Most trading strategies fail in live markets because they are overfitted to the past. I solve this problem. I am a Quantitative Developer and Python Expert specializing in building automated trading systems that are statistically valid. I don't just write code; I provide the infrastructure to test, optimize, and execute your logic with precision. My Specialized Services: 🐍 Python Algorithmic Trading: - Advanced Optimization: Using Optuna to find the best parameter sets without curve-fitting. - Walk-Forward Analysis: Rigorous testing on out-of-sample data to ensure your strategy works in changing market conditions. - Data Mining: High-speed fetching of historical data (OHLCV) from exchanges (Binance, Bybit, etc.) via API to build reliable datasets. - Execution Bots: Connecting your logic to exchanges via CCXT or custom API wrappers for low-latency execution. 📈 TradingView & Pine Script: - Development of custom indicators and strategies (Pine Script v6). - Setting up webhook alerts for automated execution (connecting TradingView to Python/3Commas). - Converting manual strategies into strict algorithmic rules. ► ADVANCED METRICS & QUANT ANALYSIS (MY SPECIALTY) Standard metrics like ROI are not enough. I analyze the deep structure of your strategy using: 1. STATISTICAL SIGNIFICANCE - PSR (Probabilistic Sharpe Ratio) & Deflated Sharpe Ratio - P-Values & Statistical Significance of trades - Walk-Forward Matrix (WFM) Analysis 2. RISK & TAIL EVENTS - CVaR (Conditional Value at Risk) - Skewness & Kurtosis (Tail risk detection) - Exposure-Adjusted Returns 3. MARKET DYNAMICS - Market Regime Analysis (Trend vs. Range/Sideways performance) - Rolling Sharpe Ratio & Alpha/Beta calculation - Correlation matrices Why Me? You need to know if your strategy survives when the market changes. I provide the infrastructure and the math to answer that question. I focus on "Robustness" over "Raw Profit," ensuring your bot is ready for real capital. Click "Invite to Job" to discuss your strategy and let's run the numbers.

I'm a Top Rated quantitative developer on Upwork, currently completing my MS in Data Science at Harvard, with production experience building and shipping algorithmic trading systems across futures, options, and equities. My work spans the full pipeline: from signal research and rigorous backtesting through execution architecture and live broker deployment. Over the years I've collaborated with professional traders, systematic fund managers, and independent CTAs on strategy research, execution system builds, and quantitative infrastructure — working with live accounts and real capital, not toy portfolios. - Research Philosophy Most algorithmic trading research fails before it reaches live markets. The reasons are almost always the same: data snooping bias, fragile parameterization, fill simulation that doesn't reflect actual execution, and strategy logic never stress-tested against regime change. My research process is designed to make it hard to fool yourself. That means strict chronological train/test splits with no parameter bleedthrough, walk-forward optimization over anchored and rolling windows, block bootstrap for inference on autocorrelated returns, and parameter sweep frameworks built to expose fragility rather than maximize backtest metrics. A strategy that only works on one parameterization isn't a strategy, it's a coincidence. I care about robustness across parameter space, regime stability, and understanding exactly why a signal works before scaling it. I work extensively in QuantConnect's LEAN engine for research-grade backtesting and live account deployment, though deployment targets vary by strategy and client stack. IB TWS via ibapi, Tradovate, and NinjaTrader are all in regular rotation depending on execution requirements. I build custom analytics layers on top of backtest output: Sharpe decomposition, drawdown attribution, execution cost modeling, and signal decay analysis, because standard tearsheet metrics rarely tell the full story. - Strategy Coverage My research spans futures (NQ, ES), SPX and index options, ETFs, and crypto. Strategy types I've built and validated in production include intraday momentum and trend-following systems, mean reversion and stat-arb frameworks, breakout and scalp architectures with dynamic sizing tiers, options strategies including iron condors, defined-risk vertical spreads, 45-DTE and 0DTE SPX structures with delta-based hedge logic, and GEX (gamma exposure) driven directional frameworks using open-interest-weighted dealer positioning data. It's an area where the signal literature is still thin and where getting the methodology right matters more than most people acknowledge. - Execution Engineering The research-to-live gap is where most systems break. I build execution infrastructure that closes that gap: Interactive Brokers TWS via ibapi with state machine architectures, order ladder geometry, true breakeven calculations with commission and slippage factored in, and hedge math for multi-leg positions. On the NQ/ES side I've built and audited scalp bot execution logic on Tradovate, integrated Databento for professional tick data pipelines with proper validation against reference data, and developed Pine Script strategies and indicators on TradingView for signal prototyping before committing to full implementation. I'm also familiar with NinjaTrader's execution environment and ATM framework. Code I deliver is production-standard: structured logging, explicit edge-case handling, clean separation of signal and execution layers, and documented at a level where the system is maintainable after handoff. - What I Work On: - Strategy Research & Backtesting: QuantConnect/LEAN, Backtrader, Zipline, VectorBT, QuantLib, Python - Execution Systems: IB TWS/ibapi, Tradovate API, NinjaTrader, REST/WebSocket broker integrations, FIX Protocol - Retail Platform Development: MQL4/MQL5 (MetaTrader 4/5), Pine Script (TradingView), NinjaScript (NinjaTrader 8), EasyLanguage (TradeStation), ThinkScript (Thinkorswim), cAlgo/C# (cTrader), AFL (AmiBroker) - Broker APIs: Interactive Brokers, Alpaca, TD Ameritrade, Tradovate, Oanda, Databento - Crypto Platforms & APIs: Binance, Bybit, OKX, Kraken, Coinbase Advanced Trade, Bitfinex, Deribit (options/derivatives), KuCoin, Gate io, Freqtrade, Hummingbot, 3Commas, Pionex, Gunbot, ccxt (unified exchange library) - Statistical Testing: Walk-forward testing, parameter sweep analysis, Monte Carlo simulation, bootstrap inference - Full-Stack Delivery: Data ingestion → signal research → backtesting → live deployment

