Python Trading Infrastructure Engineer | Exchange Connectivity | Backtesting | Live Execution | GMT+7 I build the infrastructure that makes trading strategies actually work in production: exchange connectors, real-time data pipelines, backtesting engines, and live execution systems. My background is in trading systems engineering, not strategy development. I don't generate alpha, I validate it and build the systems that execute it reliably, fast, and correctly. If you have a strategy that needs to be automated, backtested properly, or connected to a live exchange, that's what I do. ▶ TECHNICAL EXPERTISE ◀ • Exchange connectivity: Binance, ByBit, Coinbase, OKX, Bitget, Interactive Brokers (IBKR TWS) • Trading frameworks: Hummingbot (top-10 OSS contributor) | NautilusTrader | QuantConnect • CEX and DEX connectivity | WebSocket market data | REST order management • Backtesting engines: correctness, performance optimization, realistic fill simulation • Prediction markets: Kalshi, Polymarket • Languages: Python, Cython, C++ • Low-latency optimization: asyncio profiling, network tuning, thread isolation • Strategy types supported: arbitrage, market-making, trend-following, mean-reversion, grid bots • Data: NumPy, Pandas, Dask, Parquet, PostgreSQL ▶️ WHY CHOOSE ME ◀️ 8+ years building trading systems professionally, including 2 years at CoinAlpha (Hummingbot, top-10 OSS contributor), ongoing freelance work across crypto, equities, and prediction markets.

**Quant Trading Engineer | Backtesting, Automation, Research, Hedging** I build institutional-grade backtests, strategy validation and trade tooling across US equities, options, derivatives and crypto. Expect clean assumptions, reproducible runs, and clear diagnostics (PnL decomposition, robustness checks, and failure modes) that I will be able to translate trade automation. What I do: • Backtesting & Strategy Validation: Rules-based strategies, scenario testing, overfit conscious optimization, and robustness/OOS checks. I focus on bias-aware implementation and interpretable results. • Hedging & Risk Overlays: Delta hedges, band/regime-based hedging policies, funding/carry modeling, and PnL decomposition (what comes from fees vs hedge vs carry vs costs). • Trading Data Pipelines: ETL workflows, time-series cleaning, automated storage, and reproducible datasets. Integrations with data sources and formats your workflow requires. • Automation & API Work: Automating analysis, integrating necessary APIs, building scheduled jobs, and removing repetitive manual work. Supporting broader automation tasks to reduce manual work.
