Algorithm Engineer: Develop object detection & tracking algorithm for MOT (Multiple Object Tracking) to improve public safety, like to help police officers to locate and track suspects and lost children by surveillance video stream analysis. Pattern recognition with deep learning network, helps SCTV editor to record interested video stream, label them with subtitles generated by OCR.AchievementsDeveloped high performance pedestrian tracking system, in beta test in 2 police departments. A video stream record system, deployed in province TV station.Platform / Software / Tools Python, Linux, pyTorch, Caffe/Caffe2, Visual Studio Code, Git

Senior Engineer and Project Leader: Develop new features for MOTOTRBO two-way radios base station, like Charging for Software, Dynamic Mixed Mode, Linked Connect Plus; Hardware and software migration for the Next Generation Repeater, providing driver for new hardware module;Cooperate with world-wide teams in USA, Malaysia and Poland, lead team in the whole product life cycle: analyze requirements, implement features, monitor the dependencies and risks, prevent potential issues with code reviews / test automation / failure mode and root cause analysis, improve process with ROI analysis, resolve critical issues found in released products and provide new software upgrade ASAP.Scrum Master: Adopt Agile methodology in daily work for more than one teams, like planning game, daily stand-up, retrospective and review meeting; Recruit and mentor the new employees; Team building.ARM Cortex A8 / Nucleus / TI CSS, TCP/IP, DHCP, Git, JIRA, Bitbucket, Rational Rose RT, Clearcase, Source InsideOther InitiativesA. Agile Dashboard for Continues IntegrationMonitor screen to demonstrate Continuous Integration status, the build progress and data analysis like CI progress, test cases and coverage, active submitters; HTML5, CSS3 and JS (Ajax, RactJS, Bootstrap), JenkinsB. Smart Display for Infrastructure DevicesUse smart device as remote display of the repeater via WIFI, for diagnostic information, control, voice recording and playback. The first version is a cross platform app, written in C++ with Cocos2d-x. The second version is written in Java Script and HTML5/CSS3. Android, iOS, C++, Cocos2d-x, HTML5 (Web Socket), CSS3 and JS, HBuilderC. Analyzer for ECloud Builder A web based graphic analyzer to improve the concurrent build efficiency on ECloud servers. Engineer can clearly analyze the clustered server profiling, find the root cause which causes the long building time. It reduces the firmware build from about 20 minutes to 3 minutes.HTML5, Canvas, CSS3 and JS
