I've been writing trading bots since 2022, mostly for my own money, so I care a lot that things actually work. My main project is a platform that trades spreads on 40+ exchanges: Binance, Bybit, OKX, Gate, Hyperliquid, Lighter, ApeX, GRVT and a bunch of smaller ones. It runs 24/7, so I've already dealt with partial fills, rate limits, dropped websockets and exchanges changing their API without warning. I can help with: a bot for your strategy, arbitrage (cross-exchange, spot-perp, funding), connecting a CEX or DEX API to your code (EIP-712, zk signing), Telegram alerts and bots, scrapers. I'll ask a few questions first and tell you honestly how long it takes and what it costs. Mostly Python, but fine with JS/TS or Go. Short demo before delivery, free fixes for a week after.
