Principal Software

Engineer

Core contributor to TorqueBox and Immutant

projects.

Silverpop Systems, Inc. --

Atlanta, GA (6/08-5/10)

Application Architect

Responsible for technical direction, mentoring, and training;

helped establish development best practices, including

automated testing, continuous integration, code reviews,

standard project structure and build tools.

Selected to be on first "agile pilot" team, refining the

recommendations of an independent consultant to produce the

standard agile development practices rolled out to every

engineering team.Selected to be on a skunkworks team to create Silverpop's

"inbound marketing" service, a tool used by marketers to

gauge consumer reaction to their products; parsing, storing

and rendering relevant data from Google, Bing, Yahoo,

Technorati, Twitter, Alexa, Quantcast and others. It was the

first Ruby On Rails application developed at Silverpop.

WebSingularity, Inc. --

Atlanta, GA (10/07-6/08)

Senior Engineer

Designed and built several web components for small start-up

focused on local business search, social networking, and

recommendation engines.

Bizzlr.com -- A Ruby on Rails "local search" application

deployed on the Facebook, MySpace, and Hi5 platforms, as well

as standalone. The app was designed to encapsulate the

differences between the OpenSocial and Facebook API's so that

a single deployment served all four platforms.PeoplePIM.com -- Co-designed the initial model and

architecture for a comprehensive social networking site that

included profile, contacts, messaging, calendar, local

business reviews, resource sharing, and more. Also developed

the remote API, allowing interaction with the site via both

email and SMS (OpenMarket). Built using Python and

Django.

Tandberg Television, Inc.

-- Duluth, GA (11/06-10/07)

Senior Software

Engineer

Helped design and develop Tandberg's OpenStream

Switched Digital Video solution, focusing on two areas: 1)

introducing Maven/Continuum to simplify the automated

build/release process, and 2) refactoring the EJB3 entity

relationships and the transactional services that acted on them

to minimize data access and increase performance. Using JBoss

4.0.5, Oracle 10, JDK 1.5 and Linux RHEL4.

DemandVoice, LLC --

Alpharetta, GA (8/06-11/06)

Consultant

Built SpeakFeed.net, a Ruby on Rails VoiceXML

news aggregator. Users subscribe to RSS feeds, and then call a

special number on their phone to hear their contents, using voice

or DTMF commands to navigate the stories.

CPT International, Inc. --

Marietta, GA (02/03-10/06)

Senior Technical

Advisor

Responsible for the establishment of effective web

infrastructure, development best practices, and knowledge

transfer through research, collaboration, mentoring, and

training. Development included both application and system

software, with an emphasis on the latter.

Developed an automated testing framework for

speech-enabled VoiceXML applications, capable of both

functional and stress testing. The service would compile

scripts written in a simple DSL into VoiceXML, place the

outbound calls on a clustered VoiceGenie gateway and tabulate

the results. It included a web proxy component that would

dynamically "decorate" audio files with specific DTMF tones

when requested by the application under test, enabling the

testing application to "hear" expected prompts in response to

specific inputs, e.g. DTMF, TTS, or audio. The entire

application was written in Ruby.Led the design and development of middleware to

facilitate the exchange of data with 3rd-party web sites. The

multithreaded, high-throughput service provided a simple Java

API implemented as an EJB Stateless Session Bean enabling

access to 3rd-party databases exposed via any text-based HTTP

interface, e.g. SOAP, XML-RPC, or plain HTML. Encapsulating

the transformations of the clients' requests and responses

using XSLT stylesheets, the project used many best-of-breed

open source tools including HttpClient, JTidy, and

dom4j.Developed a robust application of common Linux utilities

(ssh, rsync, at) to automate scheduled software distribution,

configuration changes and staged, reversible production

deployments to various secure networks of Linux servers.Enabled customers to test their VoiceXML applications

hosted on their own web servers, providing secure access to

the system logs generated by the VoiceGenie platform within

our internal network, requiring sophisticated parsing of the

log files to only reveal data relevant to each customer's

specific application.Developed project templates based on Maven and Struts

that enabled the quick construction of J2EE VoiceXML

applications stubbed out enough to be immediately deployable

and reasonably functional, resulting in a uniform source code

structure across all CPT projects for Struts actions, static

content, project documentation, and unit tests.Instituted a policy of "idempotent system administration"

in which system configuration was maintained under revision

control, and installation shell scripts were written

according to a convention such that any compatible Linux

server could be configured with a specific "release" of

system software. This greatly simplified the management of

the applications' system dependencies.Implemented a DMZ-style web architecture for hosting

customer voice applications. Used clustered Apache nodes as

SSL accelerators and reverse proxies to JBoss/Jetty app

server clusters, providing secure, efficient access to

various resources, including VoiceGenie VoiceXML gateways and

MySQL databases.Championed the conversion of revision control system from

Starteam to Perforce after extensive evaluation of multiple

SCM products. Led the effort to port the existing codebase

and established administrative policies and procedures

resulting in a more streamlined project lifecycle and minimal

dependence on sys-admin personnel.

Equifax, Inc. --

Alpharetta, GA (07/02-01/03)

Senior Developer

Co-led a team responsible for the reengineering

of existing mainframe processes into a more automated and

distributed web-based framework to support the delivery of

customized credit marketing data. Initial Struts/JBoss prototype

provided counts of people matching various demographic criteria

against a one percent sample of 288 million credit records in an

Oracle 9i database. User actions were captured by a "click

stream" servlet filter spawning JMS events asynchronously

persisted using EJB 2.1 CMP Entity beans.

iFleet, Inc. --

Roswell, GA (06/94-06/02)

Senior Engineer

Responsibilities included the design, development and

deployment of large-scale, distributed systems, most to serve

the special needs of inbound call centers; the evaluation of

new technologies resulting in recommendations relevant to our

customers' requirements; the establishment of standards and

best practices for development teams; the mentoring of junior

staff.

Multiple J2EE Struts MVC applications, including a means

for locating service providers closest to a particular

geocoded location, a tool for selecting roadside incident

data matching various criteria, and a framework for defining

applications in terms of services that pass XML data back and

forth via an embedded Jetty HTTP server. (09/00-06/02)Designed and developed a proprietary object-relational

persistence layer. (08/99-09/00)

Transparently mapped business objects to tables in an

Oracle RDBMS using the Java Reflection API to encapsulate

the dynamic construction and execution of the SQL

statements necessary to retrieve, save, and delete those

objects.Provided robust support for parent-child

relationships -- both aggregation and association --

including automatic cascading saves and deletes of

corresponding rows linked by direct foreign key or

intermediate association table.Combined Sun's Jini and Oracle's Advanced Queueing

libraries to form a distributed cache of replicated

business objects, synchronizing the JVM's using Jini

event notifications when the state of any cached object

changed.Featured built-in support for the automatic

management of concurrent access to the persistent objects

using an optimistic locking strategy.Data Access Resource Manager (06/97-05/99)

Co-designed a proprietary IDL and C++ framework which

simplified the development of peer-to-peer and

client-server components that created, sent and received

complex data structures comprised of STL containers.Managed stateful, concurrent access to multiple

Oracle database instances, using Rogue Wave DBTools.h++

to invoke one or more SQL stored procedures within a

single transaction corresponding to a client's

request.Efficiently spread load across distributed processes,

each with its own dynamically-configurable pool of

operating system threads and database connections.On-site consultant with Ceridian developing their

HR/Payroll application. (06/94-05/97)
