About Me
Hello!
I'm a dedicated and adaptable tech professional with a strong background in automation testing, software development, and project management. My journey into technology started with a deep curiosity about how computers operate, and this passion has only grown over time.
After gaining valuable experience in data analysis at Korn Ferry and coordinating software projects at ZF Group, I now specialize in QA automation and SW development for Siemens Simatic IPC devices at Siemens Advanta Czech Republic.
Currently, I'm shifting my focus towards cybersecurity, actively pursuing a CompTIA Security+ certification, and enhancing my skills in Go. My goal is to transition into cybersecurity roles where I can leverage my experience in automation and scripting to protect and secure systems.
I recently completed the Google Cyber Security Certificate and am expanding my knowledge in network security, incident response, and Linux administration. I’m passionate about staying ahead in the rapidly evolving field of cybersecurity and aim to contribute to innovative security solutions.
Outside of work, I enjoy diving into new technologies, refining my skills, and exploring cybersecurity challenges. I also have a passion for tinkering with computers and playing Dungeons & Dragons.
Thank you for visiting my portfolio. Please explore my projects, and don't hesitate to reach out if you'd like to connect!
