About

Professional summary

I am a Senior DevOps Engineer and Systems Administrator with more than three years of hands-on experience supporting enterprise IT operations in a regulated banking environment. I focus on maintaining reliable, secure, and highly available systems across production and disaster recovery environments.

I administer Linux and Windows Server environments, including RHEL, Oracle Linux, Windows Server, JBoss EAP, and Tomcat-hosted applications. My work includes server configuration, patching, user administration, application deployment, service management, and operational troubleshooting.

I support enterprise application integrations and core banking operations, including RESTful and SOAP APIs, Temenos T24, Spring Boot services, JSON-based data flows, and JBase scripting. I have contributed to API integrations, AML compliance platforms, electronic tax payment integrations, automated risk assessment services, and core banking data migration initiatives.

I use Bash scripting, cron scheduling, Jenkins, GitHub Actions, and Git to support automation and CI/CD processes. I also perform log analysis, health checks, alerting, incident response, and technical documentation to improve operational consistency and reduce manual effort.

I bring AWS-certified cloud knowledge in Solutions Architecture, Development, DevOps, and Well-Architected design to on-premise and hybrid infrastructure. I am experienced in supporting security controls, Oracle database operations, backup monitoring, disaster recovery readiness, and cross-functional collaboration between development, operations, and business teams.
