Livermore, CA, US

Contributed to the design and development on a system for collecting, storing, and analyzing semantic graph data. Designed a graph model API and a mechanism for dynamically generating JPA mappings from ontology definitions. Designed a rules-based pattern matching monitor for searching for subgraph patterns during data ingest. Implemented an entity.

Livermore, CA, US

Designed and developed web and Swing IT applications and web services for the National Ignition Facility (NIF). Implemented the JAAS-based authentication and authorization framework, and SSO solution, used by all NIF IT applications. This security framework was later adopted by many projects outside of NIF. Was involved in the design of the majority of the.

Design and development of Intraspect’s B2B collaboration product. Implemented distributed search capability, redesigned the security module to integrate AD and any third-party authentication, improved integration with the Verity index service (Java & C++), and helped develop & maintain nearly every aspect of the product.
