1993              Hewlett Packard‑ San Diego, CA

to 6/00           EMBEDDED SOFTWARE ENGINEER

At HP Research & Development, I developed Deskjet & Officejet product firmware.  My work organized around consumer product teams.  On teams I was fully responsible for various & specific components through the full product and software lifecycle from investigation & design through testing & maintenance.  On all projects I enjoyed honing my skills with Unix and embedded programming, including the design and product definition.  At HP I:

·         Designed, implemented and supported real-time control systems for temperature, current, motor velocity/position (steppers and other) using Matlab, C & assembly cross-compiled, embedded ISR’s for PID, LQG and other control systems.  This work was performed on several products, with various processors, assemblers, and cross compilers – including 68000, i960, coldfire and VxWorks.

·         Programmed c/assembly language ASIC interface and other performance/space critical embedded ISR’s, low level O/S interface and I/O code.

·         On all projects at HP I supported ASIC (digital hardware design engineers) designing custom IC’s through analysis, definition and test vector design.  Usually this required writing ASIC test code for design validation.

·         Authored & maintained C, C++ systems for color mapping & image processing ASIC simulators on Unix and for embedded targets.  Analyzed cost vs. image quality tradeoffs to save cost on ASIC and board design.

·         Performance analysis, board bring-up and debug with HP/Agilent in-circuit-emulators, debuggers (GDB, Tornado, logic analyzers, oscilloscopes and other test and measurement equipment.

·         Interfaced with manufacturing, marketing, management and research and other teams.  Identified and managed technical and schedule risks.

·         Development, interfacing and benchmarking of diverse wireless & wired network communications

·         Protocol Analysis reverse engineering

·         Full-lifecycle embedded system hardware and firmware solution development

·         Understanding and learning complex systems/technical designs and huge existing code-bases and leveraged existing designs. Through analysis of source code, or reverse engineering and/or scientific method where necessary

·         Performance critical (cache & bus-bandwidth, CPU bandwidth, memory, ISR latency, etc) critical analysis and design in resource constrained designs.

·         Analyzing/designing/programming low-level, real-time, multi-threaded, DMA, hardware-interfacing, interrupt (ISR) software

·         Embedded system electrical board bring-up and Emulators, logic analyzers, etc
