Aufgaben

FIDS (Flight Information Display System) FIDS is a new product of Fraport AG for storing and displaying of flight information data. It is a distributed asynchronous system. The communication with partner systems is realized with XML messages using JMS. I developed an adaptor component handling the JMS message communication and data persistence Existing code was ported towards the Spring framework replacing old EJB 1.1 code. The adaptor turned into a light weight component Due to the fact that the protocol between the systems increased in complexity I had to implement the adaptor component as a finite state machine (FSM). I used JBoss jBPM as the workflow and BPM engine allowing graph oriented development A further task was the development of FIDS' web based administration console. Due to the sophisticated requirements I decided to implement this web application with JSF (MyFaces) Technical details Java, J2EE, JMS, Spring Framework, JSF XML, XSLT SQL Software: Websphere Application Developer (WSAD), Websphere AS, JBoss, Oracle 8i, MyFaces

SAS Germany eCDMS SAS solutions are specialized for processing of statistical mass data. This mass data is typical for medical studies. Before the data of medical studies can be processed it has to be collected. Medical studies differ in structure and size. SAS eCDMS is a generic system for structural definition, operative collection and evaluation of medical studies. The operative part of eCDMS is a web application whose data structure is defined by the underlying medical study. The layout of the graphical user interface can be defined independently by the customer. The web application also contains code generators for SAS Base Language und SAS SCL.

Aufgaben

Deutsche Bank (Accenture) eSales Deutsche Bank wanted eSales to be a integrated platform for selling derivatives. This was an offshore project located in Manila, Philippines As an architect I was responsible for the design of several technical foundation services and implementation of prototypes as a proof of concept. I also designed a service for custom (dynamic) authorization and reporting having a n-dimensional, hierarchical right system Required was a component based approach. So services were implemented as stateless session EJBs, which allowed a better scalability. The architecture was highly distributed. Therefore we used JMS for inter business component communication which decoupled the components and added some fault tolerance. The security database was designed with Oracle Designer. Additional PL/SQL was added manually. Due to higher management decisions data access was done with Oracle TopLink or JDBC. Technical details Java, J2EE, JMS, Web services Service architecture for a n-dimensional, hierarchical security system Service architecture for reporting Software: Oracle 9i, BEA WebLogic, Eclipse 2.1, JasperReports

Aufgaben

Landesbank Baden-Wuerttemberg (LBBW) IAS Fair Value Hedge Accounting According to new legal regulations LBBW has to evaluate its hedge business using IAS (International) Accounting Standards). LBBW required a web application for collection and evaluation of these hedges. The web application used an Oracle database which was synchronized with a higher prioritized IAS-Mart (SAS system) I was responsible for the design and implementation of business logic components on the server side The business operations were implemented using stateless Session EJBs. Due to the very simple database structure the persistence layer was implemented using Entity EJBs (CMP 2.0). I also introduced automated testing being a prerequisite for software quality Technical details Java, J2EE, EJB, CMP Unit-Tests Software: Oracle 8i, BEA WebLogic, Eclipse 2.1, JUnit

Aufgaben

Hedge Accounting und weitere Projekte The fusion of Allianz and Dresdner Bank caused a change of the accounting standards to be applied Dresdner Bank had to apply rules of IAS and US-GAAP on derivatives, hedges and loan business The requirement was an intranet web application for collection, evaluation and management of these deals. It should also support quarterly and end-of-year procedures The timeframe was extremely short. Using extreme programming techniques brought the team and me into the position to deliver in time. The solution earned a great deal of praise from the accountants of PricewaterhouseCoopers. Based on this I got several contract extensions Development of a web application for administration, evaluation and management of derivatives, hedges and loan business with reporting for quarterly and end-of-year procedures after US-GAAP Given: tight schedule -> used JSP1 model for a rapid prototype using dbForms. Switched to JSP2 model (MVC) for production using Struts. Some business logic required using JDBC directly which was encapsulated in DAOs. Some batch processing was done via stored procedures in the database directly Automated testing of JSPs und Servlets using Cactus (J2EE-Tests) Development of a JDBC-Realm for Tomcat to access a legacy security database Design and development of a framework based on Struts 1.1 which makes it possible to develop complex, database driven web applications without the need of writing Java code. In general writing JSPs is enough Design and development of an automated, web based reporting software. Customer data, report data and report configurations are stored in databases. The data is converted to XML and transformed into PDF reports using XSLT and FOP. Distribution is done by a separate system, which gets the reports via JMS. MQ-Series is the JMS provider Technical details Java, J2EE, JMS, JSP, Servlets Tomcat JDBC realm for a custom security database Realm for accessing a LDAP server LDAP XML, XSLT, FOP Software: Borland JBuilder 6 Enterprise, Eclipse 2.0, CVS, Windows NT, Unix, Apache Jakarta Tomcat, Cactus, Log4J, Struts, JUnit 3.7, HttpUnit 1.2.5, PoolMan 2.0.4, DbForms 0.9, Informix, MQ- Series

Aufgaben

Emagine / Deutsche Bank Db24 Deutsche Bank offers online banking services over several different channels (BTX, T-Online) Internet). The core of this online banking system is Emagine's Banking Server Platform. The business logic is encapsulated in CORBA components. In addition these CORBA components also have communication channels (MQ-Series) with the legacy systems of Deutsche Bank (EAI) I designed and implemented banking transactions using Emagine's CORBA based Banking Server platform. Security checks were handled by Emagine's own security server. I also created a framework based on the template pattern which made the communication transparent so that other developers could easily create additional CORBA components. This increased the productivity and avoided code duplications There was also the need for a security component for authorized access to a provider for real time data. I implemented a CORBA component (facade pattern) acting as a mapper to a legacy security server of Deutsche Bank dealing with the COBOL data structures of that server I also designed and implemented Banking Server configuration tools in Java. The tools were designed using UML. The persistence package included a special parser developed with MetaMata's parser generator javacc. The GUI was developed using Swing (drag and drop in a JTree was realised with a strict Model-View-Controller (MVC) architecture) Technical details C++, CORBA, Java, UML MQ Series Template pattern, Façade pattern Unit tests Software: Solaris 7, Windows NT, Unix, C++ Compiler, JDK 1.3, Iona Orbix, CVS, Together 4.1 Metamata Parsergenerator javacc, JUnit
