Hushan worked on feature development for Company-B-MSD/tripmate and Jaseci-Labs/jaseci, focusing on user experience, authentication, and AI workflow safety. For tripmate, Hushan simplified the Destinations UI by removing redundant navigation and aligning navigation logic with authentication state, using React and Spring Security. He also enhanced the OAuth2 user model to support JWT-based authentication by extending user objects with database information and accessors. In Jaseci, Hushan implemented a configurable iteration limit for ReAct tool-calling loops in LLM invocations, using Python, to prevent infinite execution and ensure reliable AI-assisted reasoning. The work demonstrated thoughtful engineering and robust problem-solving.
