Objective
To practice the fine art of software development in a manner allowing for the evolution
of all involved parties and processes. I like making shrinkwrap Mac OS X software, working both on
developing an elegant and intuitive user experience, and solid under-the-hood foundations.
Work Experience
Senior Engineer: Smith Micro Software, Inc., Consumer Group
April 2008 to present
Software Engineer: Smith Micro Software, Inc., Consumer Group
June 2000 to April 2008
NB: I started at the company when it was named Aladdin Systems, Inc. In January 2004, Aladdin Systems, Inc. was
purchased by International Microcomputer Software, Inc. (IMSI), but remained a wholly owned subsidiary. In
July 2004, Aladdin Systems, Inc. changed its name to Allume Systems, Inc.. In July 2005, Smith Micro Software, Inc.
acquired Allume Systems, Inc. and while the "Allume" brand remains, technically Allume has been assumed into
Smith Micro and I am a SMSI employee. So, I've essentially worked for the same people for a long time, just
lots of corporate juggling about.
February 2008 - present
Working on my next project(s)...
Internet Cleanup 5
Released 6 February 2008.
Transitioned to using the same GUI as Spring Cleaning, which greatly simplified and improved our codebase
and the user experience of Internet Cleanup. Continued to evolve SpyAlert, making it more data-driven
and embedding Python as the mechanism to provide customized
logic.
Spring Cleaning 9
Released 21 February 2007.
Spring Cleaning 9 was a major rewrite of the product, and I was the primary for the project. We retired the
PowerPlant-codebase and rewrote the project mainly using the Cocoa frameworks. We redesigned the application
from the ground up to have a more flexible and expandable architecture, along with simplifying the
user experience. I was responsible for much of the core application design and infrastructure, as well
as generating some of the end tool and action plugins.
Internet Cleanup 4
Released 22 June 2006.
I was only minorly involved in Internet Cleanup 4's release, updating components like SpyAlert
and IM Log Cleaner. I was deeply involved in the rearchitecting of Spring Cleaning 9, so my energy
was focused there instead of here.
Spring Cleaning 8
Released 9 January 2006.
In Spring Cleaning 8, I created numerous new plugins: Music Finder search plugin, Image Finder
search plugin, Disk Image Finder search plugin, Archive Finder search plugin, Add to iTunes action
plugin, Import into iPhoto action plugin, Burn to Disc action plugin. The Font Finder plugin was
completely overhauled into the new Font File Finder plugin. Performed modernizations, updates, and
massive optimizations to the core file searching framework resulting in some big performance gains.
Internet Cleanup 3
Released 28 June 2005.
Internet Cleanup 3 was a major bit of work, since it was a complete ground-up rewrite
of the product. We wanted to rewrite using the Cocoa framework, and much of the GUI and
presentation logic is in Objective C and Cocoa. However I spent a good deal of time
developing our internal "Gonzo" library, a C++ Carbon/Core Foundation-based library of
engine code to help implement and drive much of the internal functionality of the product.
I was chief architect and implementor of Gonzo, and it's modern, flexible base is core
to much of what we'll be developing in the future.
Some application-specific bits of implemenation have been: a rewrite of SpyAlert, providing
a more thorough scanning for spyware and loggers; IM Log Cleaner; logging functionality;
working on core functionality (Gonzo); core threading issues; sheet and notification
managers and bottlenecks.
Spring Cleaning 7
Released 17 August 2004.
Spring Cleaning 7 was a tight release cycle that saw me implementing a means to save
Custom Search search configurations; removing Fat App Slimmer and Trim Fat; creating
the "Logs & Temporary Items Finder" plug-in; adding a custom dock tile menu to the
Spring Cleaning application; and fixing some long-standing bugs.
This product version also saw the introduction of the System Snapshot product, based
upon tripwire. I guess I'm responsible for bringing
open source to Allume, or at least bringing about Allume's first GPL product. The work
was performed by a buddy of mine and I was the liason/manager for the project between
him and Allume.
Internet Cleanup 2
Released 1 June 2004.
