About Me

I am a graduate of the Technical University of Cluj-Napoca, with a Bachelor’s degree in Telecommunications Systems and Technologies, and I am currently pursuing a Master’s degree in Cybersecurity at Transilvania University of Brașov. My academic background combines engineering fundamentals with a growing focus on secure and reliable software systems.

I am particularly interested in front-end and application development, where I enjoy transforming complex requirements into clean, structured, and user-friendly interfaces. Alongside UI development, I have a strong interest in cybersecurity topics such as ethical hacking, security testing, and understanding how vulnerabilities can emerge at both application and infrastructure levels.

Throughout my studies and personal projects, I have worked with multiple programming languages and technologies, ranging from low-level concepts to modern web and mobile frameworks. I value continuous learning, practical experimentation, and hands-on projects as the best way to strengthen my technical skills.

I am motivated, collaborative, and adaptable, with strong communication skills and a problem-solving mindset. I am eager to apply my knowledge in real-world environments, contribute to meaningful projects, and grow professionally while working alongside experienced engineers.
