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.

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.

About the technology
Secure network access
OpenVPN is an open-source virtual private network technology for encrypted connections over untrusted networks. It uses TLS for authentication and can connect remote users, offices, cloud environments and private services. Companies use it to protect traffic without exposing internal systems directly to the public internet.
Core deployments
OpenVPN supports several network patterns and access needs:
- Remote access for employees, contractors and support teams
- Site-to-site links between offices, data centers and cloud networks
- Controlled access to internal applications and administration interfaces
- Encrypted connections for distributed infrastructure and field operations
The right design depends on identity management, routing, device ownership and the sensitivity of the systems behind the connection.
Ecosystem and tooling
Professionals work with OpenVPN Access Server, community OpenVPN, OpenVPN Connect clients and common Linux, Windows, macOS, Android and iOS environments. They also handle certificate authorities, public key infrastructure, firewall rules, DNS, routing tables and network address translation. Integration with directory services, multi-factor authentication and logging improves control and traceability.
When companies need specialists
Freelance expertise is useful during a new VPN rollout, a migration from legacy remote access or a redesign of fragmented office connections. It is also valuable when access is slow, routes are unreliable, certificates are difficult to manage or security reviews expose gaps.
- Review an existing OpenVPN topology and configuration
- Create profiles and policies for different user groups
- Connect offices, cloud networks and private services
- Diagnose routing, firewall and authentication problems
In Germany, specialists may support teams remotely while coordinating on-site work for network changes or regulated environments.
Delivery and maintenance
A strong professional documents the network design, trust model, configuration choices and recovery process. They automate repeatable setup where appropriate, separate user and service access, rotate certificates safely and establish useful monitoring. Clear handover materials help internal teams operate the environment after the engagement ends.
What strong experts bring
Look for practical experience with encrypted tunnels, routing and access control rather than certificate configuration alone. Strong specialists can explain why OpenVPN is suitable compared with WireGuard, IPsec or a managed zero-trust service, and when another option is better. They test failure scenarios, limit privileges and communicate clearly with security, infrastructure and application teams.
Frequently asked questions
Curious about OpenVPN? Here are the answers that come up again and again.
OpenVPN is used to create encrypted remote-access and site-to-site connections. Companies use it to connect users, offices, cloud networks and private applications across the public internet while controlling authentication and routing.
OpenVPN offers broad client support, mature access controls and extensive configuration options. WireGuard is often simpler and lightweight, while IPsec integrates closely with many network appliances; the right choice depends on compatibility, identity management, performance and operational requirements.
A capable OpenVPN specialist should understand Linux networking, firewalls, DNS, routing, certificates and public key infrastructure. Experience with directory services, multi-factor authentication, cloud networking and security monitoring is also valuable.
A small remote-access setup may suit a specialist familiar with OpenVPN configuration and certificate management. Larger or business-critical environments require someone who has designed resilient routing, handled identity integration, documented controls and diagnosed failures across networks.
Yes, many OpenVPN engagements can be completed remotely through secure access, configuration reviews and documented change processes. On-site work can still be useful for physical network changes, isolated systems or teams that need local coordination in Germany.
OpenVPN Access Server provides a managed interface for user administration, connection profiles and access policies. It can suit teams that want simpler operations than maintaining a community deployment, while larger environments may still need custom integration and infrastructure expertise.
A good OpenVPN implementation uses strong authentication, limited network reachability, protected keys and clear certificate lifecycle processes. Ask for topology documentation, logging guidance, recovery procedures and evidence that routing, revocation and failure scenarios were tested.
An OpenVPN professional may deliver a network design, server and client configuration, user profiles, certificate setup, firewall rules and identity integration. The engagement should also include testing, operational documentation and a clear handover for internal teams.
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.
