2014.06 - 2023.10
- As a contractor for the Dept. of Veteran Affairs, I provided project management, support, and guidance for several mission critical enterprise projects, resulting in measurable improvements to releases and deployments of VBECS to its 120 blood banks, reducing the schedule from 5 weeks to a few days per site by optimizing the process and requesting installation code changes. Contributed to the Data Center process standardization and improvements, enabling a simplification to issue management resulting in faster and increased consistency for issue resolution times.
- I've also managed the projects, HW upgrades and deployments for the UNIX and cluster teams, coordinating efforts with other enterprise teams of storage, vmware virtualization and database teams.
- Participated in many mission critical incidents, working with and coordinating the enterprise teams to root cause and resolve outages and performance issues.
- Responsible for managing, screening and hiring technical contract members for the UNIX, Mainframe and database teams.

Senior Consultant
Dell Inc.
Austin , TX
2002.01 - 2013.09
- As a Product Manager (PM) and a Lead Engineer (LE), I was responsible for getting specific third party software products finished and delivered in time to the factories for launch of the new computer models and then subsequently available to the older models. Each customer solution (software product) at Dell had a "core team" which was comprised of engineering, marketing, support, manufacturing, sales, executive, and quality representatives. The PM's role is to reach a consensus between the team members to ensure the product meets each core team members requirements without missing the launch date. The LE is responsible to make sure that product scope will be completed at launch by developing a product plan with schedule and risk mitigation and execute to that plan by coordinating development efforts, bug fixes, build releases, and issue resolution during development.
- As LE for the LatitudeON products, I had to ensure product was on schedule, feature complete, tested and validated. LatitudeON consisted of 3 distinct products: a complete software solution that ran as an application under the Windows 7 OS, an embedded USB storage device with secondary power button to support dual boot between Windows and a linux based OS, and an ARM based embedded computer contained in the Laptop case and associated HW video and keyboard switch.
- I setup and maintained duplicate build environments provided by the 3rd party developers to allow kernel and distribution builds to facilitate validation, debugging and root cause analysis of issues found during functional validation and testing. To assist with debugging startup issues, I added port writes to the kernel source to allow the use of a logic analyzer to trace early kernel boot issues.
- As LE for all Red Hat Enterprise Linux (RHEL) releases for all Dell enterprise systems, I was responsible for validating new HW with RHEL shipping and beta releases. I was the responsible engineer to determine if issues found in validation were HW or software issues and then work along side the teams to develop fixes. At times this would require the use of Logic Analyzers and advanced kernel debugging to root cause issues such has Front-side Bus protocol violations, kernel memory manager bugs for large memory servers, and Linux reboot assembly stub code.
- Conducted onsite visits of 3rd party software vendors (ISVs), evaluating their software development process, schedule creating process, issue tracking and issue resolution.
- Trained 6 engineers in India to support the sustainment of Red Hat Enterprise Linux on servers which included advanced debugging technics, use of hardware logic
analyzers, kernel debugging tools, multi-cpu debugging, kernel stack rollbacks and other debugging methods. - Developed python program to support simplified deployment of the Dell's MD3000 shared cluster storage solution. The script utilized expect module to log into remote servers and configure the shared storage.
- Supported and maintained the opensource DKMS project, to simplify the deployment and integration of new linux device drivers across many linux distributions.
- LE for InfiniBand add-in card (IBRIX).
