GoFlight products originated from an idea I had to create a collection of affordable and aviation-focused computer peripheral modules for use with flight simulator software. The concept really took off! These modules are now used worldwide by flight schools, FBOs, flying clubs, commercial & recreational pilots, and aviation enthusiasts.In the first few years of operation, GoFlight had developed a loyal and enthusiastic following of repeat customers and generated millions of dollars in sales. The company won several industry awards for innovation in flight simulator hardware, most notably the "Bravo Zulu" award from AVSIM.com.

Back in early days of IM (think AOL Instant Messenger, Microsoft NetMeeting, and Napster), this Internet startup company was developing PC Java-based peer-to-peer social networking and file sharing software. I was a member of the development team and mainly worked on the auto-update component, which did version checking and updating of the app over the Internet. We integrated a VoIP conferencing component (code-named “MARS”) that was originally developed over at Intel Architecture Labs and later licensed to CenterSpan. I also did bits and pieces of the text chat, UI skinning, and peer-to-peer file transfer functions.

This was my favorite W-2 job ever. I had the honor of managing an extremely talented team of 5 employed and 2 contract engineers, and these guys made some of the coolest game control hardware and software the world has ever seen.
