PROFESSIONAL EXPERIENCE:

Confidential, Atlanta, GA

Senior Java EE Developer

Responsibilities:

• Digital Notifications serves as a reusable way to send notifications to the customer or internal user with order status and details. Using Selection Logic that is unique to each Service or Product Offer, the Platform is able to derive from order data what notification needs to be sent, whom to send the notification to, what data to populate on the notification, as well as if a customer has requested not to receive notifications entirely.
• The key process steps in the service to create and send Digital Notifications (DN) to the customer are: Trigger to Initiate a Digital Notification (API calls by External System to hosted Web Service by DN), Template selection rules (Groovy),
• Determine Data Elements from selected Template (Groovy-Regular Expressions), Retrieve Data Elements value
• (Web Service call to API's of select external systems), Populate DN document and validate (freemarker a Java-based Template Engine), Apply Mail blocking rules, Store, log, & distribute email where applicable, Fallout - Generate CTH Exception Task for correct action and context of order status (DN calls Web Service hosted by Common Task Handler (CTH) which in turn updates Workflow order status accordingly).
• (a) Search History for Notifications generated against a: Customer or Order, (b) Resend or Regenerate Notifications for a Customer, (c) Mail Blocking rules, allowing an administrative user to be able to define what customers or orders will not receive notifications, (d) Template Administration - Administrative users will be able to edit the selection logic for templates, view template history, preview notifications as they are updated, and verify content. (e) If the flag is set on a template, record keeping systems SXP/ Order Status Manager (OSM)/ Integrated Order Status (IOS) will receive a copy of the notification upon sending (f) Administrative Users will be able to define, copy, edit, and delete templates via a What You See Is What You Get (WYSIWYG) Editor. (g) Development team will be able to - rapidly build and deploy a new template that is Templates are data driven.
• Developed a module packaged as EAR which involves (a) a Web service call to external system to Retrieve Data Elements value for a template, (b) a JMS call to/from DN-Core-Module to this new DN-ExternalAPIcall-module to pass over request info that is used in making Web Service call to external system & receive retrieved data elements value (c) a rest Web Service call from DN-UI-Module to this new DN-ExternalAPIcall-module.
• Based on data elements identified on a selected template a few (about 4 to 6 from a total of 19) Web Service calls (to External Systems) & JMS/Rest Web Service calls (between 2 EAR modules internal to DN) are made to transfer data. For data transfer between EARs, JMS call preferred where Notification for a selected Template is not yet generated versus Rest Web Service call preferred in where a Notification for a selected Template is already generated but a user using GUI prefers to regenerate a new Notification.
• Developed new templates that have TO, CC, BCC, Subject, body, attachment, an Enum used for admin control & also in template selection, Acceptance Criteria that is used in template selection. This new template is added to the database by running a data driver and is shown on UI retrieving it from database via a web service call from DN-UI-Module to DN-Core-Module where the Service is hosted.
• Digital Notification has following implementations: about 19 Client Web Service Calls, most of these External API calls are pkg'd in one EAR except for a very few.
• (Based on list of data elements on a selected template a few external API’s are invoked) (b) About 19 JMS calls to/from DN-Core-Module and DN-ExternalAPIcall-Module. (c) Rest Web Service calls between DN-UI-Module and DN-ExternalAPIcall-Module as needed.
• On development environments ExternalAPICalls are avoided, instead simulator responses are setup. Periodically updated simulator responses picked from logs of production and/or UAT environments. Also periodically updated templates on development environments with admin updates made to those templates on production.
• Involved in grooming User Story’s (created in Rally) with System Engineer. Added tasks to User Story’s for few iterations thus helping development team in understanding work units. Assist incoming System Engineer during grooming calls.
• Support Production, User Acceptance Testing, System Testing & On development environments tested notification generation for given service using responses setup on simulator.
• Involved in Test Automation Development using fitness & Selenium.
• Read through Application Interface Design documents of External Interfaces. Update Interfaces Schemas & WSDL.
