Upgraded the application to Java 8 (refactored lots of loops to stream, replaced java.util.Date with Java 8’s Date Time API), Hibernate 5.2.x (to persist Java 8’s Date Time classes correctly), Weblogic 12c.
Applied concurrency programming to fetch and process data from different sources.
Refactored, rewrote many parts of the application to easy to understand, maintain and test.
Wrote many new tests using the Spock framework.
Fixed bugs, added new features and wrote tests for them.
Convert this Struts-based application to Spring MVC.
Global Securities Transaction Management framework:
Used Java 8, Spring Boot, Spring Cloud and Netflix OSS to implement a microservice environment with a proxy service, many web services (providing html pages) and many resource services (providing data in json format).
Used Spring Security, Spring LDAP, Kerberos and JWT to provide securities for REST services.
Gradle as a build automation system.
Exception Finder application:
A Scala application built from scratch to periodically aggregate exceptions stored in a variety of systems' database, store them in them in its own memory and show them in one UI.
Users can suppress or resubmit an exception to close it. That triggers the application to call a stored procedure in the original system's database (the one catching the exception in the first place).
Scala, ScalikeJDBC and Scalatra web framework were used.

A facility tells how much money a customer borrows or wants to borrow the bank under which products (loans, credit cards…).

While a facility is being edited (it can takes months), it is saved in the MongoDB. After a facility is approved, it is stored in Oracle DB for other systems to see. manages the collateral life cycles. Collaterals are used for a facility and are used as one of many factors to decide if that facility should be approved or not. covenants are conditions on customers. If a condition is not met, the customer might not be able to borrow the money from the bank.
