## BIO **Master of Science in Computer and Information Science** The Ohio State Univeristy, Columbus OH **WORK EXPERIENCE** ***Webmaster and DBA*** Designed and implemented a Web application using ASP, VBScript and JavaScript for an Update Protocol to submit data records to database. The development environment consists of MS SQL Server 7.0, ODBC, Windows NT, IIS 4.0. This project also used Transact SQL programming to design stored procedures and to manage concurrent submissions. ***Senior Software Engineer*** Technical lead responsible for the design and implementation of a new management software, an intranet application to control general transactions, customer support accounting and business management tasks for a mid-size company. Sun's Java Web Server, Java Servlets, Java 1.1, and Oracle database via JDBC were used to construct an enterprise client-server architecture. Wrote the requirement and design specifications and coordinated a team of engineers throughout the development. ***Software Engineer*** Developed a new Warehouse Management software and a Product Registration Database for the pharmaceutical products imported under the World Bank Project. Coordinated and centralized computer reporting of 18 regional and national pharmaceutical wholesale organizations. This project involved design and development under FoxPro 2.6 for Windows. ***Lecturer*** Engaged in analysis and design of an intelligent system for computer assisted medical diagnosis in genetic dysmorphology and neurology. The goal of the computer assisted diagnosis was fully achieved by selecting syndromes based on association rules between codified symptoms. The software was developed in C++ using a large database created with DBase IV. **OTHER PROJECTS** ***Architecture for Web-Based Information Systems*** Designed and developed a Java based wizard to facilitate generation of new Input Forms. The wizard was itself an input form to support the specification of the screen names, menu items, selection and input fields, navigation targets and Oracle database components. A client-side framework determined the layout and properties of the new form components. ***Relay Chat Program*** A multi-channel chat-like program written in Java using Remote Method Invocation. Implemented a server providing the naming mechanism to map unique user handles into their RMI connections, and a client applet allowing users to communicate with the server. ***Messengers and Bandits*** Developed a chat-like application for mobile agents using Aglets 1.2.0 where messages were delivered by messenger mobile agents while other mobile agents tried to tamper with the messengers. The goal was to identify and solve the security problems such that messengers were protected against all kinds of tampering attempts by the malicious mobile agents. The solution I implemented used the Diffie-Hellman key agreement protocol for data encryption and Java Cryptography Extension (JCE) 1.2.1. ***Web log mining*** Analyzing the web access logs to understand user behavior in order to improve the web site navigation, the design of web applications and the server performance. The goal was to provide in depth reports on sequential pattern analysis and Web accessing association rules. For the click stream analysis, first the Web log file was cleaned and filtered to generate a relational database. In the next step, AprioriTid was used to generate all the patterns and the uninteresting ones were filtered out. ## Area of Expertise **Languages:** SQL,Java, C/C++,VBScript,JavaScript,Visual Basic,XML, UML, FoxPro,DBase **Databases:** MS SQL Server,Oracle,MS Access **Java Technologies**: Java Server Pages (JSP),Java Servlets,EJB,RMI,JDBC,JCE **Other Technologies**: MS Active Server Pages (ASP), Aglets,CORBA **Tools:** SQL Server Enterprise Manager,Query Analyzer,JBuilder,Visual InterDev,Visual Studio,MS Office, XEmacs **Operating Systems:** MS Windows 98,Windows NT,Windows 2000,UNIX,DOS
