Senior Java Developer

• Confidential needed migration of the existing foreign exchange system that was implemented in legacy technologies. Project’s initial phase involved reengineering of a few modules that were already migrated into java swing technologies. This reengineering is to address some showstopper issues and to systematize the future migration process.
• The later phase involved the migration of the total system into java technologies complying with the framework standards laid out in the initial phase of reengineering. Developed a reporting module for the FOREX deals follows this.
