* Leads a team in the development of an Automatic Vulnerability Detection System, resulting in the successful release of 6 firmware versions on planned dates through the application of agile software development framework (SCRUM). The backlog completion rate exceeded 80%.* Developed a fuzz testing framework that supports over 60 network communication protocols including TCP/IP, HTTP, TLS/SSH, streamming protocols, and various SCADA/ICS protocols.* Successfully hacked more than 6 devices including Smart TVs, Networking DVDs, CANBUS PLCs, Cleaning Robots, and BMS of Electric Vehicles. Provided detailed reports highlighting security issues related to hardware and software.* Instructed on hardware hacking and fuzz testing methodologies to peers.

* Established a collaborative working environment for source code management using SVN server. A series of semi-automatic scripts were used to construct firmware with cross-compilers and toolchains.* Led the development of a 4/8 channel DVR product based on the GM8187 solution. Conducted research on video and audio encoding techniques such as H.264, MPEG4, and ADPCM.* Developed an IPCAM product based on the GM8180 solution. The video and audio streams were transmitted to CMS through a proprietary protocol.* Conducted research on the ONVIF standard.* Implemented a value-added feature in the DVR system to control Access Control Devices, Smoke Detectors, and Motion Sensors through the RS485 network.

* Joined a project to develop an IP-camera product based on an embedded MIPS SOC and the Linux-mips operating system.* Enhanced the firmware of an 8-channel video server project, which included applications and a portion of drivers.* Implemented an I2C driver using GPIO interface to control IR-CUT and IRIS modules.

* Managed UNIX systems, specifically SunOS and Solaris, which involved tasks such as setting up automatic tasks using the cron table and shell scripts, managing user accounts, and allocating system space.* Conducted research on signal and digital image processing techniques, including FFT, DCT, WT, and edge detection, to transfer data between the time domain and frequency domain.* Analyzed a communication system that transmitted data through the link and developed software to extract data.* Developed a signal processing software that recorded analog signals by controlling a Sound Card and MOXA C502. The software also performed digital signal processing functions, such as FFT and Hamming filter, to draw a spectrum on the screen, also catch the signal by detect the preamble.* Designed a hybrid structure of AVL trees and linked lists to quickly sort and compare a huge quantity of files, up to half a million.
