Sears Holdings Corporation

Chief Architect / Technology Consultant

Built a Hadoop cluster in a broad effort to store and process massive amounts of data that had previously been scattered across the company and otherwise unavailable for meaningful realtime and near-realtime analytics. Drove the internal development of agile map/reduce programming practices and led a team to quickly deliver powerful and cost-effective big data results using Hadoop and Ruby.

As chief architect, designed and built a private cloud spanning multiple datacenters based on open source software including Linux and Xen. The initial focus of the cloud and the early production rollout was centered around virtual desktops with clients in a variety of locations around the country and world. The second target was large-scale server virtualization featuring self-service in a leading-edge endeavor.

Designed and implemented an automated build process for Red Hat and CentOS Linux servers that allowed for quick deployment and large-scale system rollouts. This effort supported mass migrations from proprietary UNIX systems such as Solaris, AIX, and HP/UX as well as large-scale horizontally spread internet applications.

As part of the Sears Holdings Corporation insourcing back from CSC, responsible for the migration of Solaris servers from CSC data centers to SHC data centers.

Supported a UNIX environment composed of over 300 Solaris servers and 200 Linux servers located across the country. Accomplished this with the aid of tools and processes that had been designed and developed previously while an employee of Sears (see further below).

Sears, Roebuck, and Co.

Senior UNIX Systems Engineer

Supported a UNIX environment composed of over 100 Solaris servers across all business units. As the senior engineer, responsible for designing, creating, and supporting all tools used to accomplish this.

Finalist for annual Chairman's Award for Innovation for the creation of a suite of web-based applications that perform systems availability and performance monitoring, page/alert notification and logging, system capacity planning, patch checking, security vulnerability logging, and team document management. The applications were built with purely free software including Apache, Nagios, PostgreSQL, MySQL, Ruby, and Python.

Created a robust mechanism for the build, update, and synchronization of software packages across all servers that were supported. This allowed for a standardized environment across the enterprise. Over 40 required software packages, including gcc, perl, rsync, and sudo, were installed by this method.

Along with the operating system, supported the company intranet environment which utilized both Apache and Netscape web server software to provide over 250 sites.

System Software Associates
