Summary
As an experienced freelance Business Analyst, Requirements Engineer and (Proxy) Product Owner, I specialize in bridging the gap between business requirements and technical solutions. With my experience in agile (SAFe, Scrum, Kanban) and classic (waterfall) project management methods, I provide support from requirements gathering, (E2E) process and system design through implementation, integration and testing to rollout and launch. I am available to Incident and Problem Management for questions and hands-on troubleshooting.
My core competencies are in requirements engineering, process modelling (BPMN, EPK, UML) and interface design, and I have a proven track record in system integration, collaboration with various stakeholders and quality assurance. I ensure smooth project execution by coordinating and coaching cross-functional teams.
Functionally and methodologically, I can contribute knowledge in software industrialisation of ALM processes, data quality metrics and operations research. My technical background includes architecture design, pro-code development (J(2)EE/Java, RDBMS/SQL, Swagger/REST), but also low-code development at beginner level.
Complex integrations (SAP, MS Dynamics, Adyen), scalable architectures and process optimization complete my profile.
