CCXT is a single TypeScript codebase transpiled to JavaScript, Python, PHP, C#, Go, Java and Rust — every change has to work identically in seven languages. My contributions include:

• 🏗️ New exchange integrations built from scratch: Deepcoin, HashKey, Coincatch, OX.FUN, Polymarket Perps
• ⚡ WebSocket (ccxt.pro) implementations: real-time orderbooks, trades, balances and orders for TradeOgre, LBank, XT, WhiteBIT and more
• 🎲 Prediction-market integrations: Opinion, sx.bet (WebSocket via Centrifugo)
• 🔍 Deep exchange audits — endpoint-by-endpoint verification against live APIs with static-fixture regression tests: WhiteBIT, XT, WOO / WOOFi Pro, WEEX, Toobit, Poloniex, Kraken Futures, Alpaca, Upbit, Tokocrypto, P2B, Phemex, Paradex, Pacifica, Bitget, ModeTrade, Lighter, Nado, Mudrex, LAToken, MEXC
• 🧩 New unified methods — e.g. a full history suite for Kraken Futures: fetchTradingFees, fetchLedger, fetchFundingHistory, fetchPositionsHistory; liquidations for Hyperliquid: fetchMyLiquidations, watchMyLiquidations
• 📈 Advanced trading features: trailing stops, trigger & TP/SL orders, margin/position management, sandbox & demo-trading modes
• 🛠️ Unified API maintenance across dozens of exchanges: Binance, OKX, KuCoin, Kraken, Bitstamp, BitMart, HTX…
• 🍳 ccxt-recipes — the same five trading tasks solved in all seven CCXT languages, side by side
