1. Implementing accessibility api for MacOS VoiceOver2. Designing and constructing new accessibility feature with objective c and swift to help blind people3. Work together with QAs and PMs to improve VoiceOver's overall experience.

1. Extended HybridNet super-resolution model with Pytorch, benchmarked the gpu, memory and runtime bottleneck, and deployed the model on oculus quest 2. 2. Crafted temporal loss function/metrics with perceptual similarity and optical flow to reduce temporal artifacts.3. Understood OpenGL code and implemented ASW(Asynchronized Space Wrap) and ATW (Asynchronized Time Wrap) to align past images to current image with homographic matrix, motion vectors and depth information.

1. Collaborated with program manager, software engineer lead, and 3 software engineers to build the backend of a service that improves the success rate of test driving with Spring Boot and Flask. 2. Proposed and designed an algorithm for detecting the behavior of test drivers while driving; tested the algorithm in different cars and passed all test cases. 3. Optimized C# program that checked the performance of TCS and ACS system; reduced runtime by 80 %.

1. Optimized antifraud algorithms with various Machine Learning methods and got a KS score of .852. Collected, organized and cleaned 100,000+ customers data with Python and SQL for our team3. Compared different versions of bus information by Python to test the accuracy of Tencent’s newly launched mapping services
