Responsibilities:

• Determined and eliminated system performance bottlenecks and deadlocks related to CORBA and database connection pooling
• Responsible for the improvement of a workflow, web-based order fallout processing application, which was having serious reliability and maintainability problems, preventing it’s use in production. Applied well-known object-oriented techniques, design patterns, refactoring and UML diagrams to improve the reliability, code quality and design of the application, which was based on Java, JSP, servlets, JDBC, CORBA. As a result the system achieved production grade stability, maintainability and flexibility, and was ready to replace an existing legacy system. Used C++, X/Windows as a code for the above workflow solution.
