Java/J2EE Developer

• Worked with different teams to gather the requirements and implement the features and did the enhancements
• Created utilities (in jar files forms) to be used across multiple teams. For example, created utility to read and cache the properties file at scheduled interval, return the current property values if requested, and allowing the listeners to register themselves and follow up actions if any property changes while application is running. Another example is to have a utility, which takes service request object and properties file as input, generate authorization token, call a specific email application with request and authorization token, capture the response of email service, and return the response of email service.
• Developed the module which is responsible for fetching the validation code when the user provides feedback, and sent it to different email address depending upon which locale the message is in, i.e depending upon country and language for which the feedback was received.
• Worked with GIT Workflow Methodology, Jira tickets forking into features/branches/bug fixes and merging after pull requests with team.
• Consumed services of other teams, and exposed our services to be used by customers.
• Used a collection of Java J2EE frameworks to build the application, those frameworks were JSF 2.0, Primefaces 3.5, Spring 3 and Hibernate 3, Maven, POI, Jasper Reports and Junit.
• Enhanced the feature to allow emoji and other symbols in different fields of different services. This includes the most recent versions of emoji/Unicode symbols as well
• Created JUnit and TestNG test suites for different modules, including the features I developed/enhanced.
• Responsible for deployments of the application in pre-production environments.
• Worked on various bug fixing for the bugs reported by QA and other teams.
• Documented the usage details of the feature I developed
• Worked with multiple teams to analysis the errors in log files, figured out the reason of Errors, and fixed them in pilot environment before going to production or raised bugs with other teams if the issue existed in their system.
