Senior full-stack developer from Moldova 🇲🇩 — core contributor at CCXT, the cryptocurrency exchange trading library used by thousands of trading bots and fintech products.

🏆 85+ merged PRs · top-25 of 350+ contributors at ccxt/ccxt · contributing since 2024

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

• 🏗️ New exchange integrations built from scratch: Deepcoin, HashKey, Coincatch, OX.FUN
• ⚡ 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, in review)
• 🔍 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
• 📈 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 six CCXT languages, side by side
