To Whom It May Concern:

My background includes many facets that would be a benefit to the organization. Below is an overview of my background and the projects I have been involved with. My resume should show my level of technical expertise broad project involvement.

In 2005 I was tapped as a developer to begin a large project to upgrade and expand Northern Arizona University’s learning management system. The old system was Perl based and was just one big single point of failure. We upgraded to a multi-node, fault-tolerant, high available system. This system is still currently in use but a new upgrade is in process to the latest generation of the product line. My team oversaw both upgrades and configuration of servers, storage, databases and networking. We also wrote all new integrations to tie this new enterprise system together with PeopleSoft, LDAP and other internal and external systems.

The project was a success and we continued maintenance, upgrades, with new integrations and features. Working with other groups around campus we have grown and added value to the system. Watching this growth has been very rewarding. This service has grown to 7 nodes and serves over 6,000,000 daily page views to over 67,000 users, backed by a 2TB Oracle database. We expect the new replacement system to grow even faster.

Another large part of this current assignment was to create an enrollment management bus across campus. This system is fed by information from authoritative systems on campus. These systems include PeopleSoft and LDAP among others. The system allows us to overlay modifications to this data, apply our business logic and then send it to multiple endpoints. This includes any number of learning management systems and other applications. This is a pluggable and scalable system. This process was originally created in Java and converted over to Python. The application communicates with other applications in a multitude of ways including SOAP and RESTful web services, direct database API or whatever the target service requires. The next version of this application will be exclusively event driven and is now under development.

I also handle other web development for whatever needs pop up in our academic computing department. These applications were written in Java, PHP, and .net. Applications range from simple WordPress blog customizations to high available, distributed, complex web applications.

Throughout all of these major projects I have handled big picture elements all the way to installing and configuring iSCSI storage area networks to pulling cable in the data center.  This gives me a unique set of experiences that allows me to see details in big picture problems.

Thanks for the opportunity!
