About Jakub Ciolek

I’m Jakub Ciolek, a Staff Cloud Security Engineer at AlphaSense. Before moving fully into security, I spent about a decade in cloud and platform engineering.

Jakub Ciolek portrait

short bio

My work focuses on cloud security, Go internals, and low-level failures that break higher-level guarantees.

I’ve reported vulnerabilities and helped drive fixes in Go, Helm, Argo CD, Spinnaker, and other widely used software, and I’ve spoken about fuzzing and bug finding at KubeCon and KCD Helsinki.

this site

This site is where I write about compilers, Go internals, cloud-native security, and systems that behave differently under stress than they do on paper.

topics

Cloud security. Go internals. Compilers. Fuzzing. Systems engineering.
