I am seeking a position architecting and implementing
core computing services for companies leading their industries.á My strong engineering and management skills
uniquely qualify me to help companies achieve their technical goals.

Built and led a team
of five senior architects, which designed the production service platforms for
up to 4 million paying residential subscribers of the @Home cable modem
product.á Services included mail, news,
dhcp, dns, and provisioning databases.á
Responsibly managed large
ongoing capital expenditures, meeting capacity and growth needs while staying
under budget.
Managed
re-architecture of front and back-end mail solutions to scale from 8 million
existing accounts to over 20 million in a cost-effective manner.á I managed conception and introduction of new
platforms, financial and design reviews with upper management, technical
negotiations with vendors, and coordination with project managers.á The back-end mail platform redesign saved an
estimated $5 million in capital expenditures for the planned 2002 budget.
Managed
the design and rollout of a new core provisioning database platform.á People depending on these systems included
@Home customer service call centers, most cable partnersÆ customer service
organizations, and customers using the @Home member services websites.á With a different storage solution and more
efficient volume layouts tailored to Oracle I/O patterns, performance of key
business transactions were improved by up to 13 times, while providing better
data redundancy and lower overall cost.
Restructured
Internet News (INN) service with product strategy to have the platform
producing revenue within two fiscal quarters.á
Research concluded that bandwidth for news cost much more than server
and network equipment.á As a result,
cost analysis evolved to include bandwidth projections as a product of both
architecture and regional subscriber traffic profiles, circuit requirements for
growth, and server capital needs for new deployments and ongoing field
upgrades.
Researched
and evaluated high-availability solutions as a replacement for Sun HA 1.3 and
2.0.á Presented total cost-of-ownership
report detailing expected cost reductions.á
Calculations used actual SLA metrics, actual measured time-to-respond
and time-to-recover, and empirical component failure rates for field
machines.á Considered: Veritas
Cluster Server (VCS), Integratus Universal HA, Sun HA 3.x
Created streamlined build infrastructure with content versioning managed under CVS.á This platform allowed for many ways of creating new system images: cloning disks, network-based Jumpstart, cdrom-based Jumpstart, Tivoli, or rdist over ssh.á The same mechanism was used for performing new system builds as for applying field upgrades or reimaging machines that could not be reconstructed after a disaster.
Technologies Used: Sun E4500, A3500, E420R, E220R, E450, E250, Netra T105, A1000; EMC Connectrix, Symmetrix, PowerPath, TimeFinder, PERL, Bourne shell, CVS, Extreme Networks OS

Built
all development, staging, and production systems as technical lead of the
Online Services team, which managed all consumer subscriber acquisition within
the company in addition to other revenue-generating agreements.á Responsibilities included engineering and
supporting all Online ServicesÆ computing platforms, performance tuning,
software development, and technical assistance with strategic business
development.
Engineered
a 2-tier web platform designed to handle roughly 50 million transactions per
day with 99.95% uptime.á Traffic never
met expected levels, but uptime was consistently better than the design
goal.á Planned and executed several
major migrations with no downtime.á
Migrations included physically moving equipment between data centers
while sites served over 1 million daily requests, remote in-place Solaris OS
upgrades, replacing Netscape Enterprise with Apache, and introducing Alteon
load balancers into architecture.
Software
development followed rapid prototyping and iterative refinement methods, to get
as much of the desired result as quickly as possible.á Created a dataflow engine for automatically registering domains
with InterNIC for commercial webhosting product that used a database instance
for enforcing state-model for long-standing transactions. Built a dynamic
content generation engine based upon html files and templates with a tagged
language, in early 1999 before industry had adopted a templatized
approach.á Wrote e-commerce scripts for
handling company store orders for public and private sites in 1997, using SSL
on the front-end and public key cryptography via PGP for back-end
communications.
Technologies Used: Alteon load balancers, Sun E420R, Sun A1000, Veritas VxVM, chrootÆd Apache, Oracle, chrootÆd NetGenesis NetAnalysis, chrootÆd AltaVista Search, Rsync over SSH, Samba, CVS, PERL, C, smtpd.
