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
Infrastructure as Code explained
Infrastructure as Code, often called IaC, manages servers, networks, permissions and cloud services through version-controlled configuration files. Instead of creating environments manually, teams define the desired state and apply repeatable changes. This makes infrastructure easier to review, reproduce and restore across development, testing and production.
What it delivers
IaC specialists turn infrastructure requirements into maintainable, automated systems. Typical deliverables include:
- Reusable modules for cloud accounts, networks and Kubernetes clusters
- Environment definitions for development, staging and production
- Automated provisioning, updates and controlled teardown
- Documentation, ownership rules and change workflows
Tools and ecosystem
Terraform remains widely used for multi-cloud provisioning, while OpenTofu provides an open-source alternative with compatible configuration patterns. Pulumi lets teams define infrastructure with general-purpose languages, and Ansible handles configuration and orchestration. Strong specialists also work with cloud-native templates, Git, CI/CD pipelines, policy checks, secrets management and Kubernetes tooling.
When companies need help
Companies often bring in freelance expertise when infrastructure has grown faster than its operating model or when a cloud migration needs a safe foundation. Signs include repeated manual changes, inconsistent environments, unclear ownership and deployments that depend on individual knowledge. In Cologne, specialists may support local teams on site, remotely or in a blended setup, depending on security and collaboration needs.
Skills beyond provisioning
Effective IaC work connects infrastructure decisions with software delivery and operations. Professionals should understand networking, identity and access management, containers, observability, backup design and cloud security. They also need to structure repositories, review plans, protect state files and design workflows that allow teams to change infrastructure without losing control.
Choosing a strong specialist
Look for evidence of production systems rather than isolated configuration examples. A strong professional explains state management, dependency handling, drift detection, rollback limits and the risks of destructive changes. They use pull requests, automated validation and clear documentation, and they can adapt the design to the team’s cloud provider, compliance needs and delivery process.
Frequently asked questions
Key details about Infrastructure as Code, drawn from the questions we get asked most.
Infrastructure as Code is used to provision and manage cloud resources, networks, databases, permissions, virtual machines and Kubernetes environments through declarative or programmable configuration. It supports repeatable environments, automated delivery and auditable infrastructure changes.
Terraform and OpenTofu use declarative configuration and are commonly chosen for provisioning resources across cloud providers. Pulumi uses familiar programming languages, while Ansible is often stronger for configuration and orchestration after resources exist. The right choice depends on team skills, provider coverage, governance and existing code.
A strong Infrastructure as Code specialist usually understands cloud networking, identity and access management, Linux, containers, Kubernetes and CI/CD. Knowledge of secrets handling, observability, security controls and cost-aware architecture is also valuable because infrastructure changes affect the full delivery system.
The needed IaC experience depends on the scope and risk of the environment. A small internal setup may need help with modules and pipelines, while a multi-account or regulated system requires proven skills in state management, access controls, migration planning and recovery procedures.
Yes, Infrastructure as Code work is often well suited to remote collaboration because repositories, plans and pipeline results can be reviewed online. Cologne companies should agree on language, working hours, access procedures and expectations for on-site workshops before the engagement begins.
A good Infrastructure as Code implementation is readable, modular and safely repeatable. Review how it handles state, secrets, dependencies, drift, testing, approvals and destructive operations. Clear documentation and a practical recovery process matter as much as successfully creating resources.
IaC is preferable when environments must be reproduced, reviewed or changed regularly, or when several people manage the same cloud estate. Manual setup can be acceptable for a temporary experiment, but it becomes risky when configuration needs to be consistent across teams or environments.
Before starting an IaC engagement, clarify the cloud providers, existing repositories, state ownership, deployment process, access boundaries and definition of success. Freelancers should also understand whether they are improving an existing Terraform or OpenTofu codebase, introducing Pulumi or Ansible, or designing the operating model from the beginning.