Senior Algo Trading Developer | cTrader (c#), TradingView & NinjaTrader You need a developer who understands market structure, not just syntax. As a software engineer and active trader with nearly 10 years of experience, I build professional trading systems that do exactly what you expect them to do—reliably and precisely. I have completed 100+ trading projects, delivering maintainable, clean code rather than "quick hacks." My core expertise includes: cTrader / cAlgo (C#) Custom cBots, indicators, and trade management systems. Licensing systems and dashboards. Note: I am an active contributor to the cTrader Developer Network (CTDN), ensuring strict adherence to platform architecture. TradingView (Pine Script v4/v5) Strategy and indicator development. Multi-timeframe logic, scanners, and alerts. Converting ideas into non-repainting scripts. NinjaTrader 8 (NinjaScript) Advanced automated strategies and execution logic. Custom UI tools for discretionary or systematic trading. Why work with me? I don’t just "code what you say." I challenge unclear logic and help you refine your edge to ensure the final system behaves correctly under real market conditions. I understand risk management, execution rules, and edge preservation. If you value precision, honesty, and experience, let’s discuss your strategy.

You have a trading strategy. Maybe it's live, maybe it's just a backtest, maybe it's a TradingView script you don't fully trust yet. The hard part was never the idea, it's making it run reliably when real money is on the line. That's what I do. I take trading strategies from concept → backtest → production execution, and I build the infrastructure that keeps them running. I don't sell alpha, signals, or "guaranteed returns." I'm the engineer who makes sure your system actually executes, accurately, every time, under live market conditions. What I build - Backtesting & research platforms with realistic fills, slippage, and fees, so your results survive contact with live markets - Live execution engines, async, fault-tolerant, built to recover instead of crash - Exchange & broker integrations over REST, WebSocket, and FIX - Real-time market data pipelines and order management systems - Monitoring, dashboards, and the production infrastructure that keeps it all alive Recent work - Built a NautilusTrader-based backtesting platform with a live performance dashboard - Audited and validated a multi-market algo system across NQ futures, forex, and commodities I hold a 100% Job Success Score with consistent 5-star reviews, and most projects turn into long-term work. Platforms & connectivity - Custom Python systems, NautilusTrader, QuantConnect/Lean, MetaTrader 5 (MQL5), NinjaTrader, and TradingView/PineScript, including converting TradingView scripts into real Python execution systems. - Exchanges: Binance, Bybit, OKX, Coinbase, Bitget. Brokers: Interactive Brokers, Zerodha, Dhan, Upstox. - Prediction markets: Polymarket, Kalshi. Whatever your edge, market making, arbitrage (CEX/DEX/cross-exchange), mean reversion, stat arb, options, or ML-driven, I've built and validated it in production. I implement and harden strategies; I don't claim to invent them. Background Before freelancing, I spent 8+ years building trading systems professionally, including a live market-making system trading BTC and ETH across Binance and OKX with ~12ms execution and Deribit options hedging, plus cross-exchange smart order routing for institutional OTC flow. I bring that same production rigor to every project here, whether it's your first bot or a fund's execution stack. If you want to automate a strategy, fix a backtest you don't trust, connect to an exchange or broker, or take an existing system into production, that's exactly what I do. Tell me what you're building.
