Belle’s strengths include designing system architectures for intelligent functions that can reason and make decisions rather than simply react to inputs. Belle has built an AI model that analyzes bill images, including numbers and QR codes, and routes requests to video or text APIs according to contextual needs. Belle has also independently iterated and expanded AI features while tackling complex AI architecture challenges. At USC Viterbi, Belle participated in LLM research focused on fine-tuning the LoRA component of large language models and contributed to an ACL paper publication. Earlier research at China University of Geosciences \(Beijing\), conducted through a CUGB–MIT-connected collaboration led by an MIT researcher, focused on deep-learning medical image segmentation and resulted in a published paper. Belle has experience as a Software Development Engineer Intern at AWS, a Technical Support Engineer at State Grid Corporation of China, and an on-site technical support assistant for the Beijing 2022 Winter Olympics. Belle is seeking to devote more time to AI product work and is open to hybrid, remote, and fully on-site arrangements. ## Services - C++ Python Java JavaScript Springboot TensorFlow pytorch - Machine Learning ## Highlights - Built an AI model that analyzes bill images, including numbers and QR codes, and routes requests to video or text APIs based on contextual needs. - Designed architecture for intelligent functions that can reason and make decisions rather than only react to inputs. - Independently iterated and expanded AI features while addressing complex AI architecture challenges. - Completed a Software Development Engineer Internship at Amazon Web Services \(AWS\). - Participated in USC Viterbi School of Engineering LLM research focused on fine-tuning the LoRA component of large language models. - Took part in an ACL paper publication through LLM research at USC Viterbi School of Engineering. - Conducted deep-learning research on medical image segmentation as a member of the Artificial Intelligence Research group at China University of Geosciences \(Beijing\). - Contributed to a CUGB–MIT-connected research collaboration led by an MIT researcher. - Published one paper from medical image segmentation research. - Provided on-site technical support for the Olympics Family Hotel during the Beijing 2022 Winter Olympics, including webpage maintenance. - Worked as a Technical Support Engineer at State Grid Corporation of China. - Earned a Master’s degree in Electrical Engineering from USC Viterbi School of Engineering, listed in 2024. - Skilled in C++, Python, Java, JavaScript, Spring Boot, TensorFlow, PyTorch, and machine learning. ## Experience - **Software Development Engineer Internship at Amazon Web Services \(AWS\)** (2024-06-01–2024-09-01) - **LLM Research Participants at USC Viterbi School of Engineering** (2024-01-01–2024-09-01) — Research is about finetuning Lora part for LLM, take part in one ACL paper publishment. - **Beijing 2022 Winter Olympic On-site technical support assistant at International Olympic Committee – IOC** (2022-01-01–2022-03-01) — On-site technical support for Olympics Family Hotel.
