Welcome
I am looking for full-time job opportunities as Software Engineer. I am proficient in C++, Java and C#. I have experiences in designing user interface with native code, handling network protocols down to data link layer, building full-stack applications into production, etc. My curriculum vitae is available on Linkedin.
About me
I obtained Ph.D in Computer Science from UC Riverside in Jun. 2024. My advisor is brilliant Dr. Eamonn Keogh. My research interest includes time series analysis, data mining, and machine learning. My Ph.D dissertation “Problems with Problems in Data Mining” is available on UC eScholarship.
I like travel, especially by rail and air. I’ve visited all 50 states (plus D.C. and Puerto Rico) in the U.S. and 11 countries around the world. I’ve spent 1,139.4 hours just in the air and travelled 687,032 kilometers by plane, that is 17.1x around Earth or 1.79x to the moon!
