Title: Sr. Escalation Engineer; 6/2003 to 7/2013.

• Served as the principal Developer Support escalation engineer, supporting t raining, content

development, and mentoring for the Windows Phone 8 and Windows Store Application Developer

Support team. A developer that is completely stumped came to our team for developer support

assistance and solutions. Primary contributor in the public WP8 developer’s forum. Find me in

our team blog.

• Served as the principal Developer Support team escalation engineer for Windows XP Embedded

OEM developers. Served as the principal authority to escalate, take ownership and solve global-

scope XP Embedded developer problems. This role requires the ability and f lexibility to t imely

t roubleshoot systems and to debug components, user mode applications and device drivers as

needed.

• Wrote and maintained the XP Embedded Resource K i ts, the principal documentation used to

empower the customers who develop XP Embedded devices; reducing or eliminating the need for

customers to contact M icrosoft. This ultimately resulted in the reduction of the XP Embedded

support team from a team of 6 to a team of 2; (myself and a backup).

Title: Software Design Engineer; t o 11/2001 to 6/2003.

• Leveraging what was learned in componentizing Windows to create Windows XP Embedded, I

developed Component Level Testing methodologies (documentation + evangelization) to enable

operating system. This model was eventually adopted in mainstream Windows, and t ied into the

Component Based Servicing Model (CBS).

• Developed a SQL Server based system to t rack Windows Fusion file dependencies (Side by Side

D L L and EXE version control management) and COM object dependencies, and made this data

available on an internal website to facilitate development of Windows components across the

W indows organization.

• Served as Test Manager for XP Embedded Remote Boot (for Windows XP Embedded Service

Pack 1). Remote Boot allows network-boot-compliant client devices to boot off of operating

system images by copying the image into a client-side Ramdisk from a central server. Developed,

• Developed, managed, and edited all documentation related to the unique Embedded Enabling

Features found in Windows XP Embedded.

• Developed all specifications and code for Component Verifier, a tool used throughout the

W indows division to dynamically verify Windows Embedded component definitions; in particular

t he file dependency relationships between components. Contributed to the development of the

shim-based driver that was used to dynamically monitor file and registry dependencies during

component tests performed by each of the Vir tual Build Lab test teams.

T itle: Software Design Engineer; 10/1999 to 11/2000.

• Drove forth the final version of Windows 9x, named Windows Me (Millennium) Developed all

code updates to National Language Support (NLS) DOS driver maintenance, and all Windows

Me storage (IOS) technology bug fixes and enhancements, including IDE, SCSI, f loppy disk

controllers, and USB based device technology.

• Developed the required updates to the Emergency Boot Disk for Windows Me.

• Wrote a comprehensive paper that describes the Windows Me disk subsystem (IOS) in detail, so

s torage device driver developers better understand storage capabilities and limitations.

Title: Developer Support Engineer; 3/1997 to 10/1999.

• Supported, debugged and helped third party / OEM device driver developer problems,

• Architected and developed a multiple microprocessor-based (80186) emergency police/fire/911

r adio channel fault-tolerant dispatch t runking system (the Model 4048). Developed and

debugged all electronic, mechanical and software components. The Model 4048 allows up to 16

r adio dispatch operator positions (consoles) to share a pooled resource of up to 48 2-way radios

and enables operators to patch between radios or between radio and telephone lines. Developed

(C / MASM) and debugged all software associated with t raffic control. The M 4048 is still being

sold by Zetron.
