bringups.Developed tools and diagnostics to help new platform bringup as

well as deployed system management and post-mortem.

Staff Engineer, Linux Sofware Engineering,

Menlo Park, CA (Dec. 2000-May 2004)Technical lead for Sun project to enhance autofs on Linux

(dubbed AutofsNG).Author and maintainer of the Linux ACPI daemon (acpid), which

is shipped in most Linux distributions.Consulted with groups across Sun on Linux kernel and low-level

issues, including writing drivers and porting apps.Maintainer of Linux's driver for National Semiconductor dp8381x

ethernet controller.In charge of cleaning and pushing Linux kernel patches back to

the community.Maintainer of Linux kernel for Sun Linux and Cobalt

products.Worked with key customers on Linux kernel and low-level

issues.Developed tools/methods for enhanced use of SunRay clients with

smart cards.Developed SunRay/Linux loopback audio driver.Helped establish the first BitKeeper installation at Sun.Lead architect for Cobalt's CCE product (part of the Sausalito

architecture).Developed internal software development processes.Wrote several specifications for portions of the Cobalt software

stack.

Systems Software Engineer,

Mountain View, CA (May 1999-Dec. 2000)Ported Cobalt Linux kernel work to Linux 2.4.Co-architected and implemented Cobalt's backend architecture

"Sausalito" (responsible for the Cobalt Configuration Engine).

The Sausalito architecture was eventually open-sourced, and is the

basis for several projects.Modified, debugged, and enhanced Linux kernel for various needs:

network drivers, TCP stack, various device drivers, PCI

subsystem.Implemented Sausalito Internationalization (i18n) library.Wrote Sausalito-based Active Monitor application and UI.Wrote large portions of the Sausalito Developers Guide (SDK).Co-developed and maintained firmware (BIOS) for RaQ3, RaQ4,

Qube3, RaQ XTR, and RaQ550 products (x86).Developed tools to help developers flash BIOS and use newer

kernels on Cobalt x86 hardwareDeveloped PCI BIOS subsystem for x86 firmware.Debugged and helped diagnose board-level problems.Responsible for partial schematic reviews for new boards.Maintained CVS servers for internal and external access.Maintained and debugged Mips/x86 kernels and libraries.Cobalt acquired by Sun Microsystems.

Programming Coordinator / Lead Programmer - Residential Computing, Normal, IL (Aug. 1996-May 1999) Supervised, consulted with, and trained other programmers.Maintained Linux based web and multi-purpose servers.

Designed and implemented ISU Summer Conference Management System.

Written in Visual FoxPro (Oct. 1996 - May 1999).Created the application framework and standards definitions used

by the programming staff at the ISU Office of Residential Life on

all software projects. (Jan. 1997 - May 1999).Redesigned and authored the ISU campus-wide computer lab printing

solution (Sep. 1998 - May 1999).

Programming

Experience Active Languages:

ANSI C and C++, POSIX, UNIX Shell, Awk, x86 Assembly

Lex, Yacc.

Stale Languages:

Perl, PHP, Java, Visual FoxPro, SQL, Visual Basic, some TCL/TK,

Python.

Operating Systems:

Linux (since 1994), IRIX (3 years), Solaris, most UNIXes,

Windows 3.x/9x/NT/XP, DOS, some MacOS and MacOS X,

Novell Netware 3.x/4.x.

Project Contributions:

Linux kernel, GMPI, Cistron RADIUSD, Samba, shadow suite, RPM,

GLibc, PThreads, GLib, GNOME, PPPd, FreeS/WAN, ethtool, acpid,

SWIG, flam3, prettyprint, and more.

Frequent contributor to the Linux kernel in various areas.Wrote the implementation of the PSet specification for the Linux

kernel. Resurrected PSet as the generic procstate interface for

Linux.Started and lead the prettyprint project, which is a generalized

system for reading/writing hardware devices in a human friendly

way.Made flam3 (fractal flame renderer) run efficiently on N

processors. Changes mostly involved removing contended locks and

using atomic operations instead. Final result is near linear

speedup for N processors.

De-facto leader of the Generalized Music Plugin Interface (GMPI)

working group (an MMA sanctioned group designing an open-standard

audio plugin API), now defunct. Many of our ideas were incorporated

into Steinberg's VST3 standard.

Released free classes, libraries, and code samples for Visual

FoxPro (1998-1999).Chief developer and project leader for a Java implemented

Assembler and Virtual Machine simulator for the ACS curriculum

(Feb. 1997 - May 1999).Helped in the initial conversion of the shadow suite for use

on Red Hat Linux 4.2.Designed and implemented a custom toy OS from scratch.
