As a key contributor to the Identity Access Management (IAM) application developed in Java 8, I significantly enhanced its single sign-on (SSO) capabilities for web and mobile apps. I integrated LDAP directly into the application, ensuring real-time synchronization of LDAP data. Additionally, I led the integration of the Microsoft Exchange Server via remote Windows PowerShell, enabling seamless mailbox management within the IDM system.

To streamline SSO implementation across various projects, I developed a modular JAR file easily integrated into other Java applications. This allowed projects to adopt SSO functionality quickly, enhancing security processes. The plugin I created effectively managed unauthorized access, using an API to communicate with the IDM admin panel and WSO2 Identity Server for secure authentication.

For non-Java applications like PHP and Angular, I implemented SSO using JWT tokens, ensuring consistent security across diverse technology stacks. These efforts bolstered the IDM application's robustness, making it a versatile and secure solution across the organization.

Crestel is a telecom product. It provides global business support systems (BSS) and online charging system (OCS) solutions to the telecom operator provider. It consists of all the modules related to the customer lifecycle, including CAAM, billing, system, voucher, and payment.

I was assigned to the billing engine module, which aimed to generate the monthly invoice based on parameters like users' plans, subscription add-ons, offers, and coupons.

The module was built with core Java but has complex logic, database procedure, and functions. Multithreading enabled achieving the desired performance for the operator's large customer base.

We used Jira, SVN, and Bitbucket for the project repository and task assignment. The team had 13 members, including testing and DB members, and because we were following the Agile methodology, we used to have daily standup meetings, sprint reviews, and retrospectives.

This project was mainly based on the management system of resources and employees. It keeps track of all employees' tasks and time duration.

The system was fully automated and contained the following functionalities:
• Add, update, and delete query by authorized customer
• Automatic task allocation to the responsible employees with specific turn-around time (TAT)
• Task escalation to the above hierarchy
• Costumer and solver documents' transfer regarding a task.

We used Java 1.6, JavaServer Pages (JSP), Spring MVC2.3, MySQL, and Oracle with the Tomcat server.
