picture so it could be easily decoupled from other unrelated issues.

Created the presentation with multiple diagrams containing the various properties of the release process and limiting criteria. These identified conditions were used as a criteria on which any existing or proposed solution could be reliably evaluated prior investment into implementation efforts.

In addition to the analysis I have proposed a solution to the automated delivery which would generally address all the identified questions posed by the problem.

Solution was primarily based on Gradle Groovy and some custom components which were expected to be developed in house.

Achievements

Designed and developed coded the Proof of Concept application as a tool useful for testing and presenting new concepts providing assistance to future developers as showcases and code samples . About 30 screens demonstrating various scenarios situations and configurations of controls dialogs and views in context of the designed framework.

Designed and developed coded small application displaying status and details of current support requests and allowing to manage them The application was implemented coded using the GWT-based framework

mentioned earlier which I created in real-life situation with use of JPA/Hibernate Oracle RDBMS.

Dynamic binding mechanisms of the data to controls

through control properties . Changes in model values immediately reflected in controls and vice-verse. Good separation of Model from View s .

Model components meta data management. For simple data types and complex structures like lists and trees .

Externalization of the static resources into the XML files both values and meta-data . External resources were bound dynamically with data model which allowed for fully automatic reloading content in case of local context switching perfect solution for internationalization purposes .

Data mapping and transfer between server-side and client-side structures. Mapping was specified using Java annotations and inspected using reflection mechanisms. This mechanism was designed specifically to deal with JPA/Hibernate entities and binding them with client-side models declaratively and in fully automatic fashion.

Applied simplified yet powerful model validation mechanisms of complex form data models.

Designed and implement the event and messages handling and display mechanism which uses various display implementations. Structuraly rich messages can be defined as templates and be externalized in form of XML resource files.

Dynamic and externalized styling mechanism where visual appearance of controls and other view

components is kept externally in XML theme files and can be switched on the fly in the run-time.
