I am a seasoned software developer specializing in trading algorithms and analytics. As the founder of Statistical Edge Ltd, I lead the development of cutting-edge optimization tools that revolutionize trading strategies for our clients. My technical prowess spans Rust, C#, Python & Pinescript, with a large portfolio of contributions in tradingviews pinescript, including an Editor’s Pick script (ask for more info). While I have extensive experience in creating thousands of Pinescripts, my current focus is on integrating AI with trading algorithms to develop high probability and profitable trading algos. If you’re looking to enhance your trading performance with advanced, bespoke analytics and optimizations, I’m here to deliver results that drive success. Let’s connect and explore how my tailored solutions can elevate your trading strategies.

I’m a developer experienced in building automated trading systems and custom financial bots for professional traders and fund managers. Whether you’re trying to eliminate emotional trading, integrate complex AI algorithms, or bridge your technical strategies across platforms, I can help. Expert in Python, MetaTrader 5 (MQL5), TradingView (Pine Script), VPS and System Automation. End-to-end bot development from strategy logic backtesting to 24/7 live execution. Risk management focused, ensuring strict drawdown controls and bulletproof code. Precise execution and regular communication are important to me, so let’s get in touch to automate your edge.

I build and run automated trading systems — and I trade them with real capital. My day-to-day is live algorithmic strategies on futures (MNQ/NQ) through a TradingView → TradersPost → Tradovate API pipeline, which means multi-source data integration, webhook execution, and risk-managed automation are things I do in production, not in theory. What sets me apart on trading and market-data projects: most developers who take them on have never placed a trade. I have. So I understand the non-fundamental signals that actually move price — volume, market-profile structure, order flow, and sentiment — and I can tell the difference between signal and noise. I work in Python and integrate LLM and market-data APIs to turn raw data into structured, decision-ready output. I'm rigorous about validation: I evaluate systems with backtest capture rates, win-rate / profit-factor, and Monte Carlo ruin-rate analysis, so what I deliver gets stress-tested rather than just demoed. If you need someone who can both build the data and analysis plumbing and judge whether the output makes sense from a trader's perspective, that intersection is exactly where I work.

I run a live multi-asset CTA system — 8 instruments across FX and metals, deployed on AWS, monitored 24/7. I don't just code trading systems. I operate one. That means when you hire me, you're working with someone who knows the difference between a strategy that looks great in backtest and one that survives live execution. I've built a 7-layer anti-overfitting framework (nested walk-forward, CPCV, Monte Carlo permutation, Bonferroni correction, structural break detection) because I learned the hard way that most "profitable" backtests are curve-fitted noise. Client work on Upwork: 2 projects, both 5.0★, both delivered on time. Built TradeGuard — a Chrome extension that intercepts trader behavior on TradingView in real-time. Client came back within the same week for a second project and left a bonus. His words: "perfect, thank you." What I build: → TradingView / Pine Script — custom indicators, strategies, alerts, webhook automation to broker execution → MT5 Expert Advisors — strategy automation, risk management, multi-symbol EA architecture, Python-MT5 API bridge → Python trading systems — backtesting engines, data pipelines, signal generation, portfolio-level risk management → AI-powered trading tools — Claude/GPT integration for trade journaling, market analysis automation, behavioral coaching → Chrome extensions for trading platforms — overlays, interceptors, session tracking, behavioral friction tools → n8n/Make .com automation — webhook routing, alerting, monitoring pipelines I also run 14 production automation workflows on self-hosted infrastructure and won 1st place in my university's Innovation & Entrepreneurship Competition for an AI trading coaching platform. Process: I confirm requirements before building, deliver a working first version in 2-3 days, and iterate based on your feedback. I respond within 4 hours.

I’m a Full Stack and AI Workflow Developer with hands-on experience building scalable, intelligent systems for fast-moving startups and founders.
