Jens R.
Last position:
Platform Architect & Senior Developer at Direct client, industrial measurement technology, medium-sized company
- Technical leadership across hardware, firmware, and software teams; scope: hardware/firmware team (4 people) and leadership group (5 people)
- Consolidated and documented a product family that had grown over more than 15 years and aligned it with CRA compliance — from the bare-metal I/O module to the cloud interface.
- Provided the most important customer product with the essential requirements and architecture documentation within two months — for a firmware landscape that had grown over more than 15 years. It now supports the customer’s modernization strategy.
- Established a monthly reporting line to the supervisory board and executive board within three months: nine meetings since 12/2025. The report itself is versioned and built from the CI pipeline; it is based on automatically collected activity and release data instead of assessments.
- Built a container-based CI/CD infrastructure from scratch: cross-compilation, host tests, and documentation builds in one continuous pipeline.
- Introduced declarative QA gates for DevOps and development artifacts — from the start using lefthook instead of pre-commit, executed in a dedicated container image.
Technologies used: arc42, req42, tpo42, docToolchain, PlantUML, ArchiMate, C4 model, ADR, C, C++ (GTest), CMake, Bare Metal (ARM Cortex-M3/M7), OCI containers, Jenkins, lefthook, Prometheus, Grafana, SBOM, CRA, OPC, SCADA, PLC integration, IPv6 migration, Zero Trust, Sociocracy 3.0, Cynefin

About the technology
What Helm does
Helm is a package manager for Kubernetes. It groups manifests, configuration and release logic into reusable Charts, so teams can install and update applications consistently. Helm supports repeatable deployments across development, staging and production clusters.
Charts and templates
A Chart defines Kubernetes resources through templates and values. Strong Chart structures separate application settings from deployment logic, support safe defaults and make environment-specific changes explicit. Professionals also manage dependencies, Chart repositories and versioning for reliable distribution.
Delivery workflows
Helm fits into continuous delivery pipelines and Git-based release processes. It can install, upgrade, roll back and inspect releases while preserving a clear deployment history. Experts connect Helm with tools such as Argo CD, Flux, GitHub Actions, GitLab CI and other Kubernetes automation systems.
Where it is used
Companies use Helm where Kubernetes applications must be deployed repeatedly across clusters or environments.
- Package microservices and supporting infrastructure
- Standardize releases for internal development teams
- Configure observability, ingress and storage components
- Operate multi-environment application delivery
- Publish reusable Charts for platform teams
When specialists help
Freelance expertise is useful during a Kubernetes migration, a Chart redesign or a release-process overhaul. Companies in Cologne may need specialists who can work remotely or on site and collaborate clearly with German- and English-speaking teams. They also help resolve failed upgrades, configuration drift and complex dependency issues.
What quality looks like
A strong Helm professional understands Kubernetes objects, namespaces, security contexts, networking, storage and container images rather than treating Charts as isolated templates. They test rendered manifests, validate values, document upgrade paths and consider rollback behavior. Good work leaves teams with maintainable Charts, predictable releases and clear ownership.
Frequently asked questions
Not sure where to start with Helm? These answers cover the essentials.
Helm is used to package and deploy Kubernetes applications as reusable Charts. It helps teams manage configuration, dependencies, upgrades and rollbacks across multiple environments.
Helm uses templated Charts with configurable values, while Kustomize applies overlays to largely declarative YAML. The better choice depends on the team’s configuration model, reuse needs and delivery workflow; many Kubernetes environments use both.
A strong Helm specialist should also understand Kubernetes, container images, YAML, networking, ingress, secrets and persistent storage. Experience with Git, CI/CD and delivery tools such as Argo CD or Flux is valuable for production work.
The right level of Helm experience depends on the work. A small Chart adjustment may need focused configuration knowledge, while a platform migration or shared Chart library requires strong Kubernetes design, release management and troubleshooting skills.
Yes, Helm work is well suited to remote collaboration when repositories, cluster access and delivery responsibilities are clearly organized. On-site work in Cologne can still help when teams are redesigning platform processes or coordinating closely with internal operations groups.
Helm is a good fit for packaging and releasing Kubernetes resources through repeatable templates. An Operator is more appropriate when software needs continuous, domain-specific reconciliation after deployment; the two approaches can also complement each other.
Review how Helm Charts handle values, dependencies, secrets, naming, validation and upgrades. A quality Chart produces predictable manifests, supports safe rollback, includes meaningful documentation and is tested against the Kubernetes environments where it will run.
A Helm professional may deliver new or refactored Charts, values files, dependency definitions, CI/CD integration and release documentation. They can also create testing and validation steps that make deployments easier to review and operate.
