General Education, Coding Education, Competitive Programming, Software Platform & Tooling.1. Leading complete curriculum from no foundation in programming => solid knowledge system buildup => top talents coaching. Leading different teams from different functions to assembly a high quality & scalable teaching solution.2. Granularity of thousand students grow in the curriculum with solid foundation built not just for competitive programming but for the future development in academia or industry.3. 12 USACO finalists in the past 3 years.4. First batches of students have achieved the following. 13 admitted to MIT (9 EA offers in Dec 2023), 1 of Caltech, 1 of Princeton, 1 of UC Berkeley, 1 of UT Austin, 1 of CMU.

1. From the ground-up, built a company with various departments that serves thousands of students & parents.2. Scalable teaching solution to serve both to-B and to-C clients.3. Technology platform to support, standardize & automate as much as possible. a. Content generation, presentation and management. b. Information management. c. Business intelligence analytics framework. d. Automation. e. Monitoring.4. Coaching system proved to be able to cultivate the top competitive programming athlete in the world.

Built large scale, high performance, [low latency realtime streaming / batch], [stateless / stateful] geo-replicated data processing system.● Working in Data Infrastructure & Analysis (DIA)● Worked in Ads Data Infrastructure & Ads Backend● Seasoned performance tuner, tricky-problem solver for complex system.● Determined leader / driver that unites resources and unblocks anything along the path to get things done.

● Improved Hotel search & matching algorithm with dynamic programming based on Markov model● Built the backend for monitoring of Hadoop Cluster

● The project focuses on the efficiency and accuracy of Image stitching, which is the process of taking thousands of high-resolution images of varying degrees of overlap and combining these images to construct panorama of a fossil site. Applied feature-detection algorithm(Speeded-Up Rubust Features) to retrieve the features of images. My work was funded by Howard Hughes Medical Institute (HHMI).

● Worked on vehicle routing problem by implementing modified genetic algorithms.
