Hello, I'm

Mayur Chavhan

Senior |

I'm a Senior DevOps Engineer, SRE and Platform Engineer with 10 years of hands-on experience running cloud and on-prem infrastructure. I manage 2,000+ servers (including 500+ production systems) across AWS, Kubernetes, Terraform, GitLab CI/CD and observability stacks. I hold the AWS Solutions Architect and RHCE certifications, and I've built zero-touch patching and AI-driven automation tools that keep systems secure, compliant and reliable.

I'm a Senior DevOps Engineer, SRE and Platform Engineer with 10 years of experience running cloud and on-prem infrastructure. I've managed 2,000+ servers (500+ production) across AWS, Azure and hybrid environments, and I design the automation, observability and security layers that keep them reliable.

My day-to-day work spans AWS, Kubernetes, Terraform, Ansible, GitLab CI/CD, Docker and GitOps. I'm also AWS Certified Solutions Architect - Associate and Red Hat Certified Engineer (RHCE), with deep Linux administration, security hardening and PCI-DSS experience.

At FIS I resolved 320+ vulnerabilities and built VRT AppVault, a zero-touch patching tool that serves 500+ servers without direct login. At MGT-Commerce I kept 300+ e-commerce clients online through peak traffic events. I like infrastructure that is observable, recoverable and boring in the best way: it just works.
