2016: Infrastructure as a Service (IAAS) and Application Architecture:

Client requested upgrade of a legacy system for an organization that engages potential voters in U.S. elections across dozens of campaigns. Migrated to a full virtualized IAAS microservices architecture with virtual firewalls, virtual LANs, and virtual DEV/TEST/PROD servers. Negotiated contract for service, did load testing to predict needed allocation of resources, and led team for a successful roll-out, and hosted solution.

Originally setup in MySQL and moved to MariaDB

Consultant for a hospital network that spanned 4 states, 20 hospitals and numerous outpatient facilities and clinics.

Called in to take over networking issues that prior consultants were unable to solve.

After purchasing two competitors, the client was required to maintain connections to the internet and required by vendors have direct WAN connections to 3 third-party vendor networks.

Client had a complex routing issue consisting of multiple Cisco routers, multiple digital lines, managed switches, fiber repeaters, a satellite connection, and the local network.

Back before the days of ipcop, smoothwall, endian, PFSense, and other pre-built systems; linux firewalls were built with ipchains and/or iptables.

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.

Optometrist had two offices each sharing one accounting database. Client wanted a secure and easy way to network each office such that all computers on each network could access the other network without installing specialized hardware or software. I met with clients and proposed and implemented a low-cost, high-resilient system. Directed office IT on required internet purchases and led the installation of a trouble-free, web-managed system consisting of two Linux firewalls using VPN IPSEC software.
