Massive data stream absorption

Customer had a Java/Tomcat/Apache/MySQL application that was unable to absorb real-time GPS probe point data from millions of vehicles without choking. Vendor sending the real-time GPS data would get errors and stop the feed.  Lead programmer for application insisted that the only way to fix the issue was to "upgrade to 'Enterprise class' software like WebSphere and Oracle" 

WAN Load Analysis for 10 Distributed Offices

Analysis of web server, network and firewall security for client with 10 offices across the Midwest. Issues investigated included: connectivity across multiple T1 lines, migration from Novel to a Windows 2000 cluster, general IP security, database issues and IT security.

Implemented MRTG, DMZ, new routing tables, secondary firewall with an IDS (snort), dual Internet connections with bandwidth sharing. Client passed multiple, third-party, security audits and passed with no issues relevant to work done.

Enterprise Migration to Tapeless Backup System via incremental Rsync and deduplication

Client had 7 offices each connected via a T1. Each office had a Windows 2003 server with nightly backups via tape. Each system had roughly 100 Gigabyes of data to backup. Existing issues were that complete automation was impossible because individual office managers had to replace tapes, recovery was slow and required searching individual  tapes for the correct data, and the high cost of gigabyte tapes.

Web-based Traffic Management System managing real-time data from roadside devices

Worked with embedded device team to create a vertically integrated system from field devices to server system to end user. Part of the investigation was looking at raw TCP/IP to generate minimal HTTP requests to minimize network traffic from the numerous, mobile-connected devices. 

Investigated technologies and built from scratch web-system used to manage of deployment, monitoring, reporting, TFTP updates, calculations, and real-time display of data from sensors deployed along roads and connected via mobile traffic.
