Questions
Before we start
A quick overview of engagement, documentation and project support.
How does an engagement start?
With a short call or written brief. We capture the goal, current state, stakeholders, constraints and expected outcome, then define the work package.
Can you join only for the analysis phase?
Yes. I can prepare requirements, models, API contracts and acceptance criteria for your team without bundling development.
Do you work with private projects and NDAs?
Yes. Public cases omit confidential details, while working materials are handled within the agreed protected environment.
Can you support implementation after the specification?
Yes. I support engineers, clarify scenarios, assess changes and participate in acceptance so the documentation stays aligned with the product.
Which formats do you deliver?
Markdown, Confluence, BPMN, UML, Mermaid, OpenAPI, tables and data diagrams, selected to fit the team's workflow.
