Skills:

C/C++:

Most of what I did at Isilon was in C++, and my work at Zillow was
about 50% C++, and at Amazon and The TC I worked primarily in C++; I
used C and C++ extensively all through school and at both of my
Microsoft internships.  This was my first major programming language,
self-taught before I started at Cornell, so I probably have close to 9
years of C/C++ experience now.

Java:

I worked with Java at Zillow using the Tapestry web application
framework to develop features and fix bugs in their search pages.

Networking:

I have experience with TCP/IP networking and client/server
architecture.  One of my main projects at Zillow was a multithreaded
'change broker' server written in C++ for a UNIX environment,
responding to queries from its on-disk data store and in-memory cache
via HTTP.

UNIX/Linux:

I have extensive UNIX/Linux experience; every position I've held since
I graduated involved substantial programming on a Linux platform, so
that makes about four years of professional experience, and I've used
Linux on Intel or SPARC platforms and SGIs at home exclusively since
the 1990s.

Other programming languages:

I have significant professional experience with Java (at Zillow) and
Perl (at Amazon).  I also have experience with assembler for x86, MIPS
and SPARC processors.

Experience:

Envision: Software Development Engineer, February 2009 to July 2009

 * Worked on integrations with vendor-specific APIs for telephony server
   product, mainly in C++ and C#.  Implemented RTP transmitter to play
   sound files back to VoIP, including decoders for MS-GSM and VOX ADPCM
   formats.

Isilon Systems: Software Development Engineer (Contract), November
2008 to January 2009

 * Worked on startup scripts and developed runlevel switching utility
   for Isilon's FreeBSD-based OneFS product.

Zillow.com:

Software Development Engineer, Search & Maps team, June 2007 to
October 2008

 * Worked on Search & Maps functionality for web site in Java.
 * Developed change broker to queue and distribute updates and reduce
   load on SQL server instances in C++ on Linux.  This was a
   multithreaded server which queried back-end databases for updates,
   queued them (on disk with an in-memory cache) and responded to
   queries through an HTTP interface.

The Technical Committee:

Software Development Engineer (Contract), May 2006 to January 2007

 * Prototyped Linux server-side implementation of Microsoft's LSA-RPC
   protocol in C++ in order to verify Microsoft's protocol documentation.

Amazon.com:

Software Development Engineer for Financial Systems, January 2005 to
May 2006

 * Developed and maintained software handling Amazon's accounting
   systems, using C++, Perl and SQL (Oracle).

Microsoft:

SDE Intern for Windows CE, Summer 2003

 * Developed USB function drivers and boot loader for AMD Alchemy
   Au1550 MIPS32 microcontroller.

Microsoft:

SDE Intern for Visual C++, Summer 2002

 * Modified the Visual C++ back-end to optimize in parallel on SMP
   machines at per-function granularity.

Education:

Cornell University, College of Engineering
B.S. in Computer Science, Class of 2004

Personal Projects:

 * Developed a minimalist package manager to support custom Linux
   distribution.  Original version written in Perl in 2005; rewritten
   in C in 2008.  The C version can do a streaming install of new
   packages from stdin, suitable for piping wget through during a
   network boot/install, using under 64K of heap and no temporary disk
   space in excess of that needed by the package itself.

 * Bug-fixes to get recent Linux kernel versions (2.6.26.1 at the
   moment) to boot on Sun E4500 server.  This involved fixing a race
   condition in the SMP startup code which caused the non-boot
   processors to try to make OpenPROM calls using the same parameter
   buffer, and only manifested with high CPU counts (3 or more in
   theory, not observed in practice with fewer than 5), and modifying
   the TILO boot loader to support larger boot images.  There were
   also some minor tweaks needed to make interrupt handling on the PCI
   I/O board work.  My SMP startup bug-fixes were recently accepted
   into the kernel source tree.

 * Ported Cyclades PC300 T1 line card Linux driver to UltraSPARC and
   modified it to work on recent kernels.  This involved rewriting
   portions of the driver to work with the newer version of the kernel
   HDLC layer in 2.6.3 and later, editing for 64-bit cleanliness and
   rewriting the management of buffers in the card's on-board memory
   for improved performance. (April 2005)
