I have proven expertise in designing, deploying, and managing robust cloud infrastructures. I specialize in building CI/CD pipelines, Infrastructure as Code (IaC) using Terraform and and ensuring high availability, scalability, and cost optimization for mission-critical systems.

Certified as an AWS Solutions Architect - Associate, I excel in Linux system administration, Docker, and Kubernetes, driving secure and efficient cloud solutions. Passionate about solving complex challenges, I continuously innovate to optimize cloud operations and advance technology adoption within organizations.
