July 2022-present
Software Engineer - Engineering Leadership

On the Linux Kernel Team my primary effort is to improve their engineering discipline, and work with their tools team to help better automate their rollout and monitoring.

2015-June 2022
Principal Engineer - Office of the CTO
VMware Inc.

Principal Engineer at VMware is the highest role on the Member of Technical Staff ladder. My current role at VMware is a bit of a "swiss army knife" where I self-identify challenges across the company and help teams tackle them. As a technology generalist I have been able to jump in and help across all our Business Groups, Business Units, and IT/Security with guidance on strategy, architecture, and implementation.

I personally feel it is key for senior technical talent to remain well connected with the actual implementation details of anything they are architecting. My "side projects" continue to include several changesets & code reviews across all facets of ESXi.

I am often leveraged by VMware's Engineering Leadership, and the Mergers & Acquisitions team, to perform due diligence on acquisition targets. I have a proven track record of being able to quickly ramp up on complex products, services, and solutions, and draw conclusions about quality, usability, and performance to estimate the necessary investment for success. This piece of my role extends back to 2011 and earlier.

The Principal Engineer & Fellow community at VMware is a group of approximately 40 engineers in which I've held a leadership position since my promotion in 2013. I've worked extensively with the CTO, R&D EVPs and Fellows, along with strategic partners in HR, to broadening the community and have them be more engaged at a business and strategy level. PEs at VMware are roughly VP level individual contributors and as such have a wide purview with significant responsibility for mentoring, strategy, architecture and implementation of product, solutions, services and processes.

Principal Engineer - VMware Security, Engineering, Compliance and Response (vSECR)
VMware Inc.

I focused on extending the reach of Product Security, I became the escalation point, doing deep risk assessments and being the interface with Business Unit's General Managers and top line executive staff as the need arose. I am well connected across the BlackHat/DEFCON researcher community, and with several large penetration testing firms.

In our Open Source efforts, I was the driving force around processes for consumption, the mechanism for open sourcing our own code, and streamlining the process for making contributions to open source packages. As I stepped away from this role we created a team of 30+ to handle the Open Source work.

Sr. Staff Engineer - Product Security
VMware Inc.

Extensive work in threat modeling, risk assessment, and driving change in development processes. A wide reaching role interacting with everybody from executive staff to engineers in the trenches. Most important achievements in this role were ensuring that security concerns were addressed pre-release rather than becoming expensive to fix post-release; this entailed training Quality Engineering, Continuing Product Development, and Core Engineering to have the ability to spot and prioritize these issues appropriately. In many cases this required hands-on assessment and influence to ensure the right thing happened for a given issue.

I was a key driver for the VMware Secure Development Lifecycle (vSDL) process and its integration in to VMware's standard development processes across all VMware products and services. A distinct evolution from the prior Product Security Policy (PSP) owned by the security team originally in Continued Product Development before the formation of Platform Security in core R&D.

Sr. Staff Engineer - ESX Server/VMkernel
VMware Inc.

I worked on improvements across the VMkernel, looking for more performance and quality improvements, consolidating several per-component implementations of functonality in to a core functionality of the kernel for all components to leverage.

This was also when we evaluated a pNFS implementation, allowing me to leverage both my storage and networking background, but I was tasked with a leadership position in Product Security prior to the implementation being completed. After I left the project, the market shifted, and the work was abandoned.

Member of the Architecture Review Board. Consulting on architecture, design, and implementation across the VMkernel.

Staff Engineer - ESX Server/VMkernel
VMware Inc.

One of the leads on a team re-architecting and re-implementing the legacy storage stack in the VMkernel into what is known as the Pluggable Storage Architecture. A project that allowed EMC's PowerPath to run on ESX, and not just VMware's multipathing.

I also lead the re-design of the VMkernel multipathing module, and developed a lockless hot-path, a significant improvement over the legacy implementation.

Through the course of the vSphere 4.0 release I lead a virtual team and successfully cut the cycles per IO approximately in half when compared to the previous ESX release; most of the cycle savings came from outside of the storage code base.

October 2004-2006
Senior Software Engineer - ESX Server Storage/VMkernel
VMware Inc.

I was responsible for porting SAS (Serial-Attached-SCSI) drivers from Linux to the VMkernel. Adding support for new Fibre Channel arrays. General improvements to the entire IO stack from the virtual devices exposed to the guest OS, through the core storage stack, multipathing, the Linux emulation layer and physical drivers. During this time I first developed an asynchronous model for the LSILogic virtual device to pass IOs between the guest and the kernel.

September 2002-October 2004
Senior Clustered Storage Engineer
Addamark Technologies (aka SenSage Inc)

I worked on a filesystem-based database for the Log Management System (LMS), implementing such features as backup and restore to ensure a 100% uptime server.

Ported the LMS, a large C++ application, from Linux/x86 to Solaris/SPARC. While working with the product several performance bottlenecks were idenitified and significant improvements were implemented.


June 2000-September 2002
Senior Software Engineer
Inktomi Corporation

In the Content Network Solutions Group my key role was as an expert in UNIX kernels, software portability and performance.

I was tasked with porting Traffic Server, a high performance, transparent, caching web proxy, to VxWorks on MIPS, as well as completing the port from Solaris to Linux. The Linux port had some performance challenges so I evaluated a kernel module that "batched" syscalls and saw good results in the lab just as the 2.4 kernel improved syscall performance. Traffic Server was also where I came up with the idea of using ACK pacing to do TCP bandwidth shaping from the client-side of a connection, and worked with a small team to implement it.

June 1999-June 2000
Member of Technical Staff
Cygnus Solutions Canada Ltd.

As a GDB Engineer I was responsible for adding support for new target hardware to GDB. This entailed looking at chip specifications and making appropriate modifications and additions within the GDB source code to enable proper display and setting of registers, memory and breakpoints.

1988-June 1999
Research and Development
QNX Software Systems Ltd.

Ten years of accumulating realtime, embedded systems experience, and being part of the implementation of a POSIX compliant operating system.
