About Gayathri Challa

I am a Cloud Engineer with 5+ years of experience designing, automating, and operating large-scale cloud infrastructure across AWS. I specialize in infrastructure automation, multi-region cloud deployments, cloud security controls, and service reliability engineering.At Amazon Web Services (AWS Lambda), I work on global AWS service infrastructure, where I automate new region builds, implement deployment safety mechanisms, improve operational resilience, and support mission-critical services through on-call ownership and incident response. My work focuses on building scalable, secure, and highly available cloud platforms using AWS CloudFormation, Python automation, monitoring, and cloud networking.Previously at Tech Mahindra, I designed and implemented Azure cloud infrastructure and DevOps solutions for enterprise applications - including CI/CD pipelines, containerized workloads on AKS, hybrid cloud networking, identity and access management, and cloud security architectures.I enjoy solving complex infrastructure challenges, improving automation, and building reliable cloud systems that scale globally.
