Sr. Software Engineer
Information Technology
Sep 2007 - Jan 2009
  • Improved firmware for IPMC achieving the goal of high availability computing, through coordination of power-on privileges and backplane bus usage, hotswap management, damage prevention, resetting and re-loading frozen devices, remote power-on control, and remote sensing
  • Developed device drivers in the Linux environment for the shelf management blade; the drivers coordinated access among multiple authorized threads, modeled the system of the box, and provided a protocol interface to the system
  • Analyzed and resolved mismatches between existing systems and specs, for embedded real-time threaded IPMC code; analyzed possible coordination issues between devices across buses

Information Technology
Nov 2006 - May 2007
  • Designed circuits for digital audio products, including D/A converter, current-controlling precision volume control, class-D amplifier, power distribution, power level-shifting and regulation; in order that these cores were power-efficient, size-efficient, low-noise, and able to source enough current when needed for a quality audio system
  • Provided layouts with efficient use of area, low parasitics, low power losses and according to specification with simulated circuits
