    Internet Deployed Application Architect

    United States - Last active: 01/14/2011 - Tests: 7 - Portfolio: 2

    Developing for the Internet is a unique paradigm because it ties in with so many aspects of a business. I've had the good fortune to work with small companies and on large scale applications so I am familiar with the dynamics of identifying and meeting stakeholders' needs. I have adopted a framework for delivering that includes a large effort upfront to ensure understanding of the business needs and the stakeholders goals so that time will not be wasted refactoring too many changes later on. This includes a process of approving mock-ups and story boards which is the most effective at clarifying specifications. I implement principals of high availability (over 20k useres per month), service oriented architectures (C# web services returning XML or JSON), object oriented programming (discreet interface, business logic, and data access layers), and new methods of developing web interfaces with Javascript libraries like Jquery. Right now I build sites that provide a high level of interactivity using XMLHTTPRequests to consume my C# built web services delivered in JSON, usually pulling data from MS SQL Server. I have implemented the following features on various websites: * Credit Card Gateway * Multi-threaded web crawler / screen scraper * RSS Feed Agrigator * File Upload with AJAX progress bar * Image manipulation, resizeing, cropping * Storing data with Rijndael encryption * Web services with SalesForce * Interactive Charts / Plots with JSON data * Search and ranking algorithim * Data transformation, parsing, linking
