Description

Software Engineer with over 15 years of experience in test automation, software development, and quality assurance.

My focus is on developing scalable test automation frameworks (E2E, UI, API) – at the same time, I have also been working as a full-stack developer in the Java and .NET environment for many years.

I design, develop, and maintain automated tests based on Java, C#, Selenium, Playwright, Cucumber/BDD, JUnit, NUnit, MSTest, and integrate them seamlessly into modern CI/CD pipelines (GitLab CI, Jenkins, Azure DevOps).

As a full-stack developer, I am experienced in both backend (Java Spring, .NET / C#, REST APIs, Microservices) and frontend (Angular) and can closely integrate test automation with application development.

Industry Focus: Industry, Manufacturing, Solar/Energy Technology, Signaling Technology & Embedded-related Systems. This gives me a deep understanding of complex, distributed, and safety-critical systems.

My Focus Areas:

• Development and expansion of test automation frameworks (Java / C#)

• E2E, UI, and API test automation

• Full-Stack Development (Backend + Frontend)

• CI/CD Integration (Docker, Kubernetes, Azure)

• Architecture, Code Reviews, and Quality Concepts

• Support for Agile Teams (Scrum, Kanban, SAFe)

Availability:

• Remote (fully)

• On-site at the client's location in the DACH region upon agreement

• Flexible engagement models (part-time/full-time in projects, sprint-based, project packages)

I reliably support companies in the DACH region with all matters related to test automation, quality assurance, and full-stack software development – from framework design to production-ready implementation.
