Over more than 20 years in software quality assurance, I have tested complex web, mobile, and desktop applications across public transport, healthcare technology, financial services, SaaS, and e-commerce.
My work combines structured manual testing, exploratory testing, test planning, API testing, and end-to-end automation. I focus not only on whether software meets its technical requirements, but also on whether it supports a clear, reliable, and intuitive user journey.
The following projects represent selected highlights from my QA career.
SaaS, e-commerce, public transport, and test automation
For Yatta Solutions, I have contributed to the quality assurance of Yatta Checkout, a configurable platform supporting checkout, customer-account, payment, licensing, and subscription workflows.
One significant implementation is the checkout used by the NVV Mobil application. As lead tester for the introduction of the Deutschlandticket within NVV Mobil, I was responsible for testing a nationally significant ticketing product built on the Yatta Checkout platform.
The project combined reusable platform functionality with transport-specific requirements, including passenger onboarding, payment processing, ticket management, pricing, and complex validity rules.
Led testing activities for the Deutschlandticket launch within NVV Mobil
Tested customer-facing checkout, account, authentication, payment, and licensing workflows
Planned and executed functional, integration, regression, and exploratory testing
Verified transport-specific fare and ticket-validity rules
Tested interactions between mobile applications, web interfaces, APIs, and administrative systems
Designed and implemented end-to-end tests using Playwright and TypeScript
Integrated automated tests with GitHub and CI/CD workflows
Created reusable test structures, fixtures, and helper functions
Investigated failures across application, network, and deployment layers
Worked closely with developers, product owners, and other project stakeholders
My work supported the successful introduction of the Deutschlandticket within NVV Mobil while also strengthening the quality and automated regression coverage of the underlying Yatta Checkout platform.
Regulated dental CAD software
From 2016 to 2024, I worked on the quality assurance of sophisticated dental CAD applications at exocad and, following its acquisition, Align Technology.
The software supported complex professional workflows and operated within a regulated environment. Testing therefore required a particularly systematic approach, strong attention to detail, and clear, traceable documentation.
Tested complex desktop software used by dental laboratories and clinical professionals
Designed and executed functional, regression, integration, and exploratory tests
Verified intricate workflows involving 3D dental design and manufacturing processes
Worked within established quality-management and regulated-development processes
Documented defects clearly and reproducibly for international development teams
Collaborated with developers, product specialists, technical writers, and other QA engineers
Assessed both technical correctness and the usability of specialist workflows
Contributed to release testing across multiple product versions
My work helped maintain the reliability and usability of specialist software on which dental professionals depend for complex, accuracy-critical workflows.
QA management and team leadership
For two years, I served as QA Manager at NetDev in Brighton, combining hands-on testing with responsibility for coordinating quality assurance activities across software projects.
The role broadened my experience beyond test execution to include QA planning, prioritization, team coordination, and communication between technical and business stakeholders.
Managed and coordinated day-to-day QA activities
Planned testing across concurrent development projects
Assigned priorities and balanced testing effort against release requirements
Supported and guided members of the QA team
Established consistent approaches to test planning, execution, and defect reporting
Worked closely with developers, project managers, and business stakeholders
Assessed release readiness and communicated quality risks
Remained actively involved in hands-on functional and exploratory testing
The role strengthened quality ownership across the development process and gave project stakeholders clearer visibility of testing progress, release risks, and overall product readiness.
My wider project experience includes web, mobile, desktop, and SaaS applications in financial services, enterprise software, public transport, and other business-critical environments.
Depending on the project, my responsibilities have included:
QA strategy and test planning
Manual functional and regression testing
Exploratory and risk-based testing
Mobile and cross-browser testing
REST API testing
End-to-end test automation
CI/CD integration
Defect analysis and reporting
Requirements and acceptance-criteria reviews
Release-readiness assessment
Usability and user-journey evaluation
Collaboration with distributed and international teams
Effective QA is not simply a matter of checking whether requirements have been implemented. It means understanding the product, anticipating how people will actually use it, and identifying the situations in which technology may fail them.
I bring together extensive hands-on testing experience, technical understanding, and a strong focus on usability. Whether I am joining an established QA team, leading testing for a release, or introducing practical automation, my objective remains the same: to help deliver software that users can trust.
I am available for freelance QA engineering, test automation, release testing, and short-term project support. If you need an experienced tester who can quickly understand a complex product and contribute with minimal onboarding, please get in touch.
