● Architected and implemented IBM Cognos TM1 consolidation and reporting cubes, allowing the Finance Team to roll up 6 different operating company charts of accounts and financial data into a single EBITDA report. This system also allowed budget allocations to be projected down into the constituent company's charts of accounts. Each company had different implementation of fiscal calendars, accounting periods, and payroll processes. Extended this system for KPI reporting and feeding as a source of truth for Microsoft SSAS cubes, with drilldown reporting capabilities.● Architected, deployed, and supported a cloud-based Alfresco Document Management 2-tier HA cluster (migrated from an existing single 32-bit instance with no user downtime). The system supported 10,000+ document images ingested, classified, and indexed per day for multiple years. This system provided the HR and Finance teams with indexed and referenceable documents and workflows to support discussion, delivery, and archiving.● Architected, implemented and supported a GitOps ETL process using Pentaho Data Integration and Microsoft SSIS to extract and transform data into an Anchor Model Master Data Warehouse (6th Normal Form).

Consultant for several long term projects, including: ♦ Design data center, and configure servers (AAA, email, news, http, ftp, etc) for several regional ISPs, from a few analog lines to several dozen PRIs ♦ Consulting for several industries such as Medical, Retail, Real Estate, Insurance, Utilities, and Legal offices. Services included line of business database, email, file and print server maintenance, network wide upgrades, backup provisioning and testing. Provisioning included network backbone and campus wiring, digital PRI tandem Class 5 to key system (Option 11e, Mitel, Executone, etc.) service allowing protocol mapping, call routing management, voicemail to email attachments, email to paging gateway (TAP/FLEX) service provided by Intel 486 servers running Asterisk on Linux. ♦ OpenVPN mesh overlay network for the region using OpenWRT, across all service providers for service performance recording (using MRTG), troubleshooting, technician dispatch, and failover to cellular service if needed. Features were managed as individual cost options and prepaid service discounts. ♦ Industrial quality DNS subscription service replicated across the region. This service was capable of scheduling DNS updates to the second (both server side, and client side TTLs), to allow completely transparent global updates to the zones managed. This also included access to the TLD servers via API for direct registration and updates of domain registration records. (using djbdns and OpenSRS) ♦ A backup SMTP service capable of backup MX spooling and resubmitting hundreds of thousands of emails using ESMTP pipelining, allowing network and IP service outages to be transparent to business correspondence and provide minimum latency for delivery interruptions. ♦ Migrating satellite weather downlink from SCO Xenix/286 to a Linux machine, using binary emulation and custom serial hardware.

Brought up a digital-first, TCP/IP native Internet Service Provider using "Official" Red Hat LiNUX 3.0.3 (Picasso) and a commercial Red Hat Support Network subscription (eventually became RedHat Satellite). This OS was installed on Intel and DEC Alpha machines in the NOC for support.Founded several local users groups (e.g., Lafix - the Lafayette Linux Users Group) to provide training and support in Linux and internet tools. The training in HTML, PHP/fi, Apache, FTP, email, faxing helped create several "Web Design" and consulting businesses, some of which are still in operation into the 2020s (e.g., Firefly Marketing Solutions, Rader Solutions).

Brought the first take-all-comers ISP to the 318 area code, from an existing multi-line Novell 3.11 based Bulletin Board System (BBS) a FIDOnet Net 3803 (Terrabyte BBS) peer, UUCP relay, and BBS Door terminal server for telnet, gopher, and FTP. After a migration to Novell 4 and addition of a SLIP NLM, the system became a full TCP/IP gateway for subscribed dial-up users.The local RBOC partnered to provision the first commercial Internet broadband connection (channelized DS1, aka T1) in Lafayette with Sprint Communications. This became Lafayette's first non-academic, locally hosted Internet Service Provider, and the first provider with a local 318 (eventually 337) dial-up number for Lafayette residents and businesses.Once Cisco 250x equipment became available for terminal servers, the system migrated from individual US Robotics modems to a US Robotics Modem Rack (supplied by Cisco), and eventually SIMM based DSP cards. This service became a SLIP/PPP native TCP/IP dial-up Internet Service Provider. A Slackware/SLS 1.00 (from 24 3.5" floppies, provided by Patrick Volkerding personally) with a 3COM 3c501 thinnet ethernet adapter was provisioned for TACACS+, httpd (first Cern httpd, then the patched one, aka Apache httpd) for ~home page service (eventually adding PHP/fi), NNTP, SMTP, POP3, bind (DNS), telnet and finger services.When Livingston digital terminal servers became available, a migration to PRI signaling was completed for a completely digital path from user to the IP backbone. As Livingston RADIUS was on the IETF Standards Track (eventually RFC2138) and had better accounting support than TACACS+, the AAA service was migrated. This provided ISDN BRI 2B+D service to capable clients, and supported MPPP across terminal servers, for channel bonding (aka Multilink).
