Client had an emergency situation regarding a custom Windows .NET application that was an online store, a CRM system, an enterprise shipping/printing management system, and an employee management system.

Was able to immediately identify key security issues and attack vectors to stop ongoing attacks.

Assisted legal teams/law enforcement with chain of evidence and reports. Worked with legacy system code/server and client’s IT team to identify further weaknesses in system.

Led teams in multi-year process to modularize and replace legacy infrastructure without impacting business continuity. Upgrades included:

An Iowa Government department had an existing Microsoft Access project which needed to share data at multiple remote offices with some sites having an intermitent and/or slow dedicated connection.

Contracted by private regional hospital for assisting with security issues fpr network of several hundred windows 2000 client computers. Network ran with a central PDC running RedHat linux and Samba. Client was required to implement additional security as part of HIPAA (Health Insurance Portability and Accountability Act of 1996).

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.

A local real estate agency purchased a Perl-based commercial real-estate listing management package and purchased a commercial realty office management software that used Microsoft Access with a Visual Basic back end. Agency wanted to integrate those two products and expand on functionality of online version. Met with principles of agency, and setup deliverables, timeline and budget. Lead DBA and programmer for project able to exceed client expectations and setup a new data-driven website that agency claimed was responsible for becoming the dominant agency in the region.

Client had legacy Windows NT application (not connected to Internet, but running legacy system) that was running on VMWARE ESXi.

Client wanted to migrate to KVM/qemu however the old physical system had IDE emulation via Adaptec SCSI->IDE. And client had created the VMWARE emulation the same way. Thus when the VM was converted from VMWARE to KVM/qemu the system would not eboot. Got the infamous BSOD with "INACCESSIBLE BOOT DEVICE" error as it was looking for a SCSI drive controlled as IDE by an adaptec driver that didn't exist anymore.
