About me
I build automated trading systems and the infrastructure around them: Binance / Bybit / OKX integrations (WebSocket + REST), WS-first order execution from ~4ms send latency, Go market-data gateways feeding Python (1500+ symbol streams across 3 exchanges, 30K msg/s peaks, zero-loss), and ML signal pipelines (XGBoost / LightGBM, regime models, walk-forward validation) over 100M+ rows in TimescaleDB. Runs 24/7 in production for months. Focus on the hard parts: latency, resilience (reconnect logic, circuit breakers, exchange-outage handling), and data integrity at high message rates. I take projects end-to-end — architecture, implementation, deploy. I run my own products (a trading system and a privacy/VPN SaaS with real paying users), so I understand the product/revenue side, not just the code. Paid in USDT or fiat.
