IBM UrbanCode Deploy:

• IBM UrbanCode Deploy, formerly known as Udeploy, is a GUI-based deployment automation tool that provides you with the tools you need to orchestrate and automate the installation and deployment of IBM Sterling Order Management. It facilitates fast deployment, enables you to deploy as often as you like, on demand, on a schedule, and with self-service, while shortening the time to market.

Achievements/Tasks

1. Java Application Development:

• Designed and developed scalable Java applications using object-oriented programming principles.
• Built multi-threaded applications for improved performance and responsiveness in high-concurrency environments.
• Integrated third-party libraries and APIs (e.g., RESTful services) into Java applications for added functionality.

2. Backend Development:

• Developed backend services and RESTful APIs using the Java and Spring Boot framework.
• Implemented and maintained a microservices architecture with Java to ensure scalability and flexibility.
• Worked with Java frameworks such as Hibernate and JPA to manage database interactions and ORM (Object Relational Mapping).

3. Database Integration:

Developed SQL queries and integrated relational databases (MySQL, IBM DB2, MS SQL Server, and Oracle) with Java applications. Optimized database queries and implemented caching techniques to improve application performance. Managed transactions, stored procedures, and triggers in Java to interact with databases.

4. Software Testing and Debugging:

• Wrote unit tests using JUnit and TestNG to ensure the quality and reliability of Java code.
• Utilized Mockito and other mocking frameworks to test components and services independently.
• Applied debugging techniques using Java IDEs (IntelliJ, Eclipse), and profilers to identify and resolve performance bottlenecks.

.5. Version Control and Deployment:

• Used Git for version control, ensuring code integrity, and collaboration in agile development teams.
• Implemented Continuous Integration (CI) pipelines with Jenkins and Docker for automated testing and deployment.
• Worked with deployment tools like Kubernetes to deploy Java microservices in cloud environments (AWS).

6. Code Reviews and Mentorship:

• Conducted code reviews for team members to ensure adherence to coding standards and best practices.
• Provided mentorship to junior developers in Java programming, design patterns, and the software development lifecycle.

Technologies Used

• JAVA, J2EE, Spring Boot, Hibernate, DOJO, JSP, JUNIT, Mockito, PL/SQL, ActiveMQ and Angular.
• Microservices architecture.
• Web Services – AWS.
• Docker - Kubernetes.
• Platform – Unix, ANT, JIRA, Maven, Git.

Process-as-code feature:

Programmatically manage processes with PAC language. The process-as-code feature (PAC) lets you use the command line to create IBM UrbanCode Deploy processes. You can create scripts that define processes, and then upload them to the server.

• Design and development of a Java-based application integrating ANTL for parsing custom syntax.
• Develop grammar for the custom DSL (Domain-Specific Language) to be recognized and processed by the ANTL parser.
• Implement Java classes for parsing input, processing the parsed data, and outputting results to the user.
• Error handling and debugging mechanisms provide feedback for invalid syntax and enhance user experience.

Technologies Used

• JAVA/J2EE, JUnit.
• Framework - ANTLR.

Level 3 Customer Support - Technical Specialist

As an experienced Level 3 (L3) Customer Support Specialist, I provided advanced troubleshooting and resolution for critical customer issues, focusing on performance tuning, system analysis, and optimization.

• Thread Dump Analysis: Analyzed thread dumps to identify deadlocks, thread contention, and performance bottlenecks in Java applications, providing actionable insights to developers for issue resolution.
• Heap Dump Analysis: Utilized heap dump analysis tools (e.g., Eclipse MAT) to identify memory leaks, excessive memory consumption, and inefficient garbage collection, leading to improved application stability and performance.
• Query Execution Plan and Explain Plan: Employed query execution plans and query explain plans to troubleshoot SQL performance issues, recommending index creation, query rewrites, and other optimizations to improve query efficiency, and overall system performance.

Achievements/Tasks

• Oracle Configuration Manager - With the introduction of New Generation CCR (ngccr), the protocol for collecting and uploading client configuration to the repository has changed. Adapter servers serve as a means to collect and upload configuration data in the older format from the client and convert it to a format understandable by ngccr, then upload it to the new ngccr repository. The adapter has mainly two components: the receiver and the loader. Receiver process receives the config data from client whereas the responsibility of Loader is to parse the data and process it to store in to the ccr repository. As an individual contributor, I was involved in developing, maintaining, and resolving critical issues for the Adapter server.
• Harvester: GC Harvester is a key component of Oracle Enterprise Manager (EM). The EM job is to monitor and manage other Oracle products, and the harvester is a key component of EM whose responsibility is to collect the configuration information for the targets managed and monitored by EM and upload it to the CCR server. As a member of the OCM team, I was involved in developing and maintaining various enhancement requests, and resolving critical issues.

Technologies Used:

• Java/J2EE, JSP, PL/SQL, JPA.
• Unix, Ant.
