About me

Senior ALM Specialist bridging Engineering & IT. I combine 25+ years in Requirements Management with hands-on IT Operations (Hosting/VMware). As a ReqIF expert (REQTEAM co-founder), I specialize in complex data exchange & migration. I ensure your tools are not just defined, but operational.

With over 25 years of experience in Requirements Management and Engineering IT, I offer a rare combination of deep methodological expertise and hands-on IT operations skills. I don’t just consult on processes; I build, host, and maintain the infrastructure that makes them run.

Unlike many consultants who only know the "user side" of tools, I bring over 10 years of hard IT infrastructure experience (VMware/Proxmox). I speak the language of your IT department and translate it for your engineering teams to ensure compatibility, performance, and compliance.

My Core Value Proposition:

Technical Depth: I operate my own server racks and host mission-critical environments. I know what happens "under the hood" of your ALM tools.

ReqIF Authority: As co-founder of REQTEAM GmbH, I possess code-level understanding of the ReqIF standard. I solve complex data exchange challenges where standard tools fail.

Migration Expertise: I specialize in moving data safely from legacy systems (like IBM DOORS) to modern platforms, ensuring data integrity and traceability.Detailed Service Portfolio:

1. ALM Strategy & Tool Architecture
Selection and evaluation of ALM tools (IBM ELM, PTC Codebeamer, Polarion, Jama, etc.).
Design of toolchains that support Agile (SAFe, Scrum) and V-Model methodologies.
Development of migration strategies for legacy decommissioning.

2. IT Operations & Hosting (Managed Services)
Technical hosting and administration of ALM environments.
Infrastructure management based on VMware and Proxmox.
Performance tuning, upgrades, and patch management for engineering applications.
Ensuring high availability for mission-critical development environments.

3. Data Migration & Interoperability (The "Hard" Stuff)
ReqIF Specialist: Creating custom exchange configurations and fixing broken XML data structures.
Data Migration: executing complex migrations (e.g., DOORS to Codebeamer/Polarion) with a focus on preserving history and links.
Integration: Connecting siloed tools via OSLC and custom interfaces.

4. Requirements Engineering & Consulting
Certified Scrum Product Owner: Bridging the gap between agile teams and formal requirements.
Requirements Management according to standards (Automotive SPICE, ISO 26262, EN 50128).
Training and coaching for tool usage and methodology.
Technical Skills & Tools:

ALM Platforms: IBM Engineering Lifecycle Management (DOORS Classic, DOORS Next,ELM) PTC Codebeamer, Siemens Polarion, Jama Connect, Jira.
Standards & Formats: OMG® ReqIF, OSLC, XML.
Infrastructure: VMware ESXi, Proxmox VE, Linux, Windows Server, Docker.
Scripting: DXL (DOORS Extension Language), Scripting for data manipulation.

Industry Focus: My experience is rooted in safety-critical and regulated industries:

  2. Aerospace & Defense
  3. Rail / Rolling Stock
  4. Medical Technology