In the time since Internet Cleanup 1 and Spring Cleaning 6 were released, I worked on the
Internet Cleanup 1.1 release, and also a project that is as of this writing unreleased and
may never be released depending how things go. The project furthered my Cocoa skills,
use of "real" threads (pthreads via the QpThread framework), and improved my abilities
in ground-up application architecture.
For Internet Cleanup 2.0 my major tasks were creating the IM Log Finder plug-in, integrating
MailCleaner into Internet Cleanup (originally part of Spring Cleaning), updating SpyAlert,
adding table striping, windows saving and restoring their locations, adding a custom Dock
menu, many other GUI changes and improvements, some long-standing bugs were fixed, and
various internal changes (e.g. no more HeapManager so we can use direct Mac OS X memory
allocations).
Spring Cleaning 6
Released 6 June 2003.
Internet Cleanup 1
Released 10 June 2003.
My teammates were focused on NetBlockade, so a lot was left for me to focus on. I updated
to the StuffIt 7 SDK and switched to supporting StuffIt X archives. Created the Secure Delete
Action Plug-in. Added Preview support. Removed kind string cache and query OS directly.
Created SpyAlert plug-in. Created Language File Finder plug-in. Performing code changes
to establish Internet Cleanup's GUI and form.
I find myself enjoying object oriented thought and design. UML is a fun tool for brainstorming
and sketching out ideas. My Mac OS X developer skills are coming along as well. Getting
to work with Cocoa as well as Carbon.
StuffIt Deluxe 7.0.3
Released 9 April 2003.
Added tar archive support to ArchiveSearch.
StuffIt Deluxe 7.0
Released 19 September 2002.
Mostly an update for ArchiveSearch, adding Zip support, Unicode improvements, cleaning up some handling
of the archive searching logic.
Spring Cleaning 5
Released 20 May 2002.
Big project for Spring Cleaning 5 was writing FileSearch. Taking design patterns I started in ArchiveSearch
for "searching", I wrote a framework that abstracted the criteria and bridged the Carbon File Manager
implementations of searching for files on Mac OS. All core Spring Cleaning searches were rewired with
this FileSearch engine, and it lead to Search Plug-ins such as Custom Search. I also improved the GUI
support for drag and drop search contexts so the user could search folders. General Mac OS X support
improvements were also made. I found the work on FileSearch to have improved my framework architecting
skills; UML was a helpful tool during design, and my STL skills greatly improved.
StuffIt Deluxe 6.5
August 2001 - September 19, 2001 - v6.5
Updated ArchiveSearch to function properly under Mac OS X. ArchiveSearch 6.0 worked under Mac OS X but
had lots of problems (things broken, crashing, etc... hey, Mac OS X was still a beta OS when StuffIt
Deluxe 6.0 was released). This was just an effort to get it working and functional, no new features
added... that'll be in ArchiveSearch 7.
Spring Cleaning 3.5.1 & 4.0
October 2000 - 4 April 2001 - v3.5.1
October 2000 - 6 June 2001 - v4.0
My next project for Allume was Spring Cleaning. For v3.5.1 I helped with the effort to transition to
Carbon, mostly involving rewriting/translating Font Remover from it's Pascal heritage into C++. It was
an interesting project given what Font Remover does and the way Carbon considers fonts vs. how you could
poke around at fonts in "Classic". A learning experience all around. ;-)
After 3.5.1 shipped, my main project for 4.0 became the development of the Standard and Advanced modes
of operation. I lead the design and implementation of the feature, including the invention of the Standard
Mode GUI and revamp of the Advanced Mode -- all GUI savvy to the Mac OS X Aqua user experience. Converted
the alert system to the StandardAlert mechanism (SC, iClean, and all plugins). Added the preferences GUI
to iClean. The Standard/Advanced mode helped me to further explore notions of object-oriented software
development (design and implementation).
StuffIt Deluxe 6
June 2000 - October 2000 - v6.0
When I first joined Allume (back when it was Aladdin), my first project was ArchiveSearch 6.0.
I did not write the original spec, but did probably 90% of the coding on it. Fun experience.
Learned a great deal about writing multithreaded applications.
