@kend27

Hi, I’m a senior Python engineer with hands-on experience building real-time, low-latency systems, including trading and execution infrastructure. I’ve designed modular execution frameworks using WebSockets and REST, implemented order lifecycle management (market/limit/cancel, partial fills), and built fault-tolerant market data pipelines with reconnect logic and state recovery. I’m comfortable separating exchange-specific adapters from shared execution logic, and I pay close attention to correctness, one-time triggers, and performance—especially in latency-sensitive environments. I also enjoy refactoring existing codebases to improve structure, clarity, and maintainability without sacrificing speed. I’m happy to complete the paid technical assessment and deliver clean, well-documented code with simple demos that clearly show execution flows across multiple exchanges. Best regards, Ken

@juanestebana17

Hi there, I bring 8+ years of Python engineering focused on scalable, low-latency systems and real-time data processing for trading infrastructures. I will design and implement a modular, plug-and-play Python execution framework with WebSocket and REST adapters for multiple exchanges (Hyperliquid, OKX), featuring robust order execution logic (market, limit, cancel, partial fills) and advanced capabilities like chase orders, trailing stops, and stop loss / take profit. Real-time market data handling with automatic reconnect and fault tolerance, plus safe one-time trigger semantics for durable positions. I will refactor existing code to improve clarity and performance, aligning with HFT-like requirements and delivering clean, maintainable demo scripts that illustrate the flow. The architecture will separate exchange-specific adapters from shared execution logic, enabling easy addition of new venues and matching the provided attachment expected_Architecture_very_simple.png. What are your top latency targets and the initial set of exchanges you want supported in the first milestone (e.g., Hyperliquid and OKX), and do you have any preferred CI/CD workflow or testing framework for the assessment? Best regards,
