Ported and maintained terminal emulation software on first-generation PCs for Univac systems.

Adapted data clustering and sequence mining techniques from bio-informatics to information retrieval problems. The problems included offensive web-search filtering techniques, spam filtering, online-behavioral analysis. Additional applications to server failure-mode analysis were explored. Simulated the interactions between content access patterns, internetwork topologies, and server loads to determine optimal network architecture and hardware requirements for global content distribution systems. Completed a technology survey of object-oriented forward-chaining expert systems, including theoretical work on the difficulties in extending traditional models to object-oriented frameworks. Refined internal software design and development patterns through the application of functional programming principles and category theory to object-oriented development. Debugged numerous problems with development platform and in-house framework internals based upon broad knowledge of networking, operating system and virtual machine architectures.

Founding director of corporation. Developed business plans and the technology to implement them. Negotiated content deals for website products. Assumed architectural responsibility and technical leadership for 10-year old ETL and content management systems and produced roadmap documents for the renovation of vital infrastructure. Supervised the implementation of the roadmap systems. Evangelized the use of industry standard ETL tools (AbInitio) and web service architecture (SOA) throughout the web-publishing organization. Provided technical oversight and evaluation of pilot projects for all new technologies in web publishing. Designed and reviewed key components of the AOL Video infrastructure roll-out, providing technical direction for all metadata and content management development connected with the video initiative. Coordinated metadata definition, responsibility and ownership among a globally distributed development team. Development of ontology standards and their consistent usage patterns across AOL's content products. Designed and reviewed system architectures for the capture and maintenance of controlled metadata vocabularies. Completed several project transitions between different global branches of a multi-national corporation. Project transition included documentation development, preparation of training materials, and mentoring in design and development processes.
