Met Requirements: High performance to conform with SLAs // 10 million+ calls/month on average in the live-system // flexible API for integration by developers and/or administrators (JMX, annotations, configurable aop-pointcuts...) // high test-coverage // connection to 24/7 supervision-systems // enterprise-logging // offshore-enablement due to intuitive and complete documentation // component is integrated in two mission-critical systems from the start and is recommended to be used in new systems. By now the component is also used as data-provider for other systems.

Right from the start the design concept included Software-as-a-Service (SaaS) and Cloud Computing functionality. The solution was designed and developed on Grails Basis.

Seach engine optimised Satelite Portals where launched and placed in market niches. The Portal Software was realised on Grails Basis and is connected with the Online Platform.

Provided a central hub according to the specifications of the („Committee of European Securities Regulators“) a highly configurable transfermanagement SOA with declarative business-process modelling capabilities for collection and processing of data of European financial markets was developed and sucessfully integrated.

Conception, realisation and integration of a custom Java Enterprise module for the main application of the customer. Module helps agents with identification and controlling of vehicle-interval groups and their potential time-differences. Problems can be analysed by configurable algorithms and resolved to decision-supporting options.

A realtime-OLAP solution based on the Open Source JasperSoft BI products were planned and delivered via a prototype. Existing reports were migrated, new dynamic reports were created and ETL-processes were developed that provide the possibility to constantly analyze large data-sets with small latency.

The framework was reviewed, considering the requirements and a backwards-compatible solution resulting from the following tasks was deployed:

• separation of application- and infrastructure-logic via proven design-patterns
• optimisation of the modularity und usage of the API
• training of the development team, creation of coding guidelines und code-templates

• Conception and modelling of the data-dependencies, extensive data-imports and data-conversions
• Testing of the application via unit- and integration-tests (test-coverage > 80%)
• Measureable quality control by static code analysis (no PMD or compiler warnings, no duplicate source-code)
• Outsourcing of work-loads and integration of deliverables

• Development and maintenance of seven intranet-applications and six secure and accessible internet-applications
• Migration from EJB to Spring
• Introduction of an automated test-environment
• Creation of java-libraries for reuse in projects
• Establishment of an automated deployment and configuration in a WebSphere environment
• Refactoring of a JAXP transformation-service (XSL-FO)
• Creation and integration of rich-internet components

Technological review of a large information-system (development time: > 2 man-years) regarding the system-architecture, overall conception and the latest source-code. Formulation of proceeding recommondations given technological constraints. Showcasing of an alternative system-architecture based on the spring framework.

A prototype showcasing the target environment and architecture was developed and demonstrated live during a large  investor meeting in this very compact project. Development included a custom UPES ("User Defined Program Execution Server“) that was accessed by an enterprise service bus (ESB). Additionally, a web services implementation based on Apache Axis and Java Web Services and modelling via the IBM Rational Software Architect was part of this project.
