At Network International, I’ve been contributing to the "API Center" project, modernizing integrations by replacing Tibco middleware with RESTful APIs built using Java and Spring Boot. These APIs are developed on local environments and deployed to UAT as part of the client pre-production phase.

The APIs generate Way4-compatible XML requests via internal factories, converting input from JSON to XML to interact with the Oracle-integrated Way4 system. I work extensively with Oracle databases to ensure reliability and performance.

My responsibilities include designing and debugging backend services, writing unit tests with a focus on code coverage(using SonarQube), and documenting endpoints using Swagger. I also collaborate closely with QA for testing and bug fixing, enhance existing APIs for better performance, and participate in refactoring efforts to maintain clean, scalable code.

I take part in code reviews, manage configuration tasks, and contribute to team documentation through Confluence. Development work is tracked using Jira, with version control managed through Git, Bitbucket, and Sourcetree, and deployments supported via CI/CD pipelines in TeamCity and Azure.

This role has deepened my backend development expertise and strengthened my ability to deliver scalable, well-documented, and client-ready fintech solutions.

• GIG Jordan Migration Project(incomplete/without go-live phase)
  A Gulf Insurance Group - Jordan Company migration project for an accounting system from 6i to 12c version(resides on a fully-configured WebLogic Server), and it consists of three parts:
  Part #1 called System Codes which displays messages and errors, can let you deal with different currencies and also add users and set roles for each one of them(System Admin, Auditor, Posting Officer, etc...).
  In part #2 which is called General Ledger, it shows vouchers and a chart of accounts.
  Part #3 called Reports, and it lets you print reports of accounts statements, trial balance and financial & general reports.
• Completed a small Oracle Apex self-project, which is an attractive and modern application for a company leaving system, that helps employees in work leave requests(annual/sick). Once the employee applies for a leave, it is submitted to the Technical Manager with a sent email, who may reject it; if not then he delegates it to the Manager(approved); also with a sent email. After that the Manger can either approve it or reject it. The status of the request is shown to the employee in his profile(pending, approved or rejected). Both Managers can access a full report of all approved leave requests and can also print them as an individual file(pdf). The end-user can use more features such as visiting company's website, displaying its office location and changing his own password.
