Worked on the taoshidev/proprietary-trading-network repository, focusing on backend development and trading system reliability over a two-month period. Delivered a key feature that automatically closes positions when the order limit is reached, optimizing daily portfolio returns by reducing redundant API calls and improving processing efficiency. Addressed two critical bugs to enhance order validation and ledger accuracy, including safeguards for FLAT order processing and corrections to performance ledger calculations. Employed Python for backend logic, data analysis, and database management, emphasizing risk controls and system stability. The work reduced risk exposure, improved pricing integrity, and enabled smoother, more reliable automated trading operations.
