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.

- 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.

About the technology
What Grafana does
Grafana is an open-source observability and visualization platform for turning operational data into clear, interactive dashboards. It queries metrics, logs, traces and other time-series data without requiring teams to move everything into one database. Companies use it to monitor applications, infrastructure, business processes and connected devices.
Core data sources
Grafana connects to a broad ecosystem of data sources, including Prometheus, Loki, Elasticsearch, InfluxDB, Graphite, PostgreSQL and cloud monitoring services. Strong specialists configure queries, variables, transformations, alert rules and reusable dashboard layouts. They also understand how each source handles retention, labels, dimensions and access control.
Typical deliverables
- Executive and operational dashboards for services, platforms and production teams
- Prometheus and Loki integrations for metrics and logs
- Alerting rules, notification policies and incident views
- Provisioned dashboards managed through files, APIs or Terraform
- Grafana Cloud or self-hosted deployments with secure user access
When expertise matters
Companies bring in freelance Grafana expertise when dashboards have become inconsistent, alerts create noise or teams cannot connect signals across their stack. Specialists can establish observability standards during a migration, Kubernetes rollout or reliability initiative. In Cologne, they may support local product, media, logistics and industrial teams through on-site workshops or remote delivery.
Skills around Grafana
Effective work with Grafana includes more than panel design. Professionals often bring experience with PromQL, LogQL, SQL, OpenTelemetry, Kubernetes, Docker, Linux, Terraform and CI/CD workflows. They should be able to map technical signals to useful service indicators, document ownership and integrate dashboards into existing incident and access processes.
Choosing a strong specialist
Look for someone who can explain why a dashboard or alert exists, not only how it was configured. Review examples of readable layouts, meaningful thresholds, query performance and permission design. A capable freelancer asks about the audience, data quality and operational response, then leaves behind maintainable dashboards, tested alerting and clear documentation.
Frequently asked questions
Not sure where to start with Grafana? These answers cover the essentials.
Grafana is used to visualize metrics, logs, traces and other data in interactive dashboards. Companies use it for infrastructure monitoring, application observability, alerting, capacity planning and operational reporting.
Grafana is designed to work across many data sources, while Kibana is closely associated with the Elastic Stack. Grafana can be the better choice when a company needs one visualization and alerting layer for Prometheus, Loki, SQL databases and cloud services.
A strong Grafana specialist often works with Prometheus, Loki, PromQL, LogQL, OpenTelemetry and Kubernetes. Knowledge of Terraform, CI/CD, cloud monitoring, Linux and access management is also valuable for production-ready delivery.
The right level depends on the scope. A simple dashboard may need focused configuration skills, while an observability program requires a Grafana professional who understands data modeling, alert design, security, performance and operational workflows.
Grafana supports many data sources beyond Prometheus, including Loki, Elasticsearch, InfluxDB, Graphite, PostgreSQL and cloud monitoring services. The best source depends on the data type, query needs, retention model and existing architecture.
Yes. Grafana projects are often suitable for remote collaboration because configuration, dashboards and infrastructure code can be reviewed online. For Cologne teams, occasional on-site workshops can still help align stakeholders on alert ownership, dashboard standards and incident processes.
Ask a Grafana freelancer to explain the purpose of each dashboard, query and alert. Quality work uses clear naming, useful thresholds, efficient queries, appropriate permissions and documentation that another specialist can maintain.
A Grafana freelancer should be comfortable with the company's cloud, infrastructure and security practices, as well as its preferred language for workshops and documentation. Clarify access requirements, data sensitivity, remote availability and whether the engagement includes handover to the internal team.
