I'm an IT Generalist with over 15 years of experience managing Windows, Linux, UNIX, and Macintosh systems. This means that I tend to work in the cracks in the organizations that hire me: I get between systems that don't talk to each other, and make them talk. I work between the IT department and other departments to find out what everybody needs, and then build solutions that make everybody's day better. I even work inside of the IT department to get sub-groups that don't work well with each other (for instance, system administration and networking often have issues), and help them resolve their issues.
Because of this, I find myself working heavily with systems automation, and I take great joy in helping somebody remove hours of repetitive work from their work days, regardless of what department they work for, or what they do. Making someone's work life better is the point of technology, after all.
I am comfortable in a wide range of working conditions. Work environments have been heterogeneous (Windows, OSX, and several flavors of Linux), small to medium sized (from 10 to 120 servers, 20 to 300 workstations), and mixed locations (all local to all remote teams).
- Open Source Software Contributions2002-Current
- Starting in 2009, I began participating in the TurboGears project, working primarily on the documentation. In 2011, I took over as project maintainer, and we put out three releases in that year alone.
- Created Java plugin for Openfire XMPP server, allowing vBulletin forums to have a working XMPP server for their communities.
- Contributed patch to Mercurial to assist with repository conversions. Specifically, it allows branches to be renamed (useful for repositories that used named branches in Subversion to change their main trunk location).
- Implemented initial Pluggable Authentication Module support for HylaFax, which was accepted into HylaFax 4.2.0.
- Contributed code to MythTV project, allowing users to save recordings using custom cut lists, which allowed for easy removal of commercials.
- Contributed documentation to WebGUI project, showing how to design a custom theme for WebGUI.
- Contributed documentation to libpqxx project, showing how to compile libpqxx using MinGW/MSys on Windows.
- Choopa.comSayreville, NJDeveloper2012
As a developer at Constant.com (renamed from Choopa.com in Jan, 2012), I have worked with a variety of technologies, with the heaviest focus being on OpenStack and Nagios. I have helped bring two products to production level availability for their customers (specifically: the Dedicated Cloud Server and Backup systems).
- Developed interface library to allow internal systems to manage OpenStack nodes, and gather billing information from them.
- Configured Bacula backup system as replacement for custom backup scripts.

- 6th Avenue ElectronicsSpringfield, NJSystems Administrator, IT Generalist2005-2008, 2011
In 2007, 6th Avenue began switching from their then-current POS system (named Tyler) to SAP. At the end of 2010, SAP was declared unworkable, and I was asked to come back to help them switch back to Tyler.
The environment at 6th Avenue covered a wide range of platforms spread out over 120 servers (both physical and virtual). We had VMWare ESX, Windows Server 2003, Windows Server 2008, CentOS Linux, Suse Linux, and Debian GNU/Linux. In 2011, I was brought back to transition the POS system and become the IT Manager. At the time the POS transition was completed, we had a team of 6 people managing the servers and about 300 desktops.

- Datapipe, Inc.Jersey City, NJUNIX Developer2008-2011
Datapipe manages thousands of customers servers. Many of these servers are connected to various shared storage systems, including 3Par, Isilon, and backup servers. Datapipe required an ability to do reporting on what data was being stored on these systems for each client, and then report that data back to billing. In addition, Datapipe required monitoring of the backup systems to ensure timely and complete backups of client data. My duties primarily focused on making these systems work well.
My team structure is worth describing briefly as well: My immediate manager worked out of Austin, TX. One coworker worked in the same building as myself, and I had two "extended" teammates who worked in Jersey City (I worked in Somerset). The extended team included the Windows developers, while I was on the UNIX development team.
- Created new backup monitoring and reporting system called StorageWeb, enabling a new revenue stream for Datapipe.
- Developed a system called unixops to allow Datapipe technicians to use one time ssh keys for accessing client machines as needed.
- Developed multi-threaded back end daemon which connected to the various storage systems and gathered the data about the stored data for reporting before pushing aggregate data to the billing system.
- Developed web interface that would allow users to drill down and see how storage was being used (by client, by server, by data center, and/or by storage type).
- Wrote tool to gather performance data from 3Par InServ nodes and display it via the client portal.
- Optimized PostgreSQL database on FreeBSD. Multi-million record insert jobs were taking hours to complete, and the optimization brought that time down to 20 minutes.
- Updated and maintained the existing backup monitoring tool which reported backup failures to our main ticketing system.

