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

Last position:
Technical Project Management at CHG Meridian AG
- CHG Meridian AG is a financial company focused on leasing in the areas of IT technology, logistics and medical technology and is regulated by BaFin. One part of the company is Return to Remarketing, where devices delivered to the technology center (notebooks, smartphones, tablets, etc.) are prepared for resale. The project I supported was responsible for enabling damage assessment of returned lease devices, documenting them visually in the form of pictures, enabling invoicing for the customer, and making the pictures available via the in-house customer platform. This was achieved through a combination of in-house development within the internal development department and the use of SaaS products. The second project was the transition of SaaS tendering software, purchased by the business unit, into the operations of the CHG IT department. Evaluation of security questions in relation to BaFin requirements, development of an authorization concept, implementation of single sign-on, documentation of the application in the CHG systems (CMDB, iKnow, etc.) and handover into operations.
Used technologies and methods: NIS2, DORA, agile software development, Scrum, Kanban, ServiceNow, SaaS, MS Teams, MS SharePoint, Active Directory, Entra ID, CMDB, incident management, change management, request management, service level agreement

About the technology
Secure network access
OpenVPN is an open-source virtual private network system for encrypted access between users, offices, data centres and cloud environments. It uses TLS for authentication and can operate over UDP or TCP, making it suitable for remote work, administration and protected connections across untrusted networks.
Core applications
Companies use OpenVPN to connect distributed environments without exposing internal services directly to the internet.
- Remote access for employees and external professionals
- Site-to-site links between offices, facilities and cloud networks
- Protected access to private applications and administration tools
- Segmented connections for suppliers, partners and operational teams
Ecosystem and tooling
OpenVPN commonly runs on Linux servers, virtual machines, network appliances and cloud instances. Strong expertise includes OpenVPN Access Server, community OpenVPN, certificate authorities, PKI, firewall rules, DNS, routing, identity providers and client profiles for Windows, macOS, Linux, Android and iOS.
When specialists help
Freelance specialists are useful when an existing VPN is unreliable, difficult to audit or unable to support a changing organisation. They can plan a migration, design network routes, establish certificate lifecycles, integrate authentication and document operations. In Germany, remote delivery is often practical, while site visits can help with office firewalls, industrial networks and regulated environments.
Reliable implementation
A sound OpenVPN setup starts with clear trust boundaries and least-privilege access. Professionals should understand cipher and TLS settings, certificate revocation, key protection, address pools, split tunnelling, logging and backup procedures. They also test failure scenarios instead of treating a successful connection as proof of a secure design.
Choosing the right expert
Look for specialists who can explain why UDP or TCP fits the use case, distinguish user access from network-to-network routing and show how access is removed when circumstances change. Relevant experience with Linux, firewalls, cloud networking, monitoring and incident response matters as much as creating a client configuration. Clear diagrams and operating instructions make the result maintainable after handover.
Frequently asked questions
Curious about OpenVPN? Here are the answers that come up again and again.
OpenVPN creates encrypted tunnels between users, offices, servers and cloud networks. Companies use it for remote access, site-to-site connectivity and controlled access to internal services.
OpenVPN has a mature ecosystem, broad client support and flexible TLS-based authentication. WireGuard is often simpler and faster to configure, while IPsec is deeply integrated into many network appliances; the right choice depends on compatibility, policy and operational needs.
A strong OpenVPN professional should also understand Linux, routing, firewalls, DNS, PKI and cloud networking. Experience with identity providers, monitoring and endpoint configuration helps turn a tunnel into a manageable access service.
The scope matters more than a fixed experience threshold. OpenVPN specialists handling several sites, certificate authorities, high availability or complex firewall policies should be able to demonstrate comparable designs and explain their security decisions.
Yes, OpenVPN configuration, testing and documentation can usually be handled remotely through controlled administrative access. On-site collaboration may still be useful when office firewalls, physical network equipment or industrial systems are involved.
Define who needs access, which systems must be reachable, how networks are connected and which authentication sources are available. For OpenVPN, current network diagrams, firewall details and compliance requirements allow a specialist to produce a safer design without guesswork.
A good OpenVPN implementation has documented routes, restricted permissions, protected keys, certificate revocation and tested recovery procedures. Ask the professional to explain logging, client onboarding, access removal and what happens when a certificate or server is compromised.
Typical OpenVPN deliverables include an architecture diagram, server and client configuration, certificate and key-management procedure, firewall rules, test results and operational documentation. A handover should also cover updates, monitoring, backup and incident response.
The average hourly rate of freelancers in Germany who have used OpenVPN in their recent projects is 107 €, which corresponds to a daily rate of about 859 € based on an 8-hour working day.
