About Shamsher Khan
15+ years breaking and fixing production systems.
Currently managing 8 Kubernetes clusters
for Fortune 500 pharmaceutical and retail clients
at GlobalLogic, a Hitachi company.
I built OpsCart because most Kubernetes content teaches you how things should work. I write about how they actually work — at 2am, under pressure, with real consequences. Every article, lab, and guide here comes from production incidents, not documentation.
