Ranbir Chawla — As Director of Web Apps Development Ranbir Chawla has overseen the design and development of the current and past architecture for our personalized Web engine, as well as our core usage tracking system, for the last three years, since version 1.0. This architecture has allowed EarthLink to scale the current portal system by a factor of three times without increasing the capital expenditure for hardware or software, helping to further drive up margins on incremental revenue. The system also allows for complete partner cobranding and customization, which further drives member acquisition. His team has also driven the PSP systems integration process with IT and MIS, allowing the personalized Web engine to tie into the Radius authentication systems and our CIS for seamless login and provisioning of all of our personalized content.

Ranbir began his career at EarthLink in November of 1996 as a manager of Web hosting products, with the goal of building a state-of-the-art Web hosting service. In January of 1997, he transferred to the fledgling Member Services division and took on of the construction of EarthLink's Personal Start Page. The current extends the core architecture with the use of XML and XSL style sheets, and a complete rewrite in C++ of the core display code. The goal here is a much more flexible system that can scale by a factor of 2 without additional hardware, and a state-of-the-art user interface with DHTML, etc.

In mid 1998, Ranbir created a Data Services group within Web Development to create a more scalable and accurate tracking system, complete with a real data warehouse of user activity/traffic patterns, user retention relationships, and partner tracking information. The last phase of this system was implemented December 1999, completing the project on time and in budget.

Before joining EarthLink, Ranbir was the founder of a successful consulting firm in Denver, Colorado, specializing in Internet E-Commerce, large-scale systems integration projects, and network technology applications. Prior to that he was a securities trader with a variety of top tier firms, specializing in NASDAQ securities and Derivatives.
