About

Author

Oliver Karstoft

As a Tech Lead within the Developer Platform space, I specialize in building robust internal ecosystems that empower engineering teams to ship high-quality software at scale. With a foundation as a System Engineer in Engineering Services, I combine deep technical expertise in GCP and Kubernetes with a strategic focus on Platform Engineering.

I lead the design of internal developer platforms (IDP) and tooling in Golang, shifting the focus from manual infrastructure management to a self-service model that reduces cognitive load. I am a strong advocate for developer enablement, dedicated to refining deployment flows and bridging the gap between complex cloud-native architecture and developer productivity through education and automation.

Open-Source Contributions

Project	Link	Description
Gatekeeper - Helm Chart	Merge namespace exemption labels to fix GKE recommendation	Gatekeeper is a policy controller for Kubernetes that allows you to enforce policies on your cluster resources. This contribution fixes an issue where GKE recommended labels for namespace exemptions were not being handled correctly.
HashiCorp Golang Module - `go-version`	Add support for prefix of any character	The `go-version` module is a Go library for parsing and comparing semantic versions. This contribution adds support for version strings that have a prefix of any character, which is useful for handling versions that may have a non-semantic prefix. Many repositories containing an application and a Helm Chart use a prefix for the chart version, such as `1.0.0` for the application and `chart-1.0.0` for the Helm Chart.
