    DB into cross‑domain systems.
  • Supporting CI/CD pipelines using Jenkins, Git, and Artifactory.
  • Evaluating and recommending technology components, including software, hardware, networking, and database management capabilities.
• Monitoring & Automation:
  • Implementing automated database testing using tools like Selenium or Robot Framework.
  • Utilizing tools like App Dynamics or other monitoring platforms for real‑time database performance oversight.
• AWS Cloud Expertise:
