• MAARS Presentation tier utilizes HTML with embedded Java Scriplets, and JSP that communicates with the business logic tier through a Java Bean. The Web server and Servlet/JSP container utilizes by MAARS are two Open Source standards, the Apache Web Server and Tomcat.
• The Business Logic tier Java Bean is designed to handle multiple users by assigning each user to their own class object that is stored in a Hash table. The user session id is used as the key to their object in the hash table. The Java Bean also utilizes socket connections to communicate with the Context Manager Server tier.
• The Context Manager Server, CMS, tier is an in house developed multithreaded Server process written in Java. The CMS opens a socket connection to receive requests from the Java Bean. Once a request comes in the CMS then creates a class object for the time the user session is open. The CMS allows multiple operations by opening a thread to handle each client’s request to its object. Once each operation is completed the CMS null all variables that belong to that object and then record its usage to the data store, the fourth tier.
• Designed the database, tables, relations and store procedures of the data store. The data store used is postgreSQL, an Open Source database.
• Based on the requirements from the federal government PBDMI, Performance Based Data Management Initiative, developed a PL/SQL program that retrieves data from the MSIS, Mississippi Student Information System, database and converts it into a XML document. The document is then passed to the federal government and added to their national database.
• Worked with the Office of Curriculum and Instruction, Office of Accreditation, SPED and the Center for Teaching & Recruitment to develop the process of determining the highly qualified status of the teachers of Mississippi. With the information obtain from the four offices I then developed the logic and the PL/SQL program to report the state highly qualified status to the federal government. This information is used to obtain and keep Mississippi No Child Left Behind federal approval status.
• Developed PL/SQL programs to create ad-hoc reports requested by the State Board of Education and other federal, state and city governments.
• Developed, and taught, in house training for PL/SQL programming.

Lead Software Engineer

Responsibilities:

• Developed a middleware application in C to move data from Wyeth in house data store to Confidential Manager. The application reads in a XML file, translate the data that it contains into PL/SQL, insert statements and stored them in a file. The file permission is changed to executable. The location of the files and the names of the files along with the output directory are read in by the application as environment variables allowing the ability to change locations without having to recompile the code. The environment variables are place in the startup shell script that executes this application.
• Developed a Java application that is the main interface to interact with the Session Manager. This Java application has a JFrame GUI. This GUI has a JMenuBar with a hard coded File menu built into it. The remainder of the JMenuBar is built dynamically by a Class that receives a list of menu names and subtitles with there arguments. The Class first takes the menu names and create a JMenu object with them. The Class then converts the subtitles to a JMenuItem object and add it to the new JMenu along with an ActionListener placed on it. The Class takes the definition of how to execute the subtitles and a list of there options and place them in a container. When the subtitle is selected the class checks the container to determine how to build the execution process of the selection. If there are options, a new JFrame is built and displayed to collect the User choice(s) to complete the execution process. After the execution process is built the application then executes the selection and awaits the next command.
• Developed a Java JNI method and C library to connect the Data Manager Server that runs the DiBrowser to the calling Java client.
• Developed a Java class with the ability to take a full path name of a file, read that file, and generate a JTree and CustomRender method to handle the opening and closing of the JTree inside of a Java client.
• Developed a multithreaded C server with embedded lex & yacc, the Session Manager. The server accept requests from a socket connection. As each request is received, the server creates a thread to handle that request. The thread setup the initial environment for the execution of the request. The last step for this thread is to start two new threads. One, the worker thread, to execute the request. The other thread, timer thread, is to account for the elapse time to determine that the worker has not exceeded its time limit. The worker thread takes the request string and pass it to the lex & yacc function that separate the string into tokens. Once the command and any additional environment variables are set, the worker thread then executes the request.
• Developed several PL/SQL store procedures for the Data Manager to utilize. After realizing that a number of these procedures were common in relation to the type of processing that they perform, three Oracle Packages was created to Separate the common procedures.
• Used C++ to develop a graphing tool for integration into the DI Browser, (Discovery Informatics Browser). This was done in collaboration with three team members. The tool provides the ability to quickly generate graph images (gifs) on the Data Manager Server for inclusion in the browser result sets.
• Developed a project in C that handle the migration of the Disparates Analysis to the new XML internal format for the DI Browser. In addition to the output reformatting, drilldown links for similarity searches were added. Also, the code was cleaned up and split into smaller functions to allow future reuse of some of the ability of the tool and to allow easier modification when enhancements are required. The tool accomplishment its task by setting up a shared memory segment that sub processes that was fork() off would place there findings into, allowing the parent process to take the results and stored it into an XML format.
• Developed a project in Perl to do some tweaking to the scripts which mine structure information from the Competitive Surveillance web site. These scripts sift through files looking for SMILES strings and URL links pointing to the DI Browser. Some characters in the SMILES strings need to be protected when utilized in a URL link (# or + for example), so the scripts modify the files. Also, the scripts extract the SMILES strings and the location from where they were found then used to build a database of structures for integration in the DI Browser. When structures were found from this database, the DI Browser was able to provide a link to the source in the Competitive Surveillance.
• Created a C tool to check a collection of structures for uniqueness against the current PharmaDB, DayLight. This tool will be integrated into the DI Browser to facilitate processing of vendor libraries. The tool takes the library of structures, removes salts, generates canonical SMILES strings for the remaining parent structure, and then compares the canonical SMILES string to the Oracle database of parent SMILES strings maintained by the registration system.
