Design and operate algorithmic trading systems for TradingView and Bybit. I build strategies in Pine Script v6, validated through in-sample/out-of-sample backtesting to avoid overfitting, then connect them to live execution via FastAPI webhook servers. Key work: - Developed multi-symbol trading systems combining Pine Script strategy logic with Python-based machine learning (XGBoost, LSTM) for signal validation - Ran IS/OOS backtests across 40+ symbols, evaluating strategies by Profit Factor and max drawdown rather than win rate alone - Built Bybit V5 API integration for automated order execution via TradingView alerts - Focus on non-repainting, production-ready logic that performs the same live as it does in backtest
