How I Can Help
I am a systems engineer and requirements manager with about 13 years of experience in safety-related systems: railway signalling (ERTMS/ETCS, CENELEC EN 50126/50128/50129) and automotive (Automotive SPICE at system level, ISO 26262).
I work full-time as a Senior Business Analyst at GlobalLogic, so this is not a consulting offer. It is an overview of the areas I know well and the ways I am happy to share that knowledge: conversations with engineering teams, feedback on requirements and architecture, and the tools I build.
Areas of Expertise
Requirements engineering and management
Clear, verifiable and traceable requirements, from stakeholder needs down to system and software level.
- Requirements elicitation and analysis
- Writing verifiable system requirements
- Traceability between requirements, design and tests
- Requirements management in IBM DOORS and IBM Jazz
- Change and baseline management
Railway signalling (ERTMS/ETCS)
From 2013 to 2026 I worked at Bombardier Transportation (ZWUS) and Alstom as a software engineer, product owner, system engineer, requirements manager, team leader and system engineering consultant.
- ERTMS/ETCS system and software development
- RAMS lifecycle according to EN 50126
- Safety-related software according to EN 50128
- Safety Case and safety-related electronic systems according to EN 50129
Automotive: ASPICE and ISO 26262
Since 2022 at GlobalLogic: system-level requirements for automotive projects following Automotive SPICE.
- System requirements analysis at ASPICE SYS level
- Functional safety according to ISO 26262
- Traceability and consistency between requirement levels
- Working with stakeholders to clarify requirements
System architecture
Breaking a system down into components and interfaces, with safety requirements in mind from the start.
- System decomposition and interface definition
- UML modelling
- Redundant architectures such as 2oo2 and 2oo3
- Allocation of requirements to system elements
Safety and reliability analysis
Analyses that show how a system can fail and whether the remaining risk is acceptable.
- Failure mode and effects analysis (FMEA)
- Fault tree analysis (FTA)
- Hazard analysis and safety requirements
- SIL, THR and reliability metrics (MTTF, MTBF)
Engineering tools and automation
A software background that helps me connect requirements with implementation.
- C and C++
- Python, TCL/Expect and Bash for test and process automation
- Git and code review in Gerrit
- My own tools for log analysis and engineering work
Team leadership and product ownership
Experience as a team leader and product owner in a safety-related railway environment.
- Agile/Scrum in safety-related projects
- Backlog and priority management
- Supporting engineers in working with requirements and standards
Ways to Collaborate
Technical conversations
Exchanging experience with engineers and teams on requirements engineering, ERTMS/ETCS, CENELEC standards or ASPICE.
A second opinion
Informal feedback on a set of requirements, traceability or an architecture idea, based on my own experience.
Knowledge sharing
I am open to giving a talk or leading a discussion for a team or community on requirements and functional safety.
My tools
Feedback, bug reports and contributions to my tools for requirements management and log analysis are welcome.
Standards, Tools and Languages
Standards and process models
Tools
Programming languages
Tools I Build
These tools grew out of everyday work with requirements and test logs.
ReqManTool
A local-first requirements management tool inspired by DOORS: hierarchical requirements, traceability links and ReqIF/CSV export, stored as plain JSON files in git.
View on GitHubLogViewer
A cross-platform log viewer (Qt 6, C++20) for XML, CSV, Vector CAN/ASC, AUTOSAR DLT and other formats, designed for very large logs.
View on GitHubCAN Pro-Decoder
A CAN log analyser for Windows: decodes Vector ASC logs with DBC files and plots signals on a shared timeline.
