What I'm looking for

I am looking for a role that fosters innovation and collaboration, with opportunities for growth and impactful projects.

With over 10 years of experience as a DevOps Engineer and Site Reliability Engineer, I specialize in building and managing highly available, scalable, and secure cloud-based infrastructures. My expertise in CI/CD pipelines, automation, and monitoring tools allows me to drive continuous integration and delivery across various environments. I excel in container orchestration using Docker and Kubernetes, and have hands-on experience with configuration management tools like Terraform and Ansible.

I am committed to improving system performance, reducing downtime, and enhancing security posture. By fostering strong collaboration between development, operations, and security teams, I ensure smooth deployment cycles and successful product releases. My focus on operational excellence has led to significant cost efficiencies and improved service quality in dynamic environments.
