About this Gig
Hello! My name is Filipe.
I work as a quantitative trading systems engineer on NinjaTrader (NinjaScript), focused on building robust, testable strategies driven by real market performance.
I have over 7 years of experience and 10,000+ hours dedicated to developing algorithmic systems, strategy automation, and quantitative validation.
My work goes beyond simply coding ideas: I design complete systems based on consistent logic, risk management, and statistical validation.
I work with:
- Custom indicators and strategies in NinjaScript.
- Strategy automation with non-repainting logic.
- Risk management (position sizing, stops, exposure control).
- Advanced backtesting and parameter optimization.
- Multi-timeframe and multi-instrument structures.
- Live execution integration in NinjaTrader.
- Institutional-grade order flow logic.
- Robustness testing: Walk-Forward, Out-of-Sample (OOS), and Monte Carlo.
- Quantitative performance metrics (Profit Factor, Drawdown, Expectancy).
My goal is to transform trading rules into verifiable, repeatable systems ready for live deployment.
Send me your idea and lets structure your system professionally.
