Confidential

Sr Software Consultant/Architect

• Created a generic RESTFul WebService that accepts an SQL query as a parameter, access the reports database, execute the query, and build and return XML report from the result set. Since Macys has database tables for reporting purposes, this project works in any environment and literally for any project due to its generic nature.
• Java, JBOSS, RestEasy are the technologies used.
• Agile/Scrum methodology is used.
