Summary

Hands-on software tester and data analyst for measurement data and business processes, with a strong support mindset. Planning and carrying out manual functional tests, integration, system, and acceptance tests. Testing compatibility (API interfaces), usability, and transferability (migrations). Careful defect analysis and tool-based defect tracking. Building and maintaining automated tests with Robot Framework and Python. Regression tests for Continuous Integration / Deployment. Many years of experience working with developers, business teams, and users, remote/on-site. Industry experience in inventory management & logistics, e-commerce, commercial vehicles, healthcare (billing systems, measurement data pharma / regulated area), research, public sector, energy industry, insurance, real estate, and creative industries. The projects so far have required independent and careful onboarding into new topics as well as an analytical, structured approach so that even complex system relationships could be understood, tested, and explained. I have worked in teams of 3 to more than 30 people and on projects with several hundred project days. Projects that combine software testing, data analysis, and visualization are of special interest to me.
