About Jiahang Li
Data analyst with 5 years of data analysis and 3 years of the machine learning experience. Currently, I am a data scientist support ads ranking team to build privacy preserved ML model. I am interested in data scientist and software engineer positions that can improve my skills and learn new techniques.I acquire strong mathematical and programming skills during my Ph.D. study and develop an earthquake signal analysis package to help seismologist to image the earth structure. Familiar with multiple programming languages and tools such as python, C, flask, HTML, CSS, Github, etc.I am always motivated to learn and have self-studied machine learning methods. I also applied machine learning techniques such as PCA in my earthquake signal processing package. I see more potentials for machine learning techniques in the industry data set.As a team player, I like to propose ideas and brainstorm with others. I have presented in several international conferences and published research articles in top journals. They provide valuable experience to learn from others by exchanging ideas.
