Root Cause: Sahil
Recreating the internet's worst outages. Live. On my laptop.
Backend by day, blast radius by night.
By day, I build backend systems on AWS—microservices, APIs, observability, and the infrastructure that keeps applications running.
By night, I reconstruct infamous engineering failures to uncover the real root cause, then build deliberately over-engineered (and mostly useless) software just to see what breaks.
If you've ever wondered how billion-dollar outages happen—or why simple systems become beautifully complicated—you're in the right place.
Fresh incidents.
I Built a Kubernetes Cluster to Run a Todo App (And Regretted Everything)
Three nodes, a service mesh, and a horizontal pod autoscaler, all in service of tracking whether I bought milk.

One engineer, one typo in a debugging playbook, and enough removed capacity to take down a chunk of the internet. I rebuilt it at toy scale to see the failure for myself.
