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

I'm a Senior Quant trader and researcher designing institutional-grade, execution-ready trading systems for hedge funds, proprietary trading desks, and advanced fintech teams across both Forex and crypto markets. I specialize in turning robust alpha hypotheses into live, low-latency trading engines with proper risk, monitoring, and fail-safes built in from day one. My core edge sits at the intersection of market microstructure, statistical arbitrage, execution algorithms, and production software engineering. From high-frequency execution to liquidity-providing market-making, I build systems that are latency-aware, resilient under stress, and designed for real capital, not just attractive backtests. What I build High-performance execution and HFT-style engines: microstructure-aware execution logic, latency optimization, queue positioning, and adaptive execution tactics across multiple venues. Statistical arbitrage and market-making strategies: spread modeling, co-integration, pairs and baskets, inventory and quote-risk controls, and continuous PnL/risk monitoring. Trading aggregators and smart order routing: multi-exchange connectivity, routing logic, internal crossing, venue selection, slippage control, and real-time risk/hard-limits. ML- and LLM-augmented research pipelines: feature engineering for non-stationary series, signal stability testing, reinforcement-learning style policy evaluation, and sentiment/NLP inputs where they add real edge. Crypto and DeFi execution: CEX/DEX arbitrage, AMM routing, perpetual swaps, and integrations across on-chain protocols and off-chain venues. Platforms and stack Trading platforms (TradFi): MetaTrader 4/5 (MQL4/MQL5), NinjaTrader, Sierra Chart, TradingView (Pine Script), QuantConnect, Interactive Brokers, ThinkOrSwim. Crypto venues: Binance, Bybit, BitMEX, OKX, Deribit, dYdX, and major DEXs such as Uniswap, Sushiswap, and GMX. Low-latency & backend: C++, C#, Rust, Python, with practical experience building production trading and automation tools and server-side components. Infrastructure: Kafka, Redis, TimescaleDB/PostgreSQL, Liquibase, Docker, Kubernetes, and event-driven data pipelines suitable for live trading and research. AI & ML: TensorFlow, PyTorch, Scikit-learn, Pandas, and LLM APIs to augment alpha research, monitoring, and execution decision layers. How I approach ML in trading Financial markets are non-stationary, regime-driven, and adversarial, which means most naive ML pipelines decay quickly or overfit to noise. My process is hypothesis-first: alpha and market intuition come before models, with ML used to refine, stress-test, and scale strong ideas rather than search blindly for patterns. I rely on robust validation frameworks: walk-forward analysis, stability and sensitivity testing, Monte Carlo and resampling approaches, and realistic execution modeling including slippage and microstructure effects. The end goal is always the same: execution-ready systems that can be deployed, monitored, and iterated in production, not just impressive backtest charts. Partnership and engagement I work best with hedge funds, prop desks, and fintech teams that value deep market understanding, clear risk frameworks, and engineering discipline as much as raw performance. Beyond delivering code, I help teams refine their alpha pipeline, improve execution quality, and design architectures that can evolve as markets change. If you are planning to build or upgrade an institutional-grade trading stack whether it is a stat-arb engine, options or derivatives infrastructure, multi-venue execution layer, or ML-driven research platform share a brief description of your current setup, venues, and constraints, and we can map out a concrete plan
