Oracle ADF Consultant/Software Engineer

MedNet International
(2 years 11 months)

Oracle ADF Consultant/Software Engineer. During the last year, I was fortunate to participate in one of the first attempts to migrate an old big scale Oracle Forms 6i application (around 250 forms) to Oracle ADF 11g (more on Oracle Success stories).
Reengineering the old application in order for the new application and the old one to work in parallel imposes extra difficulties as it was necessary to respect the approach of the old app. During the project I was involved both in developing (in my first months), design reviewing and developer’s assisting:
• Developing using all the features that the ADF framework provides such as: ADF Business Components, ADF Task Flows, ADF Faces Rich Client (JSF, ADF rich AJAX components, Trinidad components etc). Also I was partially involved in the deploying of the application on clustered Weblogic 11g (10.3.1) server.
• Designing: Although ADF is considered to be maybe the best choice for migrating a Forms application (Client-Server) into a web based one, unfortunately there are some incompatibilities and problems when trying to implement the same functionality in Forms. During the project I was also involved in providing the proper design based on the analysis of the functionality of the existing Oracle Forms 6i application, so as to provide solutions in order for the migration to be feasible.
• Reviewing: Code reviewing, inspecting the implementation and functionality of the work performed by developers, checking the developing decisions that were adopted, verifying that Company’s Developing Standards were followed in order for the deliverable to reach the expected quality state before Testing.
• Developers’ assisting: Helping developers to workaround problems, implement the functionality by utilizing the framework features and avoiding discourage practices.
