Work Experience

Softaware Engineer, ITA Software, Cambridge, MA.

• Please inquire for details.

Senior Software Engineer, Centive, Bedford, MA.

• Helped develop and maintain the Centive Incentive Management software, based on J2EE, WebLogic, WebSphere, Oracle, etc. Please inquire for further details.

Architect, eRUNWAY, Westborough, MA.

• Designed a J2EE-based suite of applications for use in retail stores. Led the development of some of the applications. (WebSphere, SQL Server, MQ-Series, EJB, Struts, JSP, JNI, C++, etc.)
• Created architectural design and handled technical issues for a major client project in product catalog administration. (Weblogic, EJB, SOAP, Applets, Swing, Struts, JSP, etc.)
• Wrote implementation of SOAP in Java that provided an RMI-style interface on the client-side and the server-side

TimeŘ, Perot Systems, Cambridge, MA.

• Developed architectural design for an Indian ASP Digital Marketplace client, serving as Lead Engineer in December 2000, based on WebLogic and EJB.
• Developed architectural roadmap for an EBPP client, serving as Lead Engineer from August 2000 to November 2000. Evaluated WebMethods, WebLogic Collaborate, and other integration tools.
• Improved Oracle search performance for an ASP service that performs web-site indexing. Wrote SQL stored procedure for performance-critical search section.
• Developed the MarketCAP platform for Time0's Digital Marketplace systems, serving as Lead Engineer of this team from April 1998 to May 2000. This involved Java, threading, RMI, EJB and ActiveWorks messaging middleware.
• Assisted in the design and development of an electronic commerce system over ActiveWorks middleware. Integrated the middleware into Java, C and Perl, and with third-party software. Helped develop a client system over this platform, serving as the troubleshooter towards the release.
• Wrote a middleware-enabled profiling component to hold user data.
• Evaluated several cryptographic packages and systems for use on the Web and over the middleware.
• Designed and developed a two-tier rendering engine based on SGML/XML.

Nets, Inc. (Cambridge, MA), and its subsidiary Industry.Net (Pittsburgh, PA).

• Designed, coded and deployed initial Industry.Net web-site in Aug 1994 using Perl5 and NCSA httpd.
• Designed Oracle database schemas to store catalogs and integrated into CGI programs using ProC and Oraperl.
• Customized two httpd servers (NCSA and plexus) to embed Oraperl and persistent processes to obtain better Web response-time.
• Developed initial commerce system at Industry.Net using Oraperl based upon consultation with business clients. Designed product-data storage schemas to reflect business practices.
• Designed a flexible attribute-value based object storage schema in Oracle for storing heterogeneous business information.
• Designed and implemented a light-weight, high-performance logging system based upon UDP packets and a multi-threaded buffering system using shared memory and semaphores.
• Designed and implemented under contract to NIST/MEP a forum for anonymous, secure negotiations based upon Notes/Domino using Lotus Script and Notes agents. Also designed new cryptographic protocols for triple-blind negotiations.
• Designed and implemented a generalized templating system for displaying arbitrary legacy data in diverse output formats.
• Headed a project team that developed a prototype system for automated scanning, OCRing, indexing and Web-publishing of bulk paper-documents. Used Adobe Capture, ftp, Excite text-search engine, Perl and cron.
• Designed and implemented a high-speed user-interface in multi-threaded Java, FastCGI and Oraperl to permit untrained temps to search Industry.Net's database of 300,000 companies. Achieved 100ms response-time, permitting incremental querying of the database upon each keystroke by the user.
• Participated in the design of a high-performance commerce architecture based upon messaging middleware.
• Participated in the evaluation of many software companies and products: Krakatoa, OpenMarket, IBM WOM, Web Objects, Documentum, Trilogy, Aptex Convectis, Claret, Retrievalware, Infomaster, PartNet, GeoSphere, etc.
