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
BOM fundamentals
A Bill of Materials, or BOM, is a structured list of every component, material, assembly and document needed to make or maintain a product. It defines quantities, part relationships, revisions and approved alternatives. A reliable BOM connects product design with purchasing, production, service and compliance.
Product structures
BOM specialists create structures suited to the product and the business process. They work with engineering BOMs, manufacturing BOMs, service BOMs and configurable product variants. Their deliverables can include part classifications, assembly relationships, revision rules, effectivity data and clear ownership for each record.
Systems and tooling
The work often crosses CAD, PLM, ERP and supply-chain systems. Experts map data between tools such as SAP, Teamcenter, Windchill, Autodesk and other product lifecycle environments. They also handle import templates, integration rules, change workflows, permissions and data validation so that one product structure remains consistent across departments.
When expertise matters
Companies bring in freelance BOM specialists when product data is incomplete, fragmented or difficult to release into production. Common needs include:
- Consolidating duplicate parts and inconsistent naming
- Migrating BOM data during a PLM or ERP rollout
- Establishing engineering-to-manufacturing handover rules
- Preparing structures for configurable products or service operations
Cologne collaboration
Manufacturers, industrial technology companies and product teams in Cologne may need focused support for a plant, rollout or product family. A freelancer can work remotely with local stakeholders or join on-site workshops when physical products, production processes or supplier data require direct review. German and English communication may both matter across engineering, purchasing and operations.
Quality signals
Strong professionals understand both data detail and production consequences. They ask how parts are released, who controls revisions, how alternatives are approved and which system is authoritative. Look for experience with traceable change management, clean master data, access controls, integration testing and documentation that users can apply without guesswork.
Frequently asked questions
Curious about Bill of Materials? Here are the answers that come up again and again.
A Bill of Materials defines the components, materials, assemblies and documents required to build, service or maintain a product. It helps teams align design, procurement, production, quality and after-sales work around a controlled product structure.
A BOM is more than a flat parts list because it can show hierarchical relationships, quantities, revisions, effectivity and approved alternatives. A product configuration adds rules for selecting valid variants, while a BOM records the structure needed for a specific product context.
A strong Bill of Materials specialist often understands PLM, ERP, CAD, master data management and engineering change control. Knowledge of manufacturing processes, procurement, service structures and integration testing is also valuable.
The right level depends on the scope, data quality and systems involved. A focused cleanup may need strong data and process skills, while an ERP or PLM transformation calls for experience with migration, governance, integrations and cross-functional releases.
Yes, much of the Bill of Materials work can be handled remotely through system access, workshops and documented reviews. On-site sessions in Cologne can still help when teams need to inspect production flows, physical assemblies or supplier processes.
Bring in a BOM freelancer when structures are inconsistent, releases are delayed, systems disagree or a migration is creating operational risk. External expertise is especially useful when internal teams need a neutral owner for rules, cleanup and validation.
Ask the specialist to explain revision control, part numbering, effectivity, alternatives and ownership in practical terms. Quality work produces traceable structures, validated interfaces, clear documentation and fewer discrepancies between design, purchasing and production.
A capable Bill of Materials freelancer should be comfortable with the systems used in the project, such as SAP, Teamcenter, Windchill or Autodesk environments. Tool knowledge matters, but the ability to map data, govern changes and preserve product meaning across systems matters just as much.
