* Project lead for multi-year research and transition program to integrate Lymba's NLP extraction and semantic calculus for structured and unstructured alignment to third-party ontology for IC. { C++/Java/Python, Hadoop/UIMA/RDF } - Developed ontology-mapping software to map internal semantic representation to third-party ontology for output as RDF XML and N-Triple formats. - Integrated grid-based distributions and developed JNI APIs deployment in Hadoop. - Converted all NLP tools into UIMA annotators. Developed UIMA type system for NLP components.* Lead Software Engineer for Question Answering (PowerAnswer). { C/C++ } - Engineer for question processing module for SMS-input. - Integrated third-party RDF and document retrieval systems. - Implemented RDF-based answer type detection component.* Lead Engineer for web-based Electronic Medical Records system for mental health therapists. { Groovy/Grails/Java, Hibernate/node.js } - Designed and led development of automated diagnosis recommendation system. - Implemented social networking capabilities including user recommendations based on system activity, user communications and profile components. - Integrated with third-party service providers (financial and claims) and developers.* Developed data-based customization extension for semantic extraction tool. Designed and implemented a custom grammar for relation argument composition and mapping to third-party target relations. { C++ }* Developed in-house NLP tools. { Java/C++ }* Refined document classification algorithm (naïve bayes and maximum entropy) for a proposal clustering and reviewer matching system. { Java }* Implemented data-driven methods for semantic relation candidate argument extraction. { C++/Python }* Co-wrote successful government and private contract proposals.* Developed components for grid-based distribution of NLP processing tools.* Delivered project and product presentations for internal use, for customers, and at conferences.

* Implemented and shared in design of PowerAnswer, a scalable, modular end-to-end Question Answering system. Designed system components, implemented question processing & answer type detection, keyword selection & information retrieval, answer processing components. { C++/Java/lex/yacc } - Led design and implementation of extensions to PowerAnswer to enable multimedia and multilingual question answering.* Co-authored three successfully awarded research contracts.* Lead SE for Question Answering group implementing tasks for above program. Directed a small group of 4-7 engineers and researchers. { C++/Java } - Development responsibilities: developed question processing modules; developed components for analyzing ASR for detecting semantic relations within multimedia; implemented methods for automatically building text search indexes from arbitrary structured databases; developed multilingual QA module. - Program management responsibilities: directed small team of (<=7) software engineers; worked with research scientists on Program tasks; integrated projects from LCC & other Program contractors; prepared and performed on-site and workshop meeting presentations and demonstrations, delivered status reports, managed visiting analyst workshops testing in-progress software, wrote final delivery documentation.* Developed improvements for a number of NLP tools and tasks such as tokenization, part-of-speech tagging, syntactic parsing, word sense disambiguation, named-entity recognition, lexical chaining, semantic parsing, text retrieval, text inference. { C++/Java }* Developed specific improvements in advance for, participated in and co-wrote workshop papers for a number of government-sponsored evaluation challenges. - TREC 2005, 2006, 2007 NIST question answering challenges – LCC's PowerAnswer system was top performer each year - TRECVID 2005 NIST video retrieval challenge - QA @ CLEF 2006, 2007 multilingual question answering challenges

* Developed specific improvements in advance for, participated in and co-wrote workshop papers for a number of government-sponsored evaluation challenges. { C++ } - TREC 2003, 2004 NIST question answering challenges – LCC's PowerAnswer system was top performer each year* Researched and implemented a knowledge base of linguistic axioms for use in a text inference engine (COGEX). Inspected questions and candidate answers returned to detect patterns in the linguistic axioms required to provide a valid proof by contradiction. { C } - Designed and developed a module to dynamically build linguistic axioms from rules expressed in a custom grammar for the parse trees of the candidate answers and the question. * Designed and implemented an agent-based system for question answering on the web. The system identified and tracked user interests, discovered related and relevant topic spaces and performed automated searching. { Java }* Proactively set-up and designed internal engineering & research wiki that resulted in improved project documentation, resource management and shared knowledge. { PHP }* Performed recruiting and interviewing tasks as needed, including travel to career fairs and on-site interviews.

* Developer for Internet Safari, a children's secure internet browser constructed from the ground up by a small team. { C++ } - Designed and developed HTML rendering components and user interface modules.* Wrote support applications for company including web applications, database support and analysis applications and operating system applications. { Perl }

* Web design, coding of corporate websites and server-side applications including Java and Javascript components. * Performed ISP administration tasks including setup and management of hosted domains.
