Quantitative Engineer | Trading Algorithms, Pine Script | AI & Physics "I am a Quant Engineer who takes full ownership of trading algorithms..." "I translate complex mathematical models into high-performance Pine Script & AI solutions. I don't just write code; I engineer financial ecosystems based on physics, mathematical resonance, and robust statistical modeling. With over 8 years of experience in algorithmic trading, I specialize in transforming raw market data into autonomous, high-precision trading systems. My journey began in data science labs using Python (Colab, Pandas, TA-Lib) to analyze market behavior. However, I evolved to specialize in TradingView’s Pine Script (v5) to bridge the gap between complex analysis and real-time, lag-free execution. My approach to Systems Engineering and AI Integration is unique: I treat the market as a physical system governed by wave resonance and elasticity. I build algorithms that filter noise using "Auto-Geometry" and logical tunnels, ensuring that capital is protected before it is exposed to risk. My Core Value Proposition: From Data Science to Execution: I translate complex mathematical concepts (Standard Deviation, Linear Regression, Fibonacci Ratios) into clean, efficient Pine Script v5 code. Physics-Based Logic: Unlike standard indicators, my algorithms (like my proprietary "Genesis" logic) use "Parallel Engines" and "Time-Resonance" to align with organic market movements, reducing false signals. Full Automation Ecosystems: I don't stop at the chart. I integrate TradingView strategies directly with execution platforms like WunderTrading, Binance, and Hyperliquid, handling the full signal lifecycle (Entry, TP, SL, Trailing, and Emergency Exits). Non-Repainting Guarantee: I strictly code for real-time reliability. I use advanced security functions and bar-state logic to ensure backtest results match live performance. Technical Stack & Capabilities: Languages: Pine Script v5 (Expert), Python (Data Analysis background). TradingView Advanced: Arrays, Libraries, Request.Security (MTF), Custom Alert Messages (JSON). Automation: Webhook integration with WunderTrading, 3Commas, and direct Exchange APIs. Strategy Design: Trend Following, Mean Reversion, "Tunnel" Logic, and Multi-Timeframe (MTF) alignment. If you are looking for a developer who understands the physics of price and can build a system that allows you to sleep while it trades, let’s connect. I build legacy-grade code designed for longevity and peace of mind.
