The company depends on this system daily to manage hundreds of millions of dollars worth of deals where even small errors would mean millions of dollars of risk, while giving the company a unique automated capability and advantage in the marketplace.

August 2000 - June 2001 |
Server Development, Portalvision.
Responsibilities include server code development
in C++ and some Java on the Solaris platform. Also responsible for technical
knowledge and integration of Internet technologies such as Apache, Jserv, GnuJSP,
and NNTP(INN) into the Portalvision server system. The core Portalvision server
uses a message passing interface over middleware to facilitate this
distributed and highly scalable platform. I re-architected and re-factored
the Instant Messaging server code from C based code into an
Object Oriented C++ implementation that greatly reduces bugs and facilitates
verifiable correctness and future code maintenance. I designed and implemented a distributed
and cached headline server which allows for news and messages to be sent to the client
platform based on user subscriptions, allowing for different priorities of
messages and delayed start and expiration dates. I researched technology for,
designed, and implemented a message board server system which allows for
scalability, integrated it into the Portalvision server security framework,
yet leveraged the open source INN server to allow for very rapid implementation.
I delivered all of these projects on time on very aggressive schedules. I used
UML (especially sequence diagrams) to document these projects. I developed a reputation for new creative ideas for future features that would provide compelling value for Portalvision and could be implemented with technologies I researched on my own time. While working aggressively to successfully meet the delivery date of the message board server, on my own time and initiative I did a prototype implementation of one of those ideas to the delight and surprise of the Portalvision executives. At the CEO's request I then implemented a custom version of the prototype for demonstration to one of our bigger potential partners as a vision of what future value Portalvision can provide to partner companies above its current capabilities. Management was considering me to head a future research department. |
