Full-time commercial airline pilot

1999-2002

President & Chief Technology Officer
WARP Solutions, Inc

  • Managed a development team of 40 people, including teams in the USA, Russia and India.

  • Invented, Designed & Developed the Patented WARP Load Balancer application, including Kernel-level, TCP/IP driver needed to intercept requests and redirect them to the least loaded server. The kernel driver is multi-threaded, common-code multi-platform driver that runs on Linux, Windows, and MacOS X.

  • The WARP Load Balancer is the only one in the industry that is completely peer-to-peer, where the decisions are distributed to all nodes, with no central load balancer device, allowing unparalleled scalability. WARP Load Balancer is written using C++ and Java/Swing GUI.

  • Designed & Architected the WARP Content Distributor, which has the ability to distribute content to a server cluster, and communicate with the WARP Load Balancer in real-time to atomically "switch over" to the new content. WARP Content Distributor is written in C++, with a Java/Swing GUI and J2EE back-end.

  • Invented & Architected the Distributed Database Transaction Clusters, similar in features to the Oracle Real Application Clusters, but using a different approach that drops the requirement for Database Vendor Support.

Sr. Architecture Consultant

Bear Stearns

  • Strike Electronics Communications Network.

  • Created a Web front-end to Strike ECN (Electronic Communications Network) using Java Applet and a back-end J2EE-based infrastructure using BEA WebLogic Server.
