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
Monitoring foundations
Prometheus is an open-source monitoring and alerting system for time-series data. It collects metrics by scraping HTTP endpoints, stores them with labels, and supports PromQL for analysis. Companies use it to observe applications, services, containers and infrastructure.
Cloud-native observability
Prometheus is closely associated with Kubernetes, where it monitors workloads, nodes and control-plane components. It also fits Docker, OpenShift and service-oriented environments, often alongside Grafana for dashboards and Alertmanager for notifications. Exporters extend coverage to databases, operating systems, message queues and network services.
Practical deliverables
- Design metric names, labels and scrape configurations
- Build PromQL queries, recording rules and alerting rules
- Create Grafana dashboards for teams and operations
- Connect Alertmanager to email, chat or incident tools
- Integrate exporters and service discovery into existing systems
Strong delivery starts with useful signals rather than collecting everything. Experts define actionable alerts, control label cardinality, and document the meaning and ownership of each metric.
When expertise matters
Companies bring in freelance Prometheus expertise when monitoring is inconsistent, alerts are noisy, or a Kubernetes environment has outgrown basic checks. A specialist can establish observability during a migration, improve an existing setup, or prepare a monitoring design for production workloads. In Cologne, local teams can combine on-site workshops with remote implementation when that suits their delivery model.
Skills around Prometheus
Useful adjacent skills include Kubernetes operations, Linux, containers, Grafana, Alertmanager and infrastructure as code with Terraform or Ansible. Professionals may also work with OpenTelemetry, cloud monitoring services and long-term metric storage such as Thanos or Cortex. Knowledge of application instrumentation in languages such as Java, Go or Python helps connect business-relevant signals to system metrics.
What strong specialists show
Look for experience turning service objectives into clear metrics, dashboards and alerts. Strong professionals understand pull-based monitoring, federation, service discovery, metric types, retention and scaling limits. They can explain trade-offs between Prometheus, hosted monitoring and OpenTelemetry, test alert behaviour, and leave behind configurations that teams can operate confidently.
Frequently asked questions
Everything clients usually want to know about Prometheus, in one place.
Prometheus collects and stores time-series metrics from applications, services and infrastructure. Teams use PromQL to investigate behaviour and Alertmanager to route notifications when defined conditions occur.
Prometheus gives teams control over collection, queries and alert rules, which suits cloud-native environments and custom instrumentation. Hosted services can reduce operational work and offer simpler long-term storage, so the right choice depends on scale, compliance needs and internal capability.
Prometheus is primarily a metrics collection, storage and alerting system, while Grafana visualises data from Prometheus and many other sources. They are often used together, but Grafana does not replace metric collection or alert evaluation by itself.
A strong Prometheus freelancer often understands Kubernetes, Linux, containers, Grafana, Alertmanager and infrastructure as code. Experience with OpenTelemetry, exporters and application instrumentation is also valuable when monitoring spans several teams or runtimes.
Prometheus projects need practical experience with the relevant system, not just familiarity with dashboards. A professional should be able to design labels and scrape jobs, write reliable PromQL, control alert noise and explain retention and scaling choices.
Yes, Prometheus configuration, dashboard work and troubleshooting are usually well suited to remote collaboration. On-site sessions in Cologne can still help with architecture workshops, access processes and knowledge transfer, while clear documentation keeps distributed work effective.
Ask a Prometheus specialist to explain a monitoring design using real service objectives, not only screenshots. Good answers cover metric semantics, label cardinality, alert ownership, failure testing, security and how the team will operate the result after handover.
Yes, Prometheus can scrape metrics from virtual machines, bare-metal systems, databases, network services and custom applications. Exporters and compatible endpoints make it useful beyond Kubernetes, while service discovery helps maintain targets as environments change.
