I have extensive experience with Oracle E-Business Suite, having worked with modules such as Financials, Supply Chain Management, and Human Capital Management. My role involved configuring, customizing, and integrating these modules to meet business requirements. I also have experience in troubleshooting and resolving issues related to data integrity, performance, and user access.

I approach system integration by first understanding the business processes and data flows between Oracle applications and third-party systems. I then design integration solutions using Oracle Integration Cloud Service (ICS) or Oracle SOA Suite, ensuring data consistency and real-time synchronization. I also perform thorough testing to validate the integration and ensure it meets all business requirements.

I ensure data security by implementing role-based access controls, encrypting sensitive data, and regularly auditing user activities. I also stay updated on industry regulations and ensure that our Oracle applications comply with standards such as GDPR and HIPAA. Additionally, I conduct regular security assessments and vulnerability scans to identify and mitigate potential risks.

I handle performance tuning by analyzing system logs, database statistics, and application usage patterns to identify bottlenecks. I then optimize SQL queries, adjust database parameters, and fine-tune application configurations to improve performance. I also implement caching mechanisms and load balancing strategies to ensure the application runs smoothly under high load conditions.

One challenging project involved migrating an Oracle EBS instance to a new cloud environment while ensuring minimal downtime. I overcame the challenges by meticulously planning the migration, including data validation, system testing, and a phased rollout. I also coordinated closely with the IT and business teams to ensure a smooth transition, resulting in a successful migration with no data loss or business disruption.
