I need an experienced full-stack developer who is equally comfortable in C#, Python, REST APIs, and WebSockets. For our first milestone, I want to fix and test a minimal-viable connector for a decentralized exchange that can: • Stream real-time market data via WebSocket • Place, cancel, and query orders through the exchange’s REST API • Handle basic user authentication (API key / secret) Keep the code clean, well-commented, and organized so we can easily extend it to additional exchanges and advanced AI-driven analytics later. A simple command-line or lightweight web UI that demonstrates each core function is enough for this phase. I’m looking for someone interested in a long-term partnership. If this goes smoothly we’ll move on to scaling, multi-exchange support, and ML features.
