Java-server- and -client-development for 4 existing applications aimed to support Credit-Risk-Management.
Company size: < 5000 persons
Department size: <= 30 persons
Industry sector: Banking, Financial services
Rough description of the systems:
-
Transaction Monitoring
Web-application for monitoring of the structured and partially corporate credit portfolio. Single deals and borrowers are monitored from disbursement until final maturity of a transaction. Analysts get reminders for overdue reports and unmet conditions and are supported in preparing annual credit reviews.
Core components: Definition of deals, related contracts, transaction parties (borrowers and others). Tracking of approval, deal development, collaterals, credit reviews, covenants, periodical reports. Report creation (Excel, PDF). Calendar with deal-specific events. Automatic e-mail-sending.
The application uses a proprietary Web-MVC-framework built on top of Apache Struts and gets data from other systems of the bank (customer-, rating-data, etc.).
-
Workflow tool for credit processes
Web-application used to support credit processes mainly for mid-cap business including origination, booking, documentation of information relevant to the credit request and covenant monitoring.
Core components: Entry and processing of credit request, first vote, covenants. Monitoring of covenants. Checks for consistency by business rules. Notification of process participants via e-mail. Automatic data-retrieval (also from other systems of the bank) like profitability calculations, balance sheets, ratings. Storage and conversion of MS Office documents.
-
Portfolio Management System
Web-application delivering reports about exposures, risk capitals, P&L amount, collaterals for each deal including client information like ratings, industries and groups. Providing parameters enables filtering and grouping of report-data.
-
Tool for contract documents generation
Rich-Client-/Server-application for generation of contract documents for credit business like credit contracts, collateral contracts using predefined text-components and individual data maintained by users. Legal correctness of the documents is assured through a rule framework. Text-components are stored in XML-format. PDF documents are generated via XSLT and XSL-FO.
2nd- and 3rd-Level-Support for these applications. For (1) including world-wide subsidiaries.
In the transformation process in which the bank is transformed into a financial service provider, the systems are re-branded and enabled for multi-tenancy.
For system (1):
-
Implementation of framework-upgrades (Spring, Hibernate)
-
Partial optimization of the architecture
-
Migration from Java 5 to Java 6 and from WebSphere 6.1 to WebSphere 7
-
DB-migrations are done via Flyway DB

Company size: > 100000 persons
Department size: > 200 persons
Industry sector: IT, Telecommunication
During project duration the following main tasks are accomplished in a multi-national environment.
Java-client-development: Extensions and new functionality is being developed for the shop-application (Rich-Client-Java). Bug-fixing and code-review is done for existing as well as for newly developed code. New unit-tests are created and existing ones extended, corrected and enhanced. Single application modules are implemented in form of Eclipse-plugins using an existing MVC- and Dependency-Injection-framework developed in house.
Java-server-development: Extension of existing Java-classes of the server application. The server communicates with the shop-client via HTTP/XML and with other back-end systems via defined interfaces. Besides other things XML-data has to be validated and transformed via XSLT. Unit-tests are created, extended, enhanced and fixed. Branch-and-merge: Various development branches are merged.
Hudson/Jenkins CI (Continuous Integration): A Jenkins-system (former Hudson) is being configured as replacement for an existing CruiseControl system. Projects managed in a SVN repository are set-up. Ant-scripts are modified according to the new systems' requirements.
Document-review: Reviews of business requirements documents are done.
Conceptual design: Solution concepts are created based on business requirements and brought into agreement with the final customer. Development is mainly done by offshore-developers.
Coaching of offshore-developers: Offshore-developers are supported during development of new software components and solution concepts.
Incident-/Problem-management: In case of occurrence of problems or errors in the software, these are managed in a JIRA-system. The incident-/problem-manager is the immediate interface to the customer to agree prioritization and further processing according to SLAs (service level agreements). Tickets are assigned to the responsible employees and their processing in connection with delivered and planned releases is being tracked.
