We provide high quality development for fintech. You don't need to explain to us what is "order book", connector, "front run" and other trading words. We are new to UpWork, but not new to fintech development. We work with crypto API's, DEX, US stock market (Interactive Brokers, ALPACA, ThinkOrSwim). HFT is also one of our main specializations. We worked with Pump Bots, Arbitrage Bots, FrontRun bots for DEX and others.
