# Javin Liu > Software Developer Engineer Location: Campbell, California, United States Profile: https://flows.cv/javinliu I’m a Software Development Engineer in the Healthtech industry, passionate about building impactful, data-driven products. I hold a Master’s in Computer Science from the University of Southern California and a Bachelor’s in Computer Science and Statistics from McGill University. My focus areas are Machine Learning and Natural Language Processing (NLP) — and I’m especially interested in applying these technologies to fields I’m passionate about: music, fitness, human behavior, and emerging tech. I love collaborative teamwork, continuous learning, and exploring how technology can improve lives. Outside of work, I’m a bit of a tech enthusiast with a growing interest in Health tech and how innovation shapes our future.

Reihaneh Rabbany Intern research assistant for the complex data lab. -Engineered prompts for gpt3.5 that was used to generate a human trafficking NER dataset (HTGen) -Exploited LLMs to generated synthetic annotations for a cost effective way to get labels on niche domains as well as domains where the data is highly sensitive and thus not perfered to be labeled by human annotators. - Explored rule base gazetteers and knowledge bases of human names. - Continual learning to expand existing knowledge bases - Surveyed the ethics (bias and toxic lanugage) in GPT generated synthetic human trafficking domain data.

The club's mission is to bring FinTech literacy to the broader campus. We intend to achieve this through lectures/workshops hosted by professionals, and events to get students interested in FinTech together. We intend for our main topics of interest within FinTech to be varied. Currently, we have one event planned. Professor 谢国斌 will be coming in to talk about hot topics in the realm of computer science and finance. He is currently the vice president of China Information Engineering Institute, and the General Manager of AI R&D Center and Chief AI Scientist. He also has a enormous amount of knowledge and experience in the Finance Technolgy industry. He has previously worked in China Mobile, Huawei, Baidu, and other large fortune 500 Chinese companies. We are hoping to host more lectures and are hoping to help students better understand finance and technology!

The information was hosted on a google cloud server. •Published to a conference and indexed by SPIE Digial Library. •Find it here : https://doi.org/10.1117/12.2623112 ### Research and Learning Person @ Massachusetts Institute of Technology Jan 2021 – Jan 2021 | Massachusetts Ave, Cambridge Took a Machine Learning Bootcamp similar to McGill University's Mais 202 with professor Mark Vogelsberger from MIT along with Path Academics. I learned about machine learning frameworks including Tensorflow, Pytorch, and Keras. I learned about important Machine Learning Models including Gan, RNN, and Neural Network. Learning about writing research papers and fundamental academic paper writing. ### Artificial Intelligence Research Lab @ McGill University Jan 2021 – Jan 2021 | Montreal, Quebec, Canada Under the supervision of Prof. Joseph Vybihal, I researched neural networks and implemented code that used multi-threaded matrix multiplication to improve the performance speeds of the neural network code. I decreased the algorithm execution time by half and implemented code to make the NN be able to read from disk in batches and train in batches to help the model be able to scale to larger datasets that would otherwise cause the code to crash due to the heap running out of memory. ## Education ### Master of Science - MS in Computer Science University of Southern California ### Morgan Stanley Investment Banking 101 Financial Edge Training ### Bachelor's degree in Computer science and Statistics McGill University ## Contact & Social - LinkedIn: https://linkedin.com/in/javinliu - Website: https://github.com/javinator48 - Website: https://www.javinliu.com/ --- Source: https://flows.cv/javinliu JSON Resume: https://flows.cv/javinliu/resume.json Last updated: 2026-04-05
