Architected and developed a high-performance Python-based algorithmic framework featuring custom real-time market data gateways, sophisticated data screeners, and scalable multi-asset logic modules. Flexible Distributed Architecture: Supported lightweight local execution for focused data monitoring, and robust server-side deployment for massive multi-asset data processing. Seamless Terminal Connectivity: Built a highly customizable local GUI to visualize real-time screening reports and strategy triggers, ensuring seamless API integration with industry-standard platforms such as MetaTrader and IBKR. Robust System Integrity: Implemented critical fail-safes (Pause/Resume/Terminate controls) within the GUI for active logic modules to ensure stability and prevent unintended automated order processing during extreme market volatility. High-Performance Computing: Leveraged the asyncio framework for asynchronous I/O and pandas/polars for vectorized data processing, ensuring ultra-low latency and high-throughput performance.
