About Me

Hello!

I'm a practical and adaptable tech professional with a background in QA automation, software development, and project coordination. I currently work at Siemens Foundational Technologies, where I focus on Python-based test automation and software development for Simatic IPC devices.

To support hardware-related needs, I’ve been expanding into C++ development—working on tasks like reading CPU sensors—and deepening my knowledge of tools like gRPC to improve system integration and communication.

Earlier in my career, I gained valuable experience in data analysis at Korn Ferry and in project coordination at ZF Group, which gave me a broad perspective across tech disciplines.

While my primary focus is development and automation, I maintain a strong interest in cybersecurity. I’ve completed the Google Cybersecurity Certificate, continue learning about Linux administration, and occasionally tackle security-focused challenges to sharpen my skills.

Outside of work, I enjoy learning new technologies, tinkering with hardware and code, and running gritty, low-fantasy tabletop RPG campaigns.

Thanks for visiting. Feel free to browse my projects or get in touch if you're interested in collaboration or just talking tech.
