Mar 1996 - Oct 1997, Senior Systems Analyst, National Center for Biotechnology Information, National Institutes of Health, Bethesda MD.
Participated in the development of the first Sun Solaris version of the PubMed system for the National Center for Biotechnology Information. Designed and developed the part of the system, which acquires data from publishers and uploads it into the PubMed database. It reads and processes the vendor supplied SGML files encoded using Document Type Definitions (DTD), extracts and validates the NLM specified fields, and converts the extracted fields into formats required by the MedLine and PubMed databases including ASN.1. This system is presently in production. It uploads large numbers of new articles from the leading scientific journals. This part of the system was designed with the Booch approach and implemented in C++, using Sun C++ compiler, RCS and CVS Version Control Systems, SGML, Perl 4, Bourne Shell, and Sybase Open Client CT-Library. Using UNIX crontab utility and Bourne shell scripts the developed loading system supports continuous data flow: taking files from the NCBI FTP site, preliminary processing, parsing, loading to the Sybase PubMed database, dumping new records from PubMed database to MedLine database on mainframe. C++ classes were developed and implemented for the loading system. All actions are documented by the correspondent logfiles.
Also worked on some miscellaneous tasks for the PubMed bioinformatic retrieval system. Created a special dictionary, which contains major SGML entities according to International Standard ISO 8879-1986. Using UNIX shared memory designed and implemented PubMed Journal Server. As well as created a number of CGI programs, which provide WWW interface for the database administrator to maintain data in the PubMed .

Aug 1995 - Mar 1996, Systems Engineer, FDC Technology, Bethesda MD.
Participated in the development of the MS Windows NT version of the Patient Care Information System for Georgetown University Hospital. The task included the development of algorithms and Graphic User Interface, Booch's style Object Oriented design using Rational Rose, Client-Server, Sybase Database. This project has been implemented using Microsoft Visual C++ 4.0, Microsoft Foundation Classes, Microsoft SourceSafe Version Control, and Sybase Database. Also developed a gateway between Novell's GroupWise Mail System and internal database's mail system.
Developed prototypes for Veterans Benefit Administration Information System. This project is implemented using JACC JAM 4GL, Sequent Dynix/ptx scripts, Oracle PRO*C, and Oracle Database.

Jan 1992 - Aug 1995, Guest Researcher, National Institute of Standards and Technology, Gaithersburg MD.
Participated in the development of the MS Windows version of the National Institute of Standards and Technology (NIST) Mass Spectral Database. Task included the development of algorithms and Graphic User Interface, screen forms, reports, help system, installation program, coding, debugging, and testing. This program is implemented on IBM PC running MS Windows NT/3.11. The project is performed using XVT Portability toolkit, FairCom c-tree database, MS Windows SDK, Microsoft Visual C/C++, Borland C/C++ compilers, and InstallShield toolkit. The successful completion of the project allowed NIST to capture a major part of the World Mass Spectral Database's market. Hewlett-Packard bought this system for distribution with all their industrial mass spectrometers. Research and development for modeling of chemical reactions. Task included numerical methods for solving stiff systems of differential equations; development of algorithms, window interface, coding, debugging, testing, and user's support. The project was implemented on IBM PC running MS Windows NT/3.11. Programming was performed using Visual C/C++ and Fortran Power Station Microsoft compilers. The developed program has been integrated with the MS Windows version of NIST Chemical Kinetics Database.
