Embedded software/firmware architecture, secure bootloaders, system bringup, network security, Internet of Things (IoT) security, anticloning, ASIC verification, code optimization.

Languages: C/C++, Objective C, Assemblers of ARM, PowerPC, x86, 8051, PIC, AVR, PDP-11.

Networking protocols: Ethernet, WiFi, OC-3/SONET, Frame Relay, TCP/IP, SNMP/MIBs, GEM/SECS, etc.

Operating systems: uCOS, OS-X, Linux, Solaris, VxWorks, Windows.

Firmware:

• Board Support Packages (BSP) and boot loaders; secured bootloaders and images
• Firmware for ASIC (SOC), system hardware simulation and verification.
• Direct-to-the-metal firmware, proprietary kernels, interrupt handlers for 4/8/16/32-bit microprocessors and microcontrollers.

• Hardware anticloning protection. Prevent pirating of the hardware and the software/firmware.
• HSM-based Certificate Authority and Public Key Infrastructure.
  User data security.

My experience ranges from turnkey design and development to supplemental engineering support.