- SAP to Tyler Conversion
Period 2011 Company 6th Avenue Electronics Tools AutoIt3, CentOS Linux, Python Platform Server: CentOS Linux, Client: Windows
6th Avenue Electronics found that SAP was not a workable solution for them. The decision was made to switch back to the Tyler POS system. They would do a new installation, though, so that mistakes made with the old system could be removed, and the system could be more easily maintained. I was tapped to manage many of the technical aspects of the migration, while my immediate managers would handle the business aspects.
Due to the costs associated with SAP, we had just over three months, in total, to complete the transition. We were successful.
- Wrote several one-off scripts to check data that was sent in various Excel spreadsheets. Validate that all entries in column A of File 1/Sheet 1 are in Column C of File 2/Sheet 1.
- Used AutoIt3 to automate the update of several items that could only be keyed into the client. No import existed at all. This reduced work from several hours down to an hour (including the initial script creation).
- Developed an automated installer that was used to handle installing all components (receipt printer, fonts, initial configuration) on every machine in the company.
- Worked with Tyler Retail Systems to configure the server properly.
- Developed snapshot backup strategy that reduces downtime for Tyler to mere minutes per night.
Period 2010 Company Datapipe Tools FreeBSD, Python, Apache, PostgreSQL, TurboGears Platform FreeBSD, Web Browser
Datapipe manages thousands of servers. Many of these servers are connected to various shared storage systems, including 3Par, Isilon, and backup servers. Datapipe required an ability to do reporting on what data was being stored on these systems for each client, and then report that data back to billing. StorageWeb was written to fill that need.
- Debugged issues with Python, FreeBSD, Apache, and modwsgi. Turned out to require specific compilation options to get these all working correctly.
- Developed web interface that would allow users to drill down and see how the storage was being used (by client, by server, by data center, by storage type).
- Developed multi-threaded backend daemon which connected to the various storage systems and gathered the data about the stored data for reporting.
- Developed backend daemon that pushed aggregate data to the billing system, allowing billing to finally happen for all clients.
- PyTyler - Tyler POS to PostgreSQL Migration Tool
Period 2007, 2011 Company 6th Avenue Electronics Tools Python, PostgreSQL, Tyler POS System Platform HP-UX, Debian GNU/Linux
Tyler is a point of sale system used by many smaller retail establishments. Tyler stores data in a set of proprietary ISAM files. These files do not have a modern access tool available (such as Crystal Reports) to perform reporting.
The users needed an easy way to report on the data, and this meant a tool was needed to copy the data from the on-disk files into a formal SQL server of some variety. In less than a month, I wrote a tool in Python to read the Tyler data files and load the information into a PostgreSQL database on a nightly basis.
This tool copied the entire database, comprising approximately 36,000,000 records, 140 tables, and 22 gigabytes of disk space. The program worked by reading the structure definition from the configuration files and recreating the structure in PostgreSQL. PyTyler would then read each table, row by row, parse the data in the row, and load it into PostgreSQL server.
This allowed the users to use standard ODBC drivers to access and report on the data.
- Developed a tool to read configuration of ISAM files, and generate SQL "create table" statements mirroring the structure of the file.
- Created a specialized reader class which could read the data stored in the ISAM table.
- Developed small web server application to provide status page for administrators while migration tool runs
- Reduced total run time from 13 hours to 5 hours by converting the entire application into a multi-threaded application.
- Verified that data is being copied into the system correctly.
- Tyler POS system was in production until the closure of the company in December, 2011, so data copy ran every night to bring in updated data from previous day's activities.
- SBN Implementation
Period 2004-2005 Company Diversified Systems Tools SBN, Sybase 11.0, PHP Platform Microsoft Windows 2000, Debian GNU/Linux
SBN, published by IBSoft, is an ERP system for the alarm industry. Diversified Systems is a subcontractor working in the low voltage electrical industry, including alarm systems, stereo systems, central intercom systems, structured wiring, and central vacuum systems. I implemented all aspects of SBN at Diversified Systems.
The provided client interface was unsuited for the intended use. This resulted in much in-house development to augment the SBN client with a web-based interface.
- Configured all aspects of SBN from base installation to full production mode, with active communication with users at each step.
- Implemented over 50 custom screens and reports using PHP on an Apache web server. This included easier access to customer searches, more usable technician schedules, and easier input for large quantities of data.
- Developed automated system for the sending of faxes to field technicians,saving over 5 work hours per day.
- Implemented an automated backup system for the database.
- Administered Sybase instance on day to day basis, resolving issues with full log files, etc.

- Installed and configured iSCSI based SAN disks.
- Installed and configured all aspects of VMWare Virtual Center and VMWare Virtual Infrastructure 3.
- Developed (and tested) virtual machine templates to allow rapid deployment of new virtual servers using various operating systems (Windows XP, Windows 2003, Debian GNU/Linux, RedHat Linux).
- Monitored daily usage of VMWare hosts.
- SQL-Ledger Implementation
Period 2005 Company Diversified Systems Tools Perl, Apache Platform Apache, Debian GNU/Linux
- Authored script to automatically migrate necessary data (customers, bills to be collected, etc.) from SBN to SQL-Ledger.
- Installed and configured SQL-Ledger.
Period 2001-2002 Company Ciber, Inc., contracted to IBM Tools Perl, Cygwin, GNU Make Platform Server: AIX, Client: Windows NT
IBM was under contract to develop a complete clinical information system for Kaiser Permanente clinics. I participated as a member of the environment team, focusing on improving the build processes.
- Resolved issues with corrupted builds occurring weekly, resulting in savings of over 1000 work hours every week.
- Developed and improved approximately 450 compilation scripts and Makefiles on AIX and Windows NT/2000, fixing dependency issues and allowing reliable use of nightly code compilations.
- Evaluated, tested, integrated, and deployed new compilation tools.
