostgreSQL, Docker, Linux VPS HOW I WORK 1. Scope — written spec with every rule locked, hour bands, milestone plan 2. Validate — backtest or observer mode with alerts before any live order 3. Build — fixed-price milestones, each ending in a live demo before payment is released 4. Deploy — VPS with monitoring, runbook, full source handed over the same day 5. Support — defect fixes against written acceptance criteria; optional monthly retainer RECENT WORK • MNQ liquidity-sweep automation (ICT/SMC) on a prop-firm account — state-machine strategy engine, Risk Guardian, cockpit, VPS deployment. 5-star review. • FIX 4.4 order gateway — sequence recovery, locates, kill switch • Multi-broker execution & risk pipeline for a forex prop firm • Multiplicity-adjusted validation engine for systematic strategy discovery Send me the instrument, the strategy rules and your broker. I'll reply within hours with a scope and a path to live.
