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
Observability dashboards
Grafana is an open-source platform for querying, visualizing and monitoring data from many sources. Companies use it to turn metrics, logs and traces into dashboards that help teams understand application health, infrastructure behavior and business-critical services.
Data sources
Grafana connects to observability and time-series systems such as Prometheus, Loki, InfluxDB, Elasticsearch, Graphite and cloud monitoring services. Strong specialists select suitable data sources, design efficient queries and structure variables, annotations and transformations so dashboards stay useful as systems change.
Monitoring workflows
- Create service, infrastructure and business dashboards
- Configure alerts, contact points and notification policies
- Explore logs, metrics and traces across connected systems
- Establish reusable dashboard and panel conventions
These workflows support incident response, capacity planning and ongoing service improvement. Grafana can also unify views across cloud, container and distributed application environments.
Ecosystem skills
Effective Grafana work often includes Prometheus and PromQL, Loki and LogQL, OpenTelemetry, Kubernetes, Docker and Terraform. Specialists may also work with Grafana Alerting, Grafana Alloy, provisioning files, access controls and APIs. Familiarity with Linux, cloud services and CI/CD helps connect observability to daily operations.
When to engage experts
Companies bring in freelance Grafana expertise when existing dashboards are inconsistent, alerts create noise or teams lack a clear view of production behavior. It is also valuable during a migration, a Kubernetes rollout, an observability redesign or the handover of monitoring from one team to another. In Cologne, remote collaboration is common, while on-site workshops can help align operations and product teams.
Quality indicators
Strong professionals begin with the questions teams need monitoring to answer rather than filling screens with charts. They use meaningful labels, readable layouts, useful thresholds and alerts tied to clear actions. They document data sources and ownership, test alert routes, manage dashboards as code where appropriate and explain trade-offs to both technical and non-technical stakeholders.
Frequently asked questions
Not sure where to start with Grafana? These answers cover the essentials.
Grafana is used to explore, visualize and monitor data from metrics, logs, traces and other sources. Companies use it for operational dashboards, alerting, incident response, capacity planning and service health reporting.
Grafana is often compared with tools such as Kibana, Datadog, New Relic and native cloud monitoring consoles. Its strength is flexible visualization across many data sources, while the best choice depends on query needs, alerting, hosting preferences and the existing observability stack.
A strong Grafana specialist commonly works with Prometheus, PromQL, Loki, LogQL, OpenTelemetry and Kubernetes. Skills in cloud monitoring, Terraform, Docker, Linux, APIs and incident management help turn dashboards into a dependable operational workflow.
The right Grafana experience depends on the scope. A dashboard refresh needs strong visualization and query skills, while a monitoring platform or alerting redesign calls for deeper knowledge of data collection, access control, automation and production operations.
Yes, Grafana work is well suited to remote collaboration because dashboards, queries and configuration can be reviewed in shared repositories and environments. For teams in Cologne, occasional on-site sessions can still help with discovery, incident reviews and agreement on monitoring standards.
Ask a Grafana freelancer to explain how they choose dashboard signals, reduce alert noise and validate data quality. Review examples of readable dashboards, documentation and alert runbooks, then discuss how they would work with your existing data sources and stakeholders.
Grafana does not usually replace a metrics, logging or tracing backend. It provides a visualization and alerting layer that can query systems such as Prometheus, Loki, Elasticsearch or cloud services, so the underlying storage and collection design still matter.
A Grafana expert can deliver dashboards, data-source integrations, alert rules, notification policies, provisioning files and access configurations. They may also provide dashboard-as-code workflows, documentation, runbooks and guidance for maintaining observability after the engagement.
