Anyone can scrape a page. The hard part — and what I do — is turning messy market data into something you can actually trade on: clean pipelines, point-in-time-correct databases, and bots that survive running 24/7. I build trading-adjacent data systems end to end: - Market data & pipelines — login-gated and JS-heavy sources, multi-source collection with failure isolation, normalized into Postgres/DuckDB - Point-in-time correctness — bitemporal databases with as-of replay and zero look-ahead leakage, so your backtests aren't lying to you - Signals & automation — rules-based market scanners, exchange API integration, Lightning/crypto automation, crash-resilient 24/7 deployment Recent work (real, with code & tests): - A bitemporal horse-racing trading database — Betfair historical pricing (600K+ price rows) + 280K+ race-card index, as-of replay validated leak-free, 176 passing tests (PostgreSQL/SQLAlchemy) - A Bitcoin (RoboSats) selling-automation system — 18-state order lifecycle, Lightning payments via Core Lightning, Tor routing, Docker API - A prediction-market arbitrage radar — scans 5,000+ live markets per cycle for YES/NO mispricing, DuckDB snapshots, 17 passing tests I care about correctness — bad data quietly ruins a trading system, so I build in reconciliation, idempotency and tests. Clear communication in English and Chinese. I'll tell you upfront if an edge isn't realistic rather than overpromising.
