Fritzler has spent his entire career in the start-up environment, working in a variety of funding and entrepreneurial conditions. His in-depth technical experience includes instant messaging, digital signal processing, and wireless/cell infrastructure. Fritzler developed DSP simulation and instruction set transcoding software for TerraFone, Inc.'s prototype Voice over IP solution in 1999 after leaving a small network engineering consultancy earlier that year. He moved to ActiveBuddy, Inc. (now Conversagent) where his familiarity with instant messaging networks enabled early integration with AOL Instant Messenger. The distributed cluster architecture Fritzler helped to develop allowed ActiveBuddy to support millions of instant messaging users on the SmarterChild agent. Fritzler later moved on to VivoTech, Inc., where he worked on RFID-based payment solutions.

Fritzler has also contributed significantly in both time and code to the Free Software community with such projects as imdsr (a wireless messaging aggregator and router), intermobi (a TCP/IP stack for the RIM handheld allowing direct connection to the Internet from your hand), timps (an instant messaging-centric proxy server), and, most famously, libfaim (a reverse-engineered reimplementation of the AOL Instant Messenger protocol).

Fritzler spent the first half of 2005 in Iraq and the Emirate of Dubai deploying satellite-based Internet systems and Voice over IP solutions for the United States Army, the Coalition forces, and their subcontractors. He is now back in San Francisco working as a consultant in the areas of software and operations engineering for a variety of startups.

Like every other resident of San Francisco, I have pretensions of being a photographer. Which mostly means I spend a lot of time trying and a lot of money on really clear glass encased in nifty cylindrical widgets which I then spend a lot of time trying to keep clean.

I enjoy mountains and deserts, aircraft and airports, and anything from the air. Email me for prints, usage rights, or if you want to give me a free ride into the air, desert, or mountains.

I'm always eager for conversation about:

• Aviation
• Photography
• California
• Geology
• Roads and Transit
• Corny Douglas Coupland references, because that's what he's all about.

• I maintain a personal LiveJournal/"blog" here (rss).
• I make myself seem smart with my photograph-oriented blog (rss).
• I am always finding new typos to fix in Wikipedia, and, from time to time, contribute my own view of the universe. My user page is here.
