What I'm looking for

I am seeking a role that fosters innovation, collaboration, and growth opportunities in database management and DevOps.

I am a Senior PostgreSQL Database Engineer with over 12 years of IT experience, specializing in database administration and DevOps integration. My expertise lies in performance tuning, high availability, and implementing robust backup and recovery strategies. I excel in deploying secure PostgreSQL environments across hybrid cloud and on-premises infrastructures.

Throughout my career, I have automated CI/CD pipelines using tools like Ansible and Jenkins, significantly reducing manual efforts and enhancing deployment cycles. My role at Wells Fargo involved administering multiple PostgreSQL clusters, ensuring data integrity for mission-critical applications, and collaborating with cross-functional teams to integrate database changes into Agile workflows.

My commitment to continuous improvement and proactive monitoring has led to a 30% reduction in database-related downtime. I am passionate about leveraging my skills to drive efficiency and reliability in database management, and I look forward to contributing to innovative projects in a dynamic environment.
