billing declines which increased overall capture by 10%. Wrote the account upgrade/settings code used by all 4 million hosted web sites.

Migrated 50,000 paid accounts from an older billing system to a new one. Integrated with several 3rd party API's for real-time credit card

processing (AuthorizeNet, CyberSource, and ProPay), registered domain administration (Register.com), billing systems (Extent, EclipseNet),

and auction software (CommerceFlow).

Skills Applied: Perl, Oracle, Apache/ModPerl, XML/XSD, Linux, Engineering for System Scalability, Accounting/Finance Engineering

Project Highlights

TSANet Inc. Marketing and Member websites, Eli Kirk: 2008 - 2009

TSANet ("Technical Support Alliance Network") is a collaboration network formed by many of the largest technology companies including:

Microsoft, Oracle, HP, EMC, Red Hat, and Symantec. It facilitates easier resolution of multi-vendor technical support cases. They had been

using a legacy system for several years, that was inflexible and didn't allow them to change and scale their network. We were contracted to re-

build the system from the ground up, make it more flexible and efficient, provide a clean new look and use the latest Web 2.0 interface

technologies. One of the biggest challenges this project presented was a high level of data complexity and access permissions. For example, one

participant can only see another participant's information if their member subscription and per-user settings allow it. The new system allows

TSANet to run their system on less hardware, have faster performance, and be able to easily adapt it to serve new markets and industries.

ODYC Hosting System, Self-Employed: 2004 - 2006

After a previous hosting business, LiquidOrange.com failed in the end of 2003, my partner and I set out to rebuild the platform from scratch to

make it more scalable and robust. We were tried to use some of the old code from LiquidOrange.com, but in the end started completely fresh. I

laid out a completely new hosting solution which included a reseller model, and a billing solution, site builder, e-commerce application, and

hosting administration system. The billing solution was designed to allow strategic partners, or ourselves to easily monetize the hosting accounts

and run all types of promotional offers online or offline. The site builder included a powerful and flexible site template system, an image

manager, and advanced web-entities to run photo albums or other path based processes. The site builder also included a multi-lingual engine to

allow whole-site language switching. The e-commerce application included advanced product sub-categorization and inventory management,

international standard tax and shipping algorithms and a modular checkout system. Several times through the project we outsources graphics

work to independent designers who I was responsible to manage. My partner Steve provided funding and business knowledge, but I was the

only developer that created these systems, working self-motivated for 2 years on this project.

IDBS / Synoma Programming Environment, Inetz Media Group: 1999 - 2000

This was a programming language for web systems that greatly increased the speed of development for Inetz projects. I created the language for

myself and my own development efficiency and used it for several months before the owners became aware of it. Originally, I named it IDBS

for "Inetz DataBase System". The language is HTML embedded with external object definition files which greatly streamline SQL queries and

web object pagination. A database layer allows developers to have full access in a simplistic database-agnostic manner. The database access and

query methods were simple enough to empower HTML coders to develop feature-rich dynamic shopping carts, intranets, and web portals.

Inetz's low-end HTML people became mid-level application developers, and soon the majority of new Inetz projects were coded in IDBS. In Jan

2000 we began looking into building IDBS into it's own standalone marketable product. The new product "Synoma" was to compete in the same

space as Cold Fusion. Investors were secured and we selected programming teams in Syria where I would also move during the development.

The project was to be fast-tracked and aimed for an IPO mid-2001. In May 2000 however, after much research we decided that we were too late

in the game to compete, and abandoned these business plans. Inetz continued to use IDBS for the rest of the time that I worked there.

Billing and Recapture System, NetZero (Web Services): 2002 - 2004

At the end of 2001 NetZero (Web Services) realized that their current billing system, Extent RBS, was not going to scale and decided to

purchase Sandlot EclipseNet and migrate their customers. I had been the primary engineer over billing and was tasked with the project. During

March and April I re-wrote the billing libraries into a billing-system-universal API so that we would be able to have all other code be

unaffected by the changeover. By switching to EclipseNet we would have to switch from "Anniversary-Day" billing to "First-of-Month" billing

which meant that all our 50000+ customers needed prorated billing for July. Also, missing in EclipseNet was a system to auto-run billing each

month, so I had to create a billing daemon and check system to see each of our customers were billed properly.

Once the billing system was transitioned, we began to look at retention and recapture. Out of the gates we only tried our customers credit cards

once per month around the 6th of the month. We thought up many ideas for retrying the customers credit cards, and eventually I put together the

following system: each decline is attempted up to 9 tries over 3 months (when the transaction fees outweigh the amount captured);

communications are sent to people telling them their credit cards are expiring, then notifying them of declines on retry rounds; each decline

round increased the disabled-level of the site until after the third try when all site activity was suspended; customers can login online to self-

clear payments; card processing rounds were placed on dates or greatest opportunity when charges are most-likely to clear. Before the recapture

system 75% of our customers cleared and 25% declined. After the new recapture system was implemented and tuned, we cleared %89, leaving

only 11% declined.
