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
What IPv6 Solves
IPv6 is the Internet Protocol designed to replace IPv4 and its limited address space. It provides a vastly larger addressing model, efficient autoconfiguration and native support for modern network growth. Companies use it for public services, internal networks, connected devices, cloud workloads and carrier infrastructure.
Addressing And Routing
IPv6 uses hexadecimal addresses, prefix delegation, SLAAC and DHCPv6 to assign network identities. Strong specialists design addressing plans, configure route summarization and apply OSPFv3, BGP or IS-IS where the environment requires it. They also account for DNS, reverse DNS, multicast and IPv4 coexistence.
Ecosystem And Tooling
IPv6 work spans operating systems, firewalls, load balancers, routers, Kubernetes clusters and public cloud services. Useful tooling includes packet captures, route analysis, IP address management, network monitoring and security policy testing. Familiarity with Linux, Windows Server, DNS, DHCP, automation and infrastructure as code often matters.
Typical Project Work
- Audit IPv4 networks and identify IPv6 readiness gaps
- Create dual-stack or IPv6-only migration plans
- Configure routing, firewall rules, DNS and address allocation
- Validate cloud, data-centre and Kubernetes connectivity
- Test applications, monitoring and security controls
In Germany, specialists may support manufacturing, telecommunications, public services, research and hosting environments. Remote delivery works well for design, configuration review and testing, while on-site access can help with physical network changes.
When Companies Need Help
Companies bring in freelance expertise when a provider, customer or public network requires IPv6 support, or when an infrastructure refresh exposes address and routing limits. They also need support during acquisitions, cloud migrations, data-centre moves and security reviews. Clear goals, current diagrams and access to test environments make the work more efficient.
What Good Specialists Deliver
- A documented address and routing plan
- Tested firewall, DNS and monitoring configurations
- A migration sequence with rollback options
- Evidence from functional, performance and security tests
The strongest professionals understand protocol details and operational risk. They explain trade-offs between dual stack, translation and IPv6-only designs, communicate clearly with network and application teams, and leave behind usable documentation and repeatable automation.
Frequently asked questions
The facts hiring teams ask for most often when it comes to IPv6.
Companies use IPv6 for public websites, cloud services, mobile and carrier networks, connected devices, research systems and expanding internal infrastructure. It provides a larger address space and supports network growth without depending entirely on address translation.
IPv6 offers a much larger address space and built-in mechanisms such as SLAAC and neighbour discovery, while IPv4 has the broader legacy footprint. Many organisations use dual stack during migration, although translation technologies or an IPv6-only design may suit particular environments.
A strong IPv6 freelancer should understand routing protocols, DNS, DHCPv6, firewalls, load balancers and network monitoring. Linux or Windows administration, cloud networking, Kubernetes, automation and security testing are also valuable for end-to-end delivery.
The right level of IPv6 experience depends on scope, risk and the number of network domains involved. An expert handling a small service rollout needs strong protocol and testing skills, while a large dual-stack migration calls for planning, change management and experience across infrastructure and applications.
Yes, much of an IPv6 project can be delivered remotely, including audits, design, configuration review, automation and test planning. On-site work may still be useful for physical network changes or restricted environments in German organisations, so agree on access, working language and maintenance windows early.
IPv6 dual stack is often practical when customers, applications or network devices still require IPv4. An IPv6-only approach can reduce legacy complexity in controlled environments, but it may need translation services and careful validation of every dependency.
Ask an IPv6 specialist to explain the addressing plan, routing decisions, security model and migration risks in clear terms. Review test evidence for DNS, applications, monitoring, failover and firewall behaviour, and check that diagrams, configurations and rollback steps are complete.
With IPv6, security policies must cover the protocol explicitly rather than assuming IPv4 controls will apply automatically. Professionals should review firewall rules, neighbour discovery, route advertisements, exposed services, logging and monitoring, while avoiding the mistaken belief that a large address space provides security by itself.
The average hourly rate of freelancers in Germany who have used IPv6 in their recent projects is 106 €, which corresponds to a daily rate of about 846 € based on an 8-hour working day.
Of the freelancers in Germany who have used IPv6 in their recent projects, 68% hold at least a Bachelor's degree and 40% hold at least a Master's degree.
On average, freelancers in Germany who have used IPv6 in their recent projects have 21 years of professional experience, with a single engagement typically lasting around 2.1 years.
