It tries to remediate incidents with configurable, action oriented workflows before escalating to oncall engineers. Countless engineering hours saved.
● Built a CLI tool to zero downtime kubernetes cluster upgrades, Istio mesh upgrades across clouds i.e GKE, EKS.
o 5x team productivity increase
o 500+ hours saved per year, Upgrade time reduced from weeks to days.
● Traceable packages signing
o Read: https://docs.traceable.ai/docs/code-signing, signing ensures packages produced by Traceable AI are publicly verifiable if they were altered any way after build.
