Java Developer

Responsibilities:

• Created a large portion of the adapter code, which took data mean to be added to SQL code and instead used it to create objects to be sent to the database as JSON objects.
• Helped to create the Couchbase database connector, which connected to the database, opened buckets, retrieved data from the buckets, and saved data to the buckets.
• Wrote views in the database and later implemented the reference docs which replaced the views. View querying was found to be not efficient enough. These primary-foreign key pair documents solved the issue.
• Carried out the creation of the TTL system for the JSON document objects, as well as the beans that were purely kept in memory.
• Spent many hours testing and fixing integration issues through the help of SoapUI and JUnit testing.
• Backup data sent to Oracle through Kafka
• Created builds through Hudson, to be deployed on the WebLogic server
• Handled version control through the use of Tortoise SVN
• Configured Spring to work with new classes and beans
• Paas usage enabled the storing of applications on the cloud
• Used generics for creating general methods, for the purpose of building view queries, creating JSON objects, and structuring a save to database method that worked for different object types.
• Common collections used included ArrayLists to store main bean types within another class object, as well as to store multiple beans retrieved from the record of one customer. Sets were used to store multipe variables in one field of a bean, such as addresses or account records of one customer. Hashmaps were used to keep track of key value pairs, to enable pushing backup data to Oracle through kafka.
• Multithreading implementation broke up the process of taking user submitted data and sending it through different validation processes, before going to the biller.
