Summary
Business Analyst and Requirements Engineer with over 5 years of experience at the interface of business and IT. My focus is on digital platforms, e-commerce, B2B portals, LMS systems, and cross-system IT solutions.
I support companies in structured requirements gathering, business analysis, process definition, user story creation, backlog prioritization, UAT planning, and go-live support. In doing so, I combine business understanding with technical depth and work confidently with business units, IT teams, external service providers, and international stakeholders.
I'm particularly strong in projects where unclear requirements need to be turned into implementable specifications, clear acceptance criteria, testable solutions, and stable releases. I have experience with AEM, SAP Commerce Cloud / Hybris, SAP S/4HANA, Jira, Confluence, ServiceNow, SQL, BPMN 2.0, Scrum, Kanban, and UAT.
Additionally, through my training and practical work in web security / bug bounty, I bring a strong sense of quality and security to digital projects.
