develop Diagnostic Software and Diagnostic OS solution, for Storage related devices (ATA/SATA/SAS/JBOD/NVMe/etc), Networking devices (Switch/OLT/ONT/etc), Servers (X86/SPARC/ARM/etc), Embedded devices, etc;develop kernel drivers and system applications for different platforms and products, BRCM Switch SDK/OLTSDK bring up and traffic test for Networking devices, SAS/FC/BIOS/VPD/FPGA/CPLD/JTAG programming tools, etc;BIOS/OpenBMC/U-boot development for Server and Networking products, ONIE/ONL/ONLP development for Networking products, etc.system integration, customization, building, CI/CD, automation, etc.lead projects, manage teams, development process, etc.good communication with customers, design and deliver to customers requirement for products (Sun/HP/IBM/NetApp/Juniper/Infinera/Radisys/Calix/etc.), communication with Open Source community, etc.

develop computer device diagnostic programs used for manufacturing line under Linux, including floppy disk test which test floppy device, cdrom disk test which test cdrom drive, ide disk test which test ATA disk, scsi disk test which test SCSI disk, serial port test which test SIO port, parallel port test which test PIO port, and usb test to test usb device, rtc test to test system RTC, audio test to test Sound card, cdrw test to test CD-RW/DVD-RW function, etc.bios flash chip drivers which supply kernel functions to update flash bios chip for Linux (both LPC interface and newer SPI interface with VIA, Intel ICHx, nVidia CK8, etc. chipsets written as char or mtd drivers) and FreeBSD; usb cable driver for Linux(as netdev device or raw char device, also user-level usb driver); patch ide core driver to fix reset bug in kernel mailing list (not accepted); hardware monitor driver for Linux (that based on i2c & lmsensors), and for SCO unix;lcd driver programs that gather system information and display on the lcd panel in front of server box for FreeBSD, hardware monitor program, fan speed monitor program that autotune cpu/system fan speed of server box, watchdog monitor program, system SN (mother board) update program that get/set system DMI data from/into bios, etc.power cycle test script for Solaris, diag control programs to schedule and run diagnostics under Linux, etc.build CD bootable diagnostic base system, rpm package making, etc.communicate with engineers from vendors (as Sun, HP, etc.) and from Open-Source community (like kernel mailing list and other subsystem mailing lists).
