About Me

Software Development Engineer in Test

I'm a software engineer who specializes in building the systems that ensure software quality. With over a decade of experience, I've evolved from traditional QA into a hybrid role that combines development expertise with quality engineering.

My work focuses on creating robust test automation frameworks, developing internal tooling, and architecting systems that make testing efficient and maintainable. I believe that quality is not a phase but an integral part of the development process.

Currently, I'm particularly interested in AI-assisted development. I actively use tools like Claude Code and explore how LLMs can enhance software engineering workflows. My personal project, ARPGCS, is a ~80,000 LOC AI-assisted full-stack application.

Beyond testing, I'm a capable full-stack developer. I work with Spring Boot and Vue.js, follow hexagonal architecture and DDD principles, and care deeply about clean code and sustainable software design. I'm currently pursuing a B.Sc. in Computer Science at FernUniversität Hagen alongside my professional work.

What I Bring to the Table

  • Framework Architecture: Designing and building test automation frameworks that scale and remain maintainable
  • Development Skills: Writing production-quality code in Java, TypeScript, and Python
  • Leadership: Experience leading test teams and communicating with stakeholders at all levels
  • AI Integration: Practical experience with AI-assisted development and LLM tooling
