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.

About the technology
Metrics and monitoring
Prometheus is an open-source monitoring and alerting system for collecting time-series metrics. It scrapes HTTP endpoints, stores samples with labels and lets teams query operational data with PromQL. Companies use it to understand service health, capacity, latency and failures across distributed systems.
Prometheus ecosystem
A complete setup often combines Prometheus with exporters, Grafana and Alertmanager. Node Exporter exposes host metrics, while application libraries instrument services written in languages such as Java, Go, Python or JavaScript. Kubernetes integrations discover workloads and scrape targets automatically, and long-term storage can extend the native time-series model.
Typical delivery work
- Define metric names, labels and recording rules
- Configure scrape jobs, service discovery and relabeling
- Build PromQL queries, Grafana dashboards and alert rules
- Connect Alertmanager to reliable notification routes
- Tune retention, cardinality and storage for production
Specialists may also establish monitoring standards, document runbooks and connect Prometheus data with incident response processes.
When companies need specialists
Freelance expertise helps when a team is moving services into Kubernetes, replacing fragmented monitoring or investigating noisy alerts. It is also valuable during cloud migrations, platform consolidation and the rollout of service-level objectives. Cologne companies running software, logistics, media or industrial systems may need local workshops combined with remote delivery.
Skills that matter
Strong professionals understand metric design as well as the systems behind the metrics. They can work with Linux, containers, Kubernetes, Docker, Helm, Grafana, Alertmanager and infrastructure-as-code tools such as Terraform. They know how application instrumentation, exporters and service discovery affect query quality and operational cost.
What good work looks like
Effective Prometheus implementations produce useful signals rather than a large volume of charts. A capable specialist controls label cardinality, protects the monitoring system, tests alert expressions and explains what each alert requires someone to do. They distinguish symptoms from causes and connect dashboards to clear ownership, escalation and incident procedures.
A strong delivery includes maintainable configuration, readable PromQL, documented assumptions and dashboards that support real decisions. Professionals working with teams in Cologne should also make remote and on-site collaboration clear, communicate in the required language and adapt their approach to existing security and operations practices.
Frequently asked questions
Everything clients usually want to know about Prometheus, in one place.
Prometheus collects and queries time-series metrics from applications, infrastructure and services. Companies use it for dashboards, alerting, capacity planning and service-level monitoring, often with Grafana and Alertmanager.
Prometheus is primarily a metrics collection, storage and query system with its own pull-based model and PromQL. Grafana focuses on visualization, InfluxDB offers an alternative time-series database approach, and Datadog provides a managed observability service with broader commercial features.
A strong Prometheus specialist often works with Grafana, Alertmanager, Kubernetes, Helm, Docker and Terraform. Application instrumentation, Linux operations, cloud services, service discovery and incident response are also important when monitoring must work in production.
The right level depends on the scope. A small dashboard or exporter task may need focused Prometheus knowledge, while a production observability program calls for someone who understands metric architecture, PromQL, alert design, scaling and operational ownership.
Yes. Prometheus work is often well suited to remote collaboration because configuration, queries and dashboards can be reviewed online. On-site workshops in Cologne can still help with architecture decisions, access processes and incident-readiness discussions, while language expectations should be agreed early.
Ask the specialist to explain label choices, scrape behavior, recording rules and alert conditions in practical terms. High-quality Prometheus work includes tested PromQL, controlled cardinality, useful runbooks and alerts that lead to clear action rather than noise.
Common problems include unbounded labels, excessive scrape intervals, alerts without ownership and dashboards that show symptoms without context. Experienced Prometheus professionals also check retention, target discovery, access controls and the effect of monitoring workloads on the monitored systems.
Prometheus is a strong fit for infrastructure, cloud-native services and applications that expose metrics endpoints. Teams may consider another system when they need fully managed operations, a different storage model, deep vendor-specific telemetry or a unified commercial observability suite.
The average hourly rate of freelancers in Cologne, Germany who have used Prometheus in their recent projects is 108 €, which corresponds to a daily rate of about 861 € based on an 8-hour working day.
