I build and debug automated trading strategies for NinjaTrader 8, cTrader, and TradingView — with a focus on strategies that behave correctly in live markets, not just in backtests. Because NinjaScript and cAlgo are both C#, I port strategies between NinjaTrader and cTrader cleanly, and convert Pine Script to either platform without losing the logic in translation. Recent work includes a NinjaTrader 8 opening-range breakout strategy using unmanaged orders: per-weekday parameter sets, split TP1/TP2 position legs, automatic break-even stop movement, configurable bar-close vs. touch entry confirmation, and full order-state tracking so partial fills and cancellations don't leave orphaned orders. Platforms: NinjaTrader 8 — NinjaScript strategies, indicators, add-ons (managed and unmanaged orders) cTrader — cBots and custom indicators in cAlgo TradingView — Pine Script v5/v6 strategies, indicators, screeners, alerts What I do: Convert strategies between all three platforms Build from your written rules or chart examples Fix strategies that backtest well but misbehave live — fill assumptions, repainting, session and timezone bugs Backtest, optimize, and walk-forward analysis with a written summary of what the numbers actually mean How I work: I confirm your entry and exit rules in writing before coding, so there's no guessing. You get commented source, a debug logging mode so you can verify behavior bar by bar, and revisions until it matches your spec. Send me your rules or existing script and I'll tell you honestly whether it's a good fit.

I engineer trading algorithms and financial analysis tools across TradingView, MetaTrader 5 & 4, NinjaTrader 8 & 7, and cTrader, crafting code for optimal strategy development and execution.

I see it constantly: founders deploying systems that print money in backtests—or launching tokens with massive hype—only to watch them collapse because their trading terminals lack a high-performance backend, or their smart contracts are structurally flawed. I solve this. As a Financial Systems Architect spanning Quantitative Finance and Web3, I build resilient, production-ready infrastructure. Whether it is a sub-millisecond Python execution vessel for a hedge fund or a secure, enterprise-grade dApp ecosystem for a token launch, I enforce absolute risk control. With deep experience in market infrastructure, I act as your hands-on Technical Partner: one single point of contact, strict engineering rigor, and zero guesswork. ━━━ 𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 ━━━ Algorithmic Trading & Execution Engines • Architecting institutional-grade automated systems natively across MT5 (MQL5) and TradingView (Pine Script v6). • Building sub-millisecond Python execution vessels, utilizing WebSockets and ZeroMQ to route signals instantly to the broker. • Trade lifecycle management: precise order chunking, slippage caps, and dynamic trailing logic.

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.
