Confidential - Melville, NY

Java / J2EE / Back-end Technical Lead

Responsibilities:

• I learned how to make business templates in IBM Web Content Management. These generate responsive html5 pages using bootstrap and JQuery.
• One advanced template I modified was a 3 topic showcase ribbon that showcased product content in 3 columns on the page. I added new authoring content fields, and added titles above an image and above a description text area.
• The 3 columns were made responsive by shrinking down to 2 column then 1 column as the width of the browser window decreases. Users could also optionally add a YouTube video or image to show below the title of each column.
• I updated a JQuery product filter so that it counts how many items have the features selected. Previously it was counting from all the items. This can be seen here:.
• Research and fix the N+1 hibernate query performance issues with our DAO layer
• I worked with our Business Partners to meet with Third Party Clients to propose and design solutions. One client included Golden Eagle Sales Performance tracking site. I performed Technical Lead duties for an SSO pass through project with Golden Eagle so sales people can register sales and redeem rewards.
• We provided a link to the GE site from the Confidential site, and when clicked, if the user is authorized, automatically grants them access to the GE site without having to log in.
• I designed the Technical Design Doc(TDD), worked with Business to meet and discuss any issues with GE
• I developed an Autosys batch process using Spring Boot and Java 8 lambdas to fetch the list of authorized uses and send to GE on a weekly basis. GE then uses this list for the valid users eligible for Single Signon (SSO) pass through.
• Attend code reviews of other developers on our team, provide suggestions and improvements to existing code base
• Track work items in Jira along with time spent and attend monthly sprint planning meetings, and daily stand ups
