I build trading systems that survive live execution — not just backtesting. 27 years of C# development. 20+ NinjaTrader 8 indicators and strategies. 10+ MetaTrader 5 Expert Advisors. Python ML pipelines with walk-forward validation and ONNX deployment. PhD in Management Information Systems. Every system I deliver comes with full source code, documentation, and a walkthrough so you understand what I built and why. I'm a developer who understands trading, not a trader who learned to code. That difference matters when your strategy needs to handle partial fills, slippage on a fast NQ breakout, or a prop firm's trailing drawdown rules. WHAT I BUILD NinjaTrader 8 (NinjaScript/C#): Custom indicators (regime filters, order flow, harmonic patterns, composite dashboards), automated strategies (breakout, momentum, mean-reversion, institutional zone detection, volatility compression), advanced trade management (multi-target exits, ATR-scaled trailing, break-even, time-based exits, re-entry logic), full parameter exposure for Strategy Analyzer optimization, and data export pipelines for ML model training. MetaTrader 5 (MQL5): Expert Advisors for live and prop firm environments. Box breakout (6 versions), volatility compression straddle, Heiken Ashi exhaustion, multi-strategy EAs. Session filtering, spread guards, prop firm compliance (drawdown limits, daily loss caps, consistency rules, magic number management), and risk-based position sizing. Python ML Pipelines: XGBoost, LSTM, Transformer, and MLP models for session-type prediction, directional forecasting, and signal filtering. Walk-forward validation, SHAP explainability on every prediction, Monte Carlo stress testing (10,000 equity paths), and ONNX export for sub-millisecond inference inside NinjaTrader. Pine Script (TradingView): Multi-timeframe systems with non-repainting architecture, state-based logic, session-aware execution, and liquidity sweep / SFP detection. Cross-Platform: Strategy porting (NT8 ↔ MT5 ↔ ATAS ↔ DAS Trader ↔ Python), cross-platform signal routing across 5 simultaneous platforms, and broker API integration (Interactive Brokers TWS API, Rithmic, MetaTrader broker API). FLAGSHIP BUILD: IMBOne Cortex The most complex system in my portfolio — a quantitative trading intelligence platform I architected and built end-to-end as sole developer. WPF/.NET 9, 7 server projects, 30+ table MySQL database, SignalR real-time streaming, Redis caching layer. Core systems: real-time data engine processing 100K+ market data messages/min via Polygon WebSocket. Dark pool level detection (FINRA data, 4-tier classification). Gamma exposure engine (DIY from raw options chain data — zero vendor dependency). Pre-market scanner screening 8,000+ equities. ML pipeline with XGBoost classifiers (session-type F1=0.736, IB-direction F1=0.727), nightly automated retraining, SHAP explainability rendered in-app, and ONNX Runtime inference. 40+ engineered features. If I can build this solo, I can build what you need. SELECTED RESULTS ▸ Institutional Zone Breakout (NQ) — Sharpe 2.30, 53.9% WR, 668 trades ▸ ICT Liquidity Sweep — Sharpe 4.81, PF 1.93 ▸ Box Breakout EA (v6.5) — directional bias model, 82% AUC ▸ EURCHF ML Pipeline — walk-forward validated, mean Sharpe 4.02, all folds positive ▸ 80% Rule Debunk — 5+ years NQ data, measured 18.3% vs. claimed 80% ▸ Level Touch Probability — distance gravity model, AUC 0.78–0.85 ▸ NQ Breakout Pipeline — MBO-10 microstructure, absorption signal identification HOW I WORK Understand your strategy logic and goals before writing code Build clean, documented, configurable code — every parameter exposed Validate rigorously — walk-forward, Monte Carlo, statistical significance testing Deliver full source code + performance report + walkthrough session All client strategy code treated as confidential.

🏛️ 𝐀𝐥𝐩𝐡𝐚 𝐝𝐢𝐞𝐬 𝐢𝐧 𝐛𝐚𝐝 𝐢𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞. Brilliant quantitative logic is worthless if your execution architecture bleeds capital under live-market pressure. I see it constantly: founders deploying systems that print money in backtests, only to watch them collapse in production because their MT5 terminals or TradingView webhooks aren't properly bridged to a high-performance backend. I solve this. As a Quantitative Systems Architect, I build sub-millisecond Python execution vessels that turn fragile, isolated trading scripts into resilient, production-ready infrastructure. With deep experience in financial market infrastructure, I specialize in Project Rescue and Scale-Up Architecture. I act as your hands-on Technical Partner: one single point of contact, strict engineering rigor, and absolute risk control. ━━━ 𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 ━━━ Algorithmic Trading & Execution Engines Architecting institutional-grade automated systems natively across MT5 (MQL5) and TradingView (Pine Script v6).

Trade lifecycle management: precise order chunking, slippage caps, and dynamic trailing logic. Fintech SaaS & Prop Firm Infrastructure Designing high-concurrency B2B dashboards and server-side risk management microservices (Next.js, FastAPI, MetaApi). Enforcing strict Prop Firm drawdowns, daily loss locks, and automated equity syncing to protect capital from emotional trading. Bridging traditional frontend terminals (MT5/TV) with robust Python backends. Broker API & Data Pipelines Direct integration with Rithmic (R-API+), Binance, Bybit, and FIX protocols. Structuring historical MBO, tick-level, and order-book data ingestion pipelines (e.g., Databento) for accurate backtesting and ML-feature extraction. ━━━ 𝗪𝗛𝗬 𝗙𝗢𝗨𝗡𝗗𝗘𝗥𝗦 & 𝗤𝗨𝗔𝗡𝗧𝗦 𝗪𝗢𝗥𝗞 𝗪𝗜𝗧𝗛 𝗠𝗘 ━━━ I Understand Both Software Engineering and Quantitative Finance I speak your language. I don't just understand basic SL/TP; I understand Level 3 Order Books, Liquidity Voids, Lock-free Ring Buffers, and Structural Risk Validation. I don’t approximate your logic; I implement your mathematical models exactly as defined. Exact Logic, No Guesswork I build systems from the ground up with strict determinism. Every rule is coded, logged, and tested. If a condition is ambiguous, I clarify it before execution to ensure the system behaves 100% as expected under live-market stress. Zero Hand-Holding Required As your Fractional CTO, I don't just write code blindly.
