EliasFrehner
Originating as a skilled mechanic, I demonstrated leadership in development and engineering projects involving multiple teams. Currently, I’m channeling my passion for coding and cyber security into a transition towards Software Engineering. I established a strong foundation through the Swiss military’s intensive 40-week cyber program, covering diverse areas such as assembly-based reverse engineering, pentesting, and coding. Beyond work, I am dedicated to continuous skill expansion. I’m presently engaged in contributing to multiple FOSS projects and mastering x86 reverse engineering. Alongside my practical experience, I am pursuing a Bachelor of Science in Computer Science to strengthen my academic background.
