PROFESSIONAL EXPERIENCE

March, 2009, to date

Independent Consultant (through ArdenTex, Inc.)

SDI Health, LLC., 220 West Germantown Pike, Plymouth Meeting, PA 19462

SDI Health provides health care data solutions to various companies in the health care business space. SDI processes data from a variety of sources, produces master databases of patient, pharmacy, practitioner, payer, and product data. With that master data in place, SDI can then scrub client-supplied data, analyze health care trends, and perform a variety of other data-related tasks.

My duties, as an independent consultant for SDI, include:

• Tuning and reverse-engineering existing legacy systems
• Designing and implementing new data normalization software
• Participating in the rearchitecture of the internal data warehouse
• Providing software technical advice and direction

The data warehouse rearchitecture effort requires consuming, normalizing, mastering and maintaining millions of rows of health care-related data records from disparate sources. We chose to write the data handling framework using Microsoft SQL Server Integration Services (SSIS), and the effort has required that we write custom SSIS components, in addition to using the stock SSIS ETL transforms.

February, 2008, to March, 2009

Senior Software Engineer

Invite Media, Inc., 1716 Chestnut Street, Suite 4, Philadelphia, PA 19103

Invite Media builds technology and provides network services to facilitate Internet optimized advertising. As one of the senior developers, I was a member of a small team that was responsible for specification, design, and implementation of large-scale, real-time advertising technology. As of March, 2009, Invite Media's systems were providing optimized advertising solutions to a number of customers.

The system was written primarily in Python, with some components in Java. It consisted of various Internet-visible servers and several back-end databases, and it is designed to scale to very large numbers of connections and transactions.

Technologies and techniques used included:

• Amazon's Elastic Cloud Computing (EC2) services
• Amazon's Simple Storage Service (S3)
• The Hadoop map/reduce framework
• The Twisted Python framework
• The RabbitMQ messaging framework
• PostgreSQL
• Django
• SQLAlchemy

These, and other, technologies were tied together with proprietary ad-serving software that provided highly optimized ad delivery.

June, 1999, to February, 2008

Enterprise Architect / Senior Developer

FullTilt Solutions, Inc., 1400 Liberty Ridge Drive, Suite 100, Wayne, PA 19087

I was one of a handful of senior-level developers of the FullTilt Perfect Product Suite product information management tool. We developed, from scratch, a business-to-business ecommerce product that streamlines the management of product data. The product embodies a work flow process that enables a company to process, classify, attribute, search, maintain, and deploy large volumes of product data without requiring armies of data entry personnel. The product's server-side software is written entirely in Java, allowing it to be deployed on a variety of different platforms. Perfect Product Suite's user interfaces consist of browser-based HTML screens that interact with server-side Java servlets.

Perfect Product Suite can import product data in a variety of formats, including spreadsheet data and Perfect Product Suite's XML format. Once the data has been normalized and attributed, Perfect Product Suite stores the data in a relational database, where it is organized according a powerful, proprietary data model.

Perfect Product Suite performs all database access solely via JDBC; consequently, it will run against any robust, full-featured relational database that supports JDBC access. We explicitly support and test against Oracle, IBM's DB2 and Microsoft's SQL Server.

Perfect Product Suite is patented; I am listed as a co-inventor.

As a senior developer, my duties included architecture, design, development, and, occasionally, sales support. I have worked on every component of Perfect Product Suite; among these components are:

• the UIs and servlets
• the database API, which maps the relational database view to an object-oriented one
• the utility library
• the proprietary back-end Import Manager process that automatically classifies and process imported product data
• the XML parsing engine

In March, 2007, I assumed the position of Enterprise Architect, putting me in charge of the overall architectural direction of the product.

The members of our team were located all across the country, and many of us (including me) worked from home offices. Producing a quality product required us to master the challenges of collaborating across large distances and several time zones.

April, 1997 to June, 1999

Senior Architect / Senior Software Developer

PLATINUM technology International, inc. (acquired by Computer Associates International in 1999), Three Valley Square, 512 Township Line Road, Suite 300, Blue Bell, PA 19422

Prior to its acquisition by Computer Associates, PLATINUM was a large software company that focuses on corporate enterprise management software. My group developed and maintained the PLATINUM Open Enterprise Management System (POEMS), a unified infrastructure into which all PLATINUM products were integrating, to provide seamless operation, administration, and look-and-feel across the PLATINUM product line.

In April, 1998, I was promoted to the position of architect, with responsibility for the "back-end" (non-GUI) components of the POEMS infrastructure. Along with the front-end architect, my duties included:

• Reviewing designs to ensure consistency with existing POEMS architecture, future POEMS and PLATINUM product directions, and current development methods.
• Keeping abreast of architectural changes to POEMS software.
• Staying current with competing products and with industry trends.
• Designing components that reach across the internal POEMS teams.
• Participating in management decisions for current and future software releases.
• Analyzing requirements for internal POEMS consumers and external customers, and to help design and plan POEMS/product integration.
• Serving as internal senior consultant for other software developers.
• Engaging in short-term research and prototyping. In this capacity, I built a working Java prototype of the POEMS back-end IPC services. This prototype bcame the basis for our internal Java IPC solution.
• Assisting in software development and production (e.g., filling in on development teams when necessary).
• Participating in PLATINUM-wide architecture meetings.

Prior to assuming the architect role, I was a senior member of one of the internal POEMS development teams. On that team, my duties included:

• Responsibility for maintaining, enhancing, and continued design of the underlying POEMS communications infrastructure.
• Acting as co-team leader for my team, which entails planning projects and coordinating development among other team members.
• Broader design, across all of back-end POEMS services.
• Meeting with other PLATINUM labs to help them understand how to integrate with our technology.

Shortly after PLATINUM was acquired by Computer Associates, I left the company to join FullTilt.

• Building a C++ lex- and yacc-driven command shell for a proprietary full-text database system.
• Designing and partially implementing an NFS proxy to permit tunneling NFS traffic safely from behind the corporate firewall to machines in the firewall's DMZ. (See document entitled Notes on a Proxy for Securely Tunnelling NFS through Firewalls for details.)
• Investigating new technologies.
• Evaluating full-text database retrieval software.
• Informally training other employees on UNIX and the Internet.
• Filling in for and training our UNIX system administrators.
