How would you describe your time at classmates online?
Jack of all trades in a well established yet small company (~200 employees). I feel this is
an excellent opportunity for me, as I experince all aspects of networking, from complex network architecture projects to building cat 5 cables by hand. Our network team is very small (2 people) so I get to wear many hats. I am responsible for IT security, network design and implementation, cable plant, and even system administration tasks (Linux, Solaris, Windows, etc).... 
Network Engineer
How would you describe your time at T-Mobile?
Contractor on site at T-Mobile as an implementation and planning network engineer. In this position I was responsible for documentation, planning and implementation of all core network upgrade, installation and maintenance activities.
Here I regularly wrote implementation and maintenance documentation to guide our Tier 2 staff through technical processes. I was also responsible for evaluating and improving design proposals handed down from the network architecture group. Regulary worked with Cisco 7600, 6500, 4900
routers/switches. Also had significant experience with Cisco VPN hardware, both 3000 series
concentrators and ASA series security devices....
Senior Network Engineer
How would you describe your time at Amazon.com?
I'm proud to have worked at the world's largest online retailer. As a senior engineer in
the Network Architecture team, I was exposed to the cutting edge of computer networking.
Notable experiences include:
Lead architect for network monitoring and analysis projects
I wrote much of the software we used to monitor our global network. Created a network database
to track all equipment and provide a source of record for other monitoring tools. Regularly
wrote custom software to integrate existing monitoring software. Wrote graphing software to
display data about network metrics gathered by a collection agent I wrote. The agent was modular
to allow for any arbitrary collection module to be integrated, and I wrote the SNMP and automated
login module for the collector.
Actively involved in data center network designs
I was involved in creating standards and repeatable designs for rapid data center deployment.
Contributions to this project included IP allocation standards, device configuration standardization,
automation of monitoring for newly deployed equiment, and procedural documentation for datacenter
technicians who deployed new equipment.
Lead architect for all remote site VPN/WAN networks
Soley responsible for network design for all remote sites including remote offices, distribution
centers and customer service centers. Managed timelines and resources across multiple groups to
ensure timelines were met for our extremely aggressive schedule. Deployed over 50 remote sites in
one calendar year, which would not have been feasible without standardization I introduced.
Responsible for subnet assignment and management
I was solely responsible for all IP space at Amazon.com, and wrote software to manage both current
subnets and new allocations. The application would also monitor which subnets were found in router
forwarding tables and would display the information accordingly.
Administration of network monitoring servers (Unix and Windows)
I was our system administrator for our monitoring servers. Most servers were Linux or Solaris, but
a few were regretably running Windows.
At Amazon.com I was exposed to nearly all models of Cisco network equipment. I regularly evaluated yet-to-be-released equipment from various vendors, and provided buying descision guidance. I had daily interaction with load balancers, routers, switches, and firewalls....
Senior Network Engineer
How would you describe your time at Seven Networks?
At SEVEN Networks, I was the lead architect for all network designs and deployments. Duties included
creating and upgrading routing policy (BGP, OSPF), configuration of new network devices, documentation of
network architecture, VPN design and implementation, and network monitoring.
I wrote custom Perl scripts to monitor devices on our network, integrating them into software such as
HP OpenView and Big Brother. I worked with mainly Cisco equipment including Catalyst series switches,
routers (2600 - 7500 series), Arrowpoint content switches (css-11000 series), PIX firewalls, and VPN
devices. I was in charge of our network monitoring architecture and implemented HP OpenView, RRDTool
for traffic graphing, and third party monitoring from external sources....
Senior Network Engineer
How would you describe your time at Amazon.com?
When I first started at Amazon.com, I was an engineer in the Network Tools and Analysis team. I started as
a Network Engineer I, and quickly (within three months of being hired) moved up to Network Engineer II with
project lead responsibilities.I worked with HP OpenView, MicroMuse Netcool, all Cisco software suites, and
freeware tools such as MRTG and RRDTool. I was project lead for all of our in house (Perl) monitoring
software applications including traffic graphing, network latency reports, alarm generation for on call
engineers, WAN circuit monitoring, and even uptime monitoring of our monitoring software. After 6 months
of employment, I was given the authority to prioritize my projects without intervention from management. I
was also given the freedom to create and prioritize new projects at my discrecion. I was also promoted to
project lead and delegated work load for my projects to our team of network tools engineers.I gained much
experience with Cisco products including all series of routers, switches, WAN switches (IGX/BPX), PIX
firewalls, LocalDirectors and Distributed Directors. I worked very closely with Cisco product
representatives, software engineers, development engineers and network engineers to drive their development
of their software and hardware to meet our requirements and unique needs. I participated in our on-call
rotation, providing tier 2 support of our global network including all network related hardware and
software. I was later promoted to the tier 3 support oncall team. This was an honor for me as all other
engineers in this group were senior network architects.One of the greatest skills I learned at Amazon was
the ability troubleshoot any networking related problem, many which had never previously been discovered in
the technical community. As a result of my oncall experiences, I voulunteered for the responsiblity of
driving vendor product development and bug fixes. Many times I was required to engineer work arounds when
the vendor could not provide a satisfactory solution or time to resolution. I also furthered my experience
with OSPF and BGP routing protocols....
