About
With over 7 years of extensive experience in Cloud and DevOps Engineering, I, Mohd Ahmed Ahsanullah, have honed my skills in AWS, Azure, Terraform, Ansible, and Jenkins. My technical acumen spans Groovy scripting for Chef Automation, developing user interfaces with Next.js and React, and managing complex Azure and AWS infrastructures. In my recent role as a Senior DevOps Engineer at Charter Communications, I led projects that significantly reduced post-production bugs and system downtime through effective CI/CD pipeline management and proactive monitoring tools. I also introduced Infrastructure-as-Code (IaC) using Terraform, optimizing resource utilization and achieving substantial cost reductions. My expertise includes migrating enterprise applications to Azure, automating infrastructure on AWS, and containerizing deployments with Docker and Kubernetes. I am adept at scripting with Python and PowerShell, managing VMware environments, and leveraging a wide range of cloud services and tools. Throughout my career, I have demonstrated strong analytical and problem-solving skills, coupled with excellent communication and collaboration abilities. I have a solid foundation in Unix/Linux environments, SQL databases, and version control systems, ensuring efficient and reliable DevOps processes. I hold a Bachelor's degree in Science from NED University, and I am proficient in various technical skills, including cloud platforms (Microsoft Azure, AWS), infrastructure tools (CloudFormation, Terraform), CI/CD tools (Jenkins, Ansible), and container platforms (Docker, Kubernetes). My professional journey includes impactful roles at CNA Financial, Express Scripts, and MetLife, where I consistently contributed to enhancing system performance, scalability, and cost-efficiency. I am committed to leveraging my skills and experience to drive innovative solutions and deliver exceptional results in any challenging DevOps environment.
