Devon IT
Consultant/contractor reporting to CTO

I was brought on to do product management for the Devon Connection Manager. The Connection Manager provisions and manages connections between thin clients and blades using Teradici chips that provide a high quality remote desktop experience. After doing initial roadmaps etc, I did development work to help bring the product to initial release and to ensure everything was covered.

• Initial product roadmap, admin web interface prototype, initial administrator visible component specifications
• Critique of partner products and protocols (security, future capabilities, interoperability with networking)
• Designed and drove changes in partner product to drastically simplify initial setup and configuration for customers, resilience to network and administrative changes
• Got a wiki up and going (trac), put in lots of content that wasn't being recorded anywhere
• Architecture for the various components
• Protocol specifications for intercomponent communication
• Found numerous bugs in components, fixed some serious ones (C++, QT, strace, ltrace, valgrind, gdb)
• Implemented Apache module (C, Python), REST style public interface (text, JSON, XML)
• Implemented CLI talking to REST (Python)
• Implemented web administration interface talking to REST (Javascript, YUI toolkit) and admin components (Python, Genshi)
• Implemented an automated testing system linked to trac tickets to repeat bugs, catch regressions etc (Python, unittest, Selenium RC, Javascript)
• Implemented a single command product build system that produced a VMWare appliance as output (Python, ccache, VMWare Server, Ubuntu debootstrap)
• Implemented a control console application inside appliance (Python, whiptail)
• Implemented an automated tester with device emulators (Python, nlite Windows installation customization, VMWare Server)
• Implemented a core dump catcher which grabbed all relevant information into a dump file (eg open files, memory maps, core image) and build system component for getting backtraces (Python, gdb scripting)

Products:

Tarantella - Three-tier application broker

Tarantella is software that sits between an application server and a user with a web browser. It takes the application display protocol and provides a optimized display for the user. Additionally by acting as an intermediary it is possible to provide session suspend and resume, enhanced security, load balancing and similar functionality. I was the architect for the non-display side from inception through shipping, later taking on roles in sales, marketing and business development. The company renamed itself around this product. Version 1 was implemented in C++ with version 3 predominantly in Java. (Version 2 was just a marketing rebadge of version 1.)

VisionFS - SMB/CIFS server

Running on Unix, VisionFS was written from the ground up to provide Windows file and print services. It was written in C++ and was the first C++ project for our division. There was an extremely strong emphasis on ease of use and data integrity. Much of the framework code was later used to kickstart the Tarantella project. I was the architect and team lead from inception through shipping.

IXI Mosaic

Many enhancements to NCSA's Mosaic web browser to add (then original) features such as integration of help and preferences, client side scripting, drag and drop and URL links. Implemented in C with TCL scripting.
