Description

You need specifications that work — not requirements documents that fall apart in the first review. That's exactly where I come in.

As a Senior Business Analyst with 42 years of project experience and a degree in mathematics, I support teams in cleanly eliciting, structuring, and transforming complex requirements into testable specifications. Since 2024, I have been systematically integrating AI models (Claude, ChatGPT) into this process — not as a gimmick, but as a tool that finds gaps, uncovers contradictions, and accelerates documentation.

What sets me apart: I have developed my own approach to how AI concretely functions in Business Analysis — from CLAUDE.md as a control file to reusable skills for requirements elicitation, acceptance criteria, and quality gates.

My focus areas:

AI-assisted requirements elicitation and specification
User stories, acceptance criteria (Given/When/Then), functional specification
Confluence-based documentation structures
Business analysis in agile teams (Scrum, JIRA, Confluence)
Impact analysis and requirements traceability
Stakeholder management and workshop moderation

I have also developed a series of these on LinkedIn:

Industries: Banks, Telecommunications, Public Sector, Finance, Insurance

Typical projects: Greenfield specifications, requirements consolidation from workshop output, review of existing documentation, introduction of AI-supported BA processes in the team

International project experience in Europe, Asia, Middle East, and USA.
