My goal is always to exceed client expectations with scalable systems tailored to their unique needs.

In the AI era, writing the code is the easy part — architecting a trading system that survives real markets is the hard part. That's where I come in. I'm a Senior Quant Systems Architect and an active trader since 2012, with two decades in financial markets and software. I don't just build trading bots — I've lived the markets they run in: the gaps, the halts, the slippage and drawdowns that quietly blow up systems built by people who never traded. Whether you trade Forex, Stocks, or Crypto, I turn your manual strategy into a fully automated, risk-controlled, data-driven system. My Core Expertise Includes: - **Trading Platforms & Language Syntax**: MetaTrader 4 & 5 (MQL4/MQL5), TradingView (Pine Script), NinjaTrader (C#). - **Execution Engines & EA Architecture**: Building modular Expert Advisors (EAs), custom indicators, and automated order routing systems optimized for fast fill rates and minimal slippage. - **Quant Infrastructure & Data Pipelines**: Custom Python pipelines for historical market data ingestion (Databento, ThetaData), cleaning, and time-series database design (TimescaleDB, Clickhouse). - **Crypto & Exchange Integration**: High-frequency API bridges and WebSockets integration for major exchanges (Binance, Bybit, Coinbase Pro) with redundant rate-limit handling. - **Visual Analytics**: Interactive React-based dashboard charts (Lightweight Charts) connected to live WebSocket feeds for real-time strategy monitoring. Why Work With Me? - **Risk-First Architecture**: Hardcoded drawdown limits, dynamic position sizing, and circuit breakers designed to protect capital in fast-market conditions. - **Strict Confidentiality**: Your proprietary trading algorithms, logic, and intellectual property are protected under strict NDA and absolute confidentiality. - **Mathematical Backtesting Integrity**: Rigorous historical analysis using event-driven Python engines (Backtrader/custom engines) to prevent look-ahead bias and overfitting. - **High-Performance Code**: Low-overhead execution logic written in C#, C++, and optimized Python (Pandas/NumPy) for sub-millisecond local processing. Let's eliminate human emotion from your trading and let the code do the heavy lifting. Send me a message with your strategy or project details, and let's discuss how we can build a production-ready execution system.

I am a skilled Full Stack Web Developer specializing in MERN stack and Web3 technologies, delivering dynamic, responsive, and scalable web applications. I build both front-end and back-end systems, ensuring seamless user experiences and robust functionality for various web projects. On the Algorithmic Trading side, I have extensive experience in Python, pandas, and related libraries for creating efficient trading algorithms. My focus is on automating trading strategies and data analysis to help clients achieve precision in their trades. For Indicator Development, I specialize in MQL4, Pine Script, MetaTrader 4, and TradingView platforms. I craft custom indicators and trading tools that integrate seamlessly with these platforms, optimizing trading setups for individual traders and firms alike. Whether you need a full-featured web app, a sophisticated trading algorithm, or a custom trading indicator, I have the expertise to bring your ideas to life.

Most trading bots fail after deployment — not during backtesting. I build automated trading systems designed for real broker execution, not just strategy tester results. I build automated trading systems for MetaTrader 4/5, TradingView, and NinjaTrader. What I Deliver MT4/MT5 Expert Advisors Entry/exit logic, position sizing, drawdown controls, trailing stops, and spread filters. Delivered with backtesting reports and live demo validation before handoff. TradingView Pine Script v5 Custom indicators, strategy scripts, multi-timeframe analysis, and alert systems with repaint-free builds. TradingView to MT5 Webhook Automation Python execution bridges connecting TradingView alerts to live MT5 order execution. I handle broker-side specifics such as symbol naming, lot step restrictions, and reconnection logic that many setups miss. NinjaTrader Strategy Development NinjaScript (C#) automated strategies, including swing detection, bracket order systems, and multi-level pending order management. EA Debugging & MT4 → MT5 Conversion Most failed conversions were technically converted, but broke on live charts due to bar indexing, buffer structure, or alert timing differences between platforms. I fix the structure, not just the syntax. Pine Script Debugging & Optimization Repainting fixes, alert debugging, multi-timeframe synchronization issues, request.security() handling, and Pine Script v3/v4 → v5 migration. I diagnose structural problems, not just compilation errors. TradingView → MT5 Real-Time Execution Systems Webhook-based TradingView alert execution pipelines with Python bridges for live MT5 order routing, notifications, trade confirmations, duplicate-order prevention, and broker-side execution handling. Background I actively deploy, monitor, and work with automated trading systems in live broker environments. My experience operating these systems in real market conditions — including slippage, spread changes, execution delays, and broker-side behavior — helps me build automation that performs more reliably beyond clean backtests and simulated strategy tester results.

I build automated trading systems, Expert Advisors, and trading bots using Python, MT5 (MQL5), and TradingView Pine Script. If you need: • a TradingView indicator or strategy • an MT5 Expert Advisor • a Python trading bot connected to an exchange API I can turn your trading idea into a fully automated and tested system. Specialised in: - Custom Indicators & Strategies – TradingView (Pine Script), MT4/MT5 (MQL4/MQL5) - Automated Algorithmic Trading Systems – Python, API integration, crypto & forex - Backtesting, Optimisation & Robustness Testing – Walk-Forward Analysis, Monte Carlo simulations Unlike many developers, I also have a real trading background. This allows me to understand both the strategy logic and the technical implementation, which leads to more reliable trading systems. Currently studying computer programming, I spend my days coding and my free time improving trading systems — this field isn’t just work for me, it’s what I live and breathe. My approach is documented, performance-oriented, and pragmatic. Every project I take on is designed to be clean, efficient, and maintainable — built to deliver results, not just code. If you’re looking for a reliable, results-driven developer who truly understands both the technical and trading sides of your project, let’s discuss your strategy idea — I’ll help you turn it into a profitable, automated system. Typical projects I work on: • Automating manual trading strategies • Converting TradingView strategies into MT5 Expert Advisors • Building crypto trading bots using exchange APIs • Creating custom indicators and alert systems • Developing backtesting and research frameworks in Python What I can build for you: • TradingView indicators and strategies (Pine Script) • MT4 / MT5 Expert Advisors (MQL4 / MQL5) • Python trading bots for crypto and forex • API integrations (Binance, Bybit, Oanda, etc.) • Backtesting frameworks • Walk-forward optimization • Monte Carlo robustness testing • Strategy dashboards and performance reports

I'm an active trader and software engineer who builds quantitative trading systems from the ground up. I develop custom backtesting frameworks, screening tools, and automated trading pipelines in Python to support systematic strategies in US equities, with a focus on clean entry/exit logic, position sizing, and managing drawdown. As someone who actively trades using my own systems, I know the difference between a backtest that looks good on paper and one that holds up in live markets. I regularly work with trading APIs, data sources, and AI tools, including LLMs, MCP integrations, and multi-model setups, to streamline financial analysis and figure out what actually adds edge in a real trading workflow. My work covers the full development process: building reliable data pipelines, implementing and testing rule-based strategies against real performance metrics, and creating tools for every stage of trading, from market screening and signal generation to portfolio backtesting with proper risk metrics.
