• Optimized API performance and ensured scalability to support high transaction volumes.

2) Database Management:

• Utilized JPA for database interactions, handling complex queries and transaction management to ensure data consistency and integrity during payment processing.

3) Security and Compliance:

• Implemented security protocols like encryption, tokenization, and OAuth for secure payment processing.
• Ensured compliance with PCI-DSS standards to safeguard sensitive payment information.

·4) Transaction Management:

• Handled transaction lifecycle management, ensuring smooth and error-free operations through robust logging and exception handling mechanisms.
• Managed transaction rollbacks for failed payments using Java’s transaction management features.

5) Collaboration and Integration:

• Worked closely with frontend and backend teams to ensure proper API integration and smooth functioning across all client platforms.
• Provided technical support for troubleshooting integration issues and implemented fixes for reported bugs.

6) Testing and Optimization:

• Conducted unit testing (JUnit) to ensure code quality and accuracy.
• Optimized the API performance to reduce latency and improve overall efficiency of payment handling.

7) Documentation:

• Documented API endpoints, usage, and error handling guidelines to assist other developers and teams in integration.
• CCAvenue Batch Job Scheduler

Technologies: Spring Boot, JSP, JPA, JavaScript, Microsoft SQL Server, Log4j2, Maven

1) Batch Job Scheduling:

• Developed and maintained batch job scheduling mechanisms using Java and Quartz Scheduler to automate recurring tasks such as payment settlements, invoice generation, and report generation.

2) Task Automation:

• Implemented automated processes for tasks like daily reconciliation, payment updates, and transaction status checks, ensuring smooth and efficient batch operations.

3) Concurrency and Performance:

• Optimized batch jobs to handle large volumes of data efficiently, ensuring high performance and minimal downtime during transaction processing.
• Managed concurrent job execution, ensuring data consistency and avoiding race conditions.

4) Error Handling and Monitoring:

• Integrated robust logging and error-handling mechanisms to capture job execution results and failures, providing insights for troubleshooting and recovery.
• Implemented job monitoring and alerting to track job statuses and handle failures or delays in real-time.

5) Database Interaction:

• Utilized JPA and SQL queries to interact with databases during batch jobs, ensuring data accuracy and consistency throughout the job execution cycle.
• Managed database transactions within batch jobs, ensuring proper rollbacks in case of job failure.

6) Job Scheduling Flexibility:

• Configured jobs to run at different intervals (daily, weekly, monthly) based on business requirements, using cron expressions for scheduling flexibility.

7) Testing and Optimization:

• Conducted testing of scheduled batch jobs to ensure timely and correct execution, validating data integrity across payment and settlement processes.
• Optimized job execution times and resource usage to reduce system load during peak hours.

8) Collaboration:

• Worked closely with other teams to align batch job schedules with overall system processes and external dependencies.
