Worked across three repositories to deliver targeted improvements in risk assessment, reliability, and UI clarity. In virattt/ai-hedge-fund, enhanced the Sortino ratio calculation by incorporating target downside deviation, increasing the accuracy of risk metrics using Python. Addressed a TypeError in browser-use/browser-use by removing an unnecessary await from a synchronous get_llm call, improving asynchronous flow in TypeScript. In Crosstalk-Solutions/project-nomad, refined the admin UI’s storage display logic to prioritize real block devices and added a fallback for unreadable mount tables, ensuring accurate capacity reporting. Demonstrated full stack development, bug fixing, and risk assessment skills with a focus on operational reliability.
