Seongjun Lee

Worked on jeejeelee/vllm, delivering two features over two months focused on backend and machine learning improvements using Python. Enhanced user-facing messaging by refining the IP fallback warning, addressing a subtle UI text issue to improve clarity when IP retrieval fails. Developed Gemma4 token-budget management for multimodal and video inputs, introducing configuration-driven logic to enforce maximum soft tokens and dynamic video token limits based on frame count. Added comprehensive unit tests to ensure reliability and regression safety. Demonstrated careful attention to detail, strong testing practices, and a scalable approach to both user experience and resource management in backend systems.
