• Act as software developer for the Bioterrorism Program's Health Electronic Response Data Systems HERDS for hospitals, schools, nursing homes, home care and adult care facilities. The HERDS applications are designed to collect information from the various facilities using dynamically created surveys. These applications are running in a J2EE Oracle Weblogic application server environment. I supported the Form Designer/Viewer application that has been created to allow for forms to be designed in a standard method and included in any application that follows our framework. Responsible for supporting the existing HERDS applications and helping to design and build a new more generic HERDS application that can support any facility type. Duties included: Designing, developing and maintaining java based jsf web pages data validations and page navigation , java business classes and enhanced specialized data access modules which use Spring DAO and iBatis. In some java classes, I modified many business rules used to retrieve user's permissions and facilities by consuming web services. This was required to summarize permissions read only, read/write and extract appropriate facilities based on user's login input login user type: state, region, school district from Department Of Health centralized database. Java classes are designed using common design patterns such as Iterator, DAO, Value Objects VO and business delegate. Also created and enhanced Oracle stored procedures and functions used in data migration from Sybase to Oracle databases. Provide expert data base design assistance for the development of complex logical data models. Experienced in Oracle database Design, creation, modification of tables, views, SQL queries and triggers, stored procedures, functions.

• I contributed part time, evening/week end on creating/designing front end web pages: Customer, Order and Manufacturer. I added data validations required, numeric only fields, email address valid format and business process in java classes, Spring controller object, for navigation purpose. We also made use of JPA to store the persistence data in MySql. I also modified some POJO classes JPA entity object to reflect table changes/enhancements as per business requirements or setting relationship between entities. We also used annotations instead of mapping files.

• Supports NYSDOH maintaining the CDESS application in a J2EE Oracle Weblogic application server environment. Adds new diseases to the CDESS application and participates in walkthroughs with other CDESS team members for application design and database enhancements. Creates technical documents including a database entity relationship diagram ERD and maps the documents for walkthroughs as appropriate. Designs Sybase database schema to support the integration of new diseases and created SQL statements to retrieve and update data in CDESS tables. Performs unit and regression testing for each new disease and report to ensure the CDESS application still execute flawlessly. Creates SQL statements to generate reports based on the user's input criteria.
• Using the SOA architecture of the Health Commerce System HCS framework, I added CDESS features to call a web service required to retrieve data from OMS tables. The web services is part of the HCS Framework.
• Created JSP forms and Java business classes, including servlets and data persistence objects used with JDBC objects. Java classes are designed using common design patterns such as assembler and Value Objects VO business and delegate. These are specific for each new CDESS disease. Modified XML configuration files for CDESS navigation and webpage layout are also employed. Validate user's input using JavaScript client side business rules before data is transferred to the database for query or updates. A special project included integrating Perinatal Hepatitis B Infant Tracking Module into the CDESS application.
• Coordinates future CDESS implementations with other Developers and participates in the technical design, development, and implementation of application systems. Designs and codes programs, creates test transactions, and runs tests to find errors. In an Oracle Weblogic Workshop 10.3 environment, developed the Outbreak Management System OMS , a new web-based application developed in Java. Creates JSF pages and servlets and updated XML configuration files required for navigation purposes. Develops OMS business objects needed for specific business functions including web services. Extracts data from OMS tables and provides online validations, navigation, and security/permission authorizations. Using JavaScript, validates user's input before sending transactions to the CDESS database. Creates CDESS and OMS Java classes and sequence diagrams based on recognized IT design patterns. Attends sessions with expert users to review use cases. Creates OMS tables using Oracle 10g then updates using the iBatis persistence framework. Used SQL Developer for creating Oracle objects including tables, synonyms, views, and sequenceKey. With the help of a Database Architect, optimized various tables and created physical models for future reference. For both CDESS and OMS, code reuse and object oriented methodology were successfully in implementing new CDESS features and having OMS implemented on time.
