Solid dev, really knows his stuff. Built a Polymarket trading bot for me with clean entry/exit logic, configurable tp/sl, and stable price feed integration. Delivered on time, caught and fixed bugs on his own without me having to point them out. Communication was smooth the whole way through. Would definitely hire again.
