  • Senior Software Engineer

    2005 - PRESENT
    BA Insight
    • Helped develop Longitude Search, which extends the search capabilities of Microsoft SharePoint (quick document preview, search refinements, save search queries and alert about new search results, etc.).
    • Developed a document preview UI for Longitude Search from scratch.
    • Contributed to the development of BA Insight Content Connectivity, which allows indexing of data from various content sources (EMC Documentum, Microsoft Exchange, SalesForce, HP Trim, LiveLink, eRoom, etc.) to a SharePoint Search, as well as transforming/enriching that data (support of security, including multilevel security, data transformation using client scripts, etc.). The product was designed to work well with a large volume of data (millions of documents).
    • Helped build Smart Analytics (similar to Google Analytics).
    • Contributed to the creation of Auto Classifier, which extends the Managed Metadata feature available in SharePoint and allows users to fine-tune the relevance of a taxonomy term for a given document via custom full-text queries and custom scripts, as well as visually test the results of the classification.

  • Smart Previews

    Smart Previews boost productivity by helping users quickly find what they seek, explore inside documents and attachments, identify content to re-use, and automatically assemble it into new documents.

  • BA Insight Indexing Connectors

    • Provides secure, high-performance crawling and indexing. Connects to a wide variety of systems.
    • Manages sophisticated security scenarios.
    • Maps security entitlements with source systems into the search process.
    • Ensures that results are trimmed to expose only content the user has access to.

  • Smart Analytics

    BA Insight Smart Analytics provides valuable data to make intelligent decisions about your intranet (similar to Google Analytics). Smart Analytics can help you turn user insights into action to improve your search center’s performance.

  • Auto Classifier

    Classification software that uses text analytics to create metadata, leveraging SharePoint’s Managed Metadata Service (MMS).

    My contribution here is the Scripting feature which allows fine-tuning of scoring rules via custom scripts written in C# or VB.NET.
