Employment History

  • UX Architect, Yahoo! Ads+Data

    Sunnyvale, CA

  • Lead UI Developer, interclick

    Boca Raton, FL

    • Lead developer and architect of the Open Segment Manager (OSM), an audience research application that allowed data analysts to harness data collected in the data warehouse, calculate lift analysis, and build targeted audiences for clients.
    • The OSM UI was written in jQuery, ExtJs, and Silverlight 4. This client interfaced a set of WCF Data Services (.NET 4.0, C#) that exposed a data tier based on Entity Framework 4 and SQL Server 2008.
    • Lead developer and architect of the Ad Trafficking System (ATS), the core web application used internally to manage nearly every facet of the business (configure publishers and advertisers, optimize campaigns, multi-faceted ad targeting, etc.).
    • ATS Version 5 was completely rewritten with .NET 3.5 (C#) with Sql Server 2008. Introduced several technologies to the company, including ASP.NET MVC, NHibernate, and javascript libraries jQuery and ExtJs. These technologies were used to help produce a maintainable and extensible n-tiered architecture for ATS.
    • Wrote a combination of jQuery and ExtJs plugins, as well as completely custom javascript to build a bleeding-edge, AJAX-driven user interface. Some client side functionality included:
      • Ad Status Indicator – ExtJs plugin that dynamically pulled the status of groups of ads as they were scrolled into view on a grid, and generating a flyout popup to provide status details.
      • Created an intuitive, accordion-based user interface for ad targeting using jQuery and ExtJs. Provided at-a-glance, natural language summaries of the mutiple facets of targeting, with the convenient ability to drill down and manipulate each facet. The natural language would update with each action, to give the user a clear summary of the changes made.
      • Sliding Panels – Completely custom jQuery plugin that provided a unique approach to workflow wizards. Each panel would initially display relevant information, and would shrink to a minimum mode as the step was completed and the next panel was revealed.
      • FollowText – Completely custom jQuery plugin that allowed convenient wireup of fields that usually had the same information; the text would dynamically input into other fields as the user typed, but would not override custom input.
    • Wrote a RESTful based service layer in ASP.NET MVC that made requests very intuitive and understandable for other developers to call and extend.
    • Derived a custom SiteMapProvider to properly accomodate MVC's departure from Web Forms. Also featured dynamic breadcrumbs that could efficiently self-build based on the stored metadata.
    • Used profiling tools and wrote unit tests to optimize performance both client side and server side in the most data-intensive portions of ATS.
    • Utilized a TDD approach to fleshing out rules and logic in the business tier.
    • Coded a generic data repository with a fluent interface for chaining various lazy-loading scenarios when constructing nHibernate queries.
    • Managed the UI/Logic team to complete the initial ATS project, as well as maintain and extend in subsequent iterations.
    • Wrote "best practice" documents that guided developers with coding standards and methodologies when using various aspects of the architecture: constructing efficient nHibernate queries, writing unobtrusive JavaScript, and invoking/extending the service API in a RESTful manner.
  • Senior Developer, WhoLived LLC.

    • Created a framework to dynamically load ASP.NET User Controls on the fly from the client, and simultaneously register and execute associated JavaScript resources so that the controlling page could participate in events that take place in those resources.
    • Created several ASP.NET custom controls, including some to extend the databinding capabilities of ObjectDataSource.
    • Worked with Virtual Earth and Google Maps APIs to plot location-based data. Created JavaScript timelines to chronicle time-based data.
    • Created C# based server media processor to process user-uploaded documents, transcode videos, and crop/resize images with ImageMagick, GDI+, and FFmpeg.
