• Technologies: Visual Studio 2010 64 bit cross compiler, UEFI Framework, ITP, Arium, DediProg for programming ROM chips, Rational Jazz for workflow management, Rational Clear Case, Clear Quest and CMVC for code management, Agile method for project/team management.
• Worked as a developer and project integration team member on just released IBM EX5 flexible, scalable, high end systems. Specifically worked on the areas of System Management Interrupt SMI , and Memory on Intel's Stoutland Platform with Nehalem and Westmere processors.
• Worked on the board bring up of the new Intel's Romley Platform and SandyBridge Processor for new in development IBM servers and blades. I was responsible for USB Module and CSM Modules to the CORE UEFI 1.2 .
• Worked as a firmware developer UEFI Post/Bios for IBM x86 Servers, specifically looking into Legacy and UEFI firmware for USB and Compatibility Service Module subsystem CSM . Worked on challenging critical problems CRIT-SIT for the customers of Intel's Thurley based IBM's x86 servers specifically in the areas of USB.

• Formulation, design, and development of a new simplified preload process that saves time and money. This new process is a pluggable step in a manufacturing framework. It is cross-OS Windows/Linux and cross-platform Intel/PPC/AMD . This new preload led to saving of 500K and has been rolled out in worldwide production sites including Mexico, Brazil, China Hungary, Taiwan and US.
• Software maintenance of Preload Tools in Legacy DOS and Linux environment.
• Worked as Preload Engineer for World-Wide IBM Intel x86 test processes. Preload is a definite activity in the manufacturing process where a previously developed operating system image is put on the machine's hard drive. Once the image is laid on the hard drive further personalization and customization is performed. In 2009 around 130,000 machines were preloaded. The specific work done for his are
• Technologies: UML, Design Patterns, C , Python, Java, WINPE, Bash, Linux, PXE, DHCP, FTP, TFTP.
• Developed customized network bootable Linux and WINPE Images PXE Images for test in manufacturing various Appliance Servers like IBM Smart Cube Server, Schooner Appliance. It had to meet the benchmark test of simultaneous network booting on 15 Servers, Linux or WINPE 80M OS Image over a network and run specialized tests.
• Technologies: BASH Scripting, Python, Linux and associated tools to develop initial ramdisk, and Kernel, x86 assembly, DHCP, TFTP, WINPE and associated tools
• Architected, a semi-automated, robust e2e solution for a key large enterprise client that allows for unit-of-one customization based on customer data provided at time of order. Direct savings of having to process orders is estimated between 50-70/unit which in turn yielded 28-55K of increased profit based on 2008 volumes. Value is also seen in reduced order problems automation versus manual improved SLA. Additional value has been realized in applying the capability to meet other client's needs i.e. Ford, GM, Shell accts have similar requirements on IBM x86 products .
• X3 is a cross-brand, cross-architecture IA-64, IA-32, and AMD64-Hammer and cross-platform EFI, Linux, WIN PE manufacturing framework. Designed and developed an executor which works on PXE booted OS Linux, DOS, EFI and Windows/WINPE executing various commands on System Under Test. Developed Server based User Interface Monitor.
• Technologies: Visual C , GNU C , Python , Linux, Windows, Java 2.0, JavaScript, XML, XSLT.
• Developed the manufacturing context for 64-bit Intel arch that includes a new firmware layer Extended Firmware Interface or EFI that provides a standard environment for running pre-boot applications and booting an operating system. The specific work done for this was:
• 1. Designed and developed network boot efi-shell with ram disk, a TCP/IP driver, and the ability to setup an initial environment from Windows NT Server on to 64 Bit machine using Preboot Execution Environment PXE . The network boot EFI-Shell installs the TCP/IP driver and sets up the network connectivity to the Server to network boot Linux OS.
• 2. Developed User Interface Monitor on the server.
• Technologies: Windows Itanium C/C Cross Compiler and SDK, EFI toolkit, Python, GNU C .
• Worked as a designer and developer for various tactical and strategic manufacturing tools like

1. Mail Server of Secure Image Distribution System over Internet SIDS .
2. Phoenix, a tool to generate bar code,
3. Ship Group Prep Order Monitor, a tactical solution intended to control the kitting of dynamic ship groups in parallel with the assembly of the system units in other systems.
4. L1 Performance Monitor to constantly monitor a set of 60 to 100 machines being manufactured.
5. Parts Entitlement Warranty PEW , a tactical solution for IBM Direct product to big customers for finished goods inventory environment.
