Site Reliability Engineer at Nexamatic who migrated 120 repositories and operates production AKS clusters.

At Nexamatic, I designed and operated an Azure landing zone and production AKS clusters for life sciences clients. I migrated about 120 repositories to GitHub Enterprise and converted classic release pipelines into GitHub Actions workflows and reusable Azure DevOps YAML templates.

I built SRE practices around SLIs, SLOs, error budgets and runbooks, helping reduce MTTR by about 35%. Earlier, I supported Azure infrastructure and migrations at Kumaran Systems, UST Global and Cognizant, and administered Linux and Windows systems at Anewa Engineering Pvt. Ltd.
