Next-generation Anti-Spam Web App manages both human-specified and real-time, proprietary, AI-model-generated email server (domain) reputations. This is a 100% AJAX Web Application built on top of an extremely lightweight, reusable, Model-View-Controller (MVC) architecture framework.
Both the Anti-Spam App, and the MVC framework upon which it's built, were hand-coded from zero to completion. A built-in system for debug, testing, and for developers to learn what's going on under the hood is included. The framework is a template for rapid development and deployment of future tools, and its structure and extensive documentation teaches state-of-the-art MVC collaboration and software design practices.
(The MVC methodology framework was not part of the original project specifications: It was my idea to push things ever further forward at Yahoo! - enthusiastically approved and supported by management!)
ANTI-SPAM BACKGROUND: When anyone, anywhere in the world, clicks on 'Report as Spam' or 'Not Spam' in Yahoo! Mail, Yahoo! Messenger, etc... that information (along with similar info from several other sources) goes into a huge, distributed database. This immense database tracks information like the 'spammer/hacker reputation' of the sender and the server (domain) where the email originated, all minute by minute, 24/7, world-wide, in real time.
The tools I developed for the Mail/Anti-Spam team (one of which is highlighted here) allow Engineers, Managers, and the Customer Care team (the folks that answer the phones at Yahoo!) to access that wealth of information in a simple, intuitive, secure and expedient manner. This allows Customer Care to tell you just what's happening when you call in, Engineers to respond quickly to new spam/hacker/phishing threats as they arise, and Managers to analyze spam trends as well as effectiveness of Yahoo! Anti-Spam technologies and protocols.
Features highlighted here are now standard (eg, MVC Design Methodology, Web App Framework, ORM, Smart Forms, live manipulation/searching of Database data in-place/without page reload). Obviously, the state-of-the-art is a moving target. Since these were novel ideas at the time, however, I believe this demonstrates the perspicacity I'd bring to tech decisions for your projects.
