Work Experience

  • Staff Software Engineer, Google Inc. 2003 -
    • Product Search (Froogle)
    • Google Checkout: as the first engineer in the project, conceived, designed, and form the team. Google Checkout launched in June 2006.
    • Google Billing and payments: responsible for the day-to-day of the billing of AdWords revenue. Automatized the system, significantly cutting down the time that the process took.
  • Research Assistant, Stanford University 1996 - 2002
    Advisor: Professor Hector Garcia-Molina
    • Led the design and prototype implementation of the Stanford Archival Repositories Protocol.
    • Researched and evaluated the complexity of algorithms for efficient handling of query subscription in a multicast environment.
    • Co-designed SDLIP, the Simple Digital Library Interoperation Protocol.
    • Investigated algorithms for fast reconciliation of database replicas with independent updates.
  • Research Intern, Xerox PARC Summer 1996
    Mentors: Dr. Eric A. Bier and Dr. Bay-Wei Chang
    • Led the design of the Meteor Shower Architecture. An architecture that allows responsive interaction for a large web application.
    • Developed WebWriter II Editor, a direct manipulation HTML editor that runs in a web browser, as a test of the flexibility and efficiency of the Meteor Shower Architecture.
  • Research Assistant, Stanford University 1995 - 1996
    Advisor: Dr. Andreas Paepcke
    • Developed a complex translator between the Dialog database and the Stanford Digital Library protocol. This translator offered unlimited virtual sessions by multiplexing over a small set of Dialog accounts.

Dissertation: Digital Library Repositories

Current libraries use an assortment of uncoordinated and unreliable techniques for storing and managing their information. Some of their collections are in paper form, which can decay and can be lost. Digital information is stored in file systems, Web sites, database systems, and information retrieval (IR) systems. Typically the systems are good for some functions but not others. For example, a system may have good text search capabilities, but not reliable storage. Often information is stored in legacy systems that are hard to integrate with modern ones. Across these diverse systems, information is stored in various incompatible formats, and accessed using different command languages. My goal is to design and build a modern Digital Library Repository (DLR). Such a repository stores and manages the digital objects that constitute the library. My goal is not to replace existing systems (e.g., database systems, IR systems), but rather to allow existing and future systems to work together in managing and preserving an interrelated collection of digital objects (and their versions) in the simplest and most dependable way. Like any modern information repository, a DLR must be secure, reliable, and scalable. In addition, a DLR has the following combined key requirements that distinguish it from other repositories. First, digital objects (e.g., documents, technical reports, movies) must be preserved indefinitely, as technologies, file formats, and organizations evolve. Second, DLRs will be formed by a confederation of independent organizations. Third, published digital objects have a historical nature, so changes should not be done in-place; instead, they should be recorded in versions.
