PROFESSIONAL EXPERIENCE

Confidential, Springfield, IL

Full Stack Java Developer

Responsibilities:

• To re-write all the Child Care Management System (CCMS) screens now using Adobe Flash (developed in Adobe Flex) so that they use industry-standard technologies like HTML, JSF (Java Server Faces), Tomahawk, JavaScript for frontend and Java for backend.
• The CCMS was developed using Adobe Flex to build its front-end screens, which run using Adobe Flash Player and re-write the code in JAVA.
• The Microsoft Website states that “in mid to late 2019, we will disable Flash by default… Users will be able to re-enable…on a browser-by browser basis… By the end of 2020, we will remove the ability to run Adobe Flash…on all Microsoft platforms”.
• There is a common top banner and the top navigation panel which switches between the 9 major screen groups. Each major screen group has a left-navigation panel for switching between one and 19 “screens” in that group.
• It is expected that these 47 screens will develop into around 118 new panels. Front-end and back-end validations will need to be reused from the existing panels or redeveloped, as will queries for inquiry, searches, lists, updates, etc.
• Maintaining the source code on IBM RTC by creating repositories, modify the repositories, branching, merging, check-in, check-out and committing code using RTC team artifacts.
• Developing selenium scripts for automation testing after integrating the modules of the application.
• Perform the optimization of the SQL queries by creating the indexes and normalizing the data and cleansing the data and re-design the tables if needed.
