2008-2010, Lenovo RTP, NC

2. Software Architect
• Designed an automated process for dynamically capturing and redeploying customized operating system images
in a high volume manufacturing environment. This process saved an average of 1.2 million dollars of global
manufacturing time annually.
• Designed a cross platform build system capable of building software for arbitrary platforms and source
languages. This system included a fully MVC PHP web based front end for user interaction and control over the
build and distribution process.
• Directed engineers from various development groups in the design and implementation of web services capable
of real-time software configuration information to a globally distributed manufacturing environment.
• Designed and implemented multiple programming languages and interpreters thereof to facilitate large scale cross
platform process automation.
• Directed several enterprise software systems through the software development life cycle.
• Designed optimized relational databases in support of manufacturing software configuration systems.
• Supervised the integration of Agile methodologies to the development process of the manufacturing software
engineering group.
• Lead an international team of software engineers providing infrastructure and automation support to the global
manufacturing process.
2005-2008, Lenovo RTP, NC
Senior Software Engineer
• Designed and implemented PXE based test processes complete with customized boot loaders, DOS/Linux/WinPE
operating system images, and a cross platform proprietary control system capable of controlling processes across
all three operating systems.
• Increased efficiency of legacy manufacturing processes by designing solutions incorporating the implementation
of existing 16-bit system level utilities to 32-bit utilities for Windows and Linux.
• Worked closely with various development teams to facilitate the design and implementation of a unified set of
manufacturing platforms and processes for the introduction of Microsoft's Vista Operating System.
• Administered Windows and Linux based servers. Configured custom Linux kernels and developed the associated
manufacturing Linux images for use in Linux operating system preloads.
• Developed a family of eclipse plug-ins (in Java) providing IDE support for assembly language programming
(supporting A86, NASM, MASM, and GAS).
• Worked closely with senior software engineers at Microsoft to ensure manufacturing processes for all Windows
operating systems functioned as expected. This frequently entailed the creation of new software to support a
combination of new hardware and software requirements.
• Designed and implemented a custom continuous integration solution providing quality assurance and automated
distribution of software in support of global manufacturing processes.
• Refactored the windows boot loader to support PXE booting the Windows Pre-installation Environement.

Generally, creating a system that responded automatically to formatted emails by initiating targeted file transfers
via secured FTP to one or more specific global manufacturing sites.
• Administered a large number of Windows, Linux, and Solaris servers in support of global manufacturing
operations.
• Designed and implemented a configure to order system providing the global manufacturing environment to
support customized product builds at any scale.
• Ported a suite of legacy 16 bit DOS manufacturing utilites, for use in manufacturing, to 32 bit Windows and
Linux environments.
• Designed and implemented a manufacturing process providing support for the installation and configuration of
multi-boot systems in the manufacturing environment.
