About Me
I have been actively working in the information technology sector since 2002. I began my career by receiving software education at a vocational high school and have held various technical and administrative positions since then. I played an active role in all stages of post-sales processes, from the installation of products to their commissioning and project planning. Additionally, I worked on the customer side, taking on effective roles in both administrative and technical processes such as the design, relocation, and restructuring of large-scale data centers. Throughout these processes, I provided technical support and contributed to the successful completion of projects.
In short, since I started in the industry at a time when specialization was not yet so sharply defined, I gained broad technical and comprehensive experience ranging from software, networking, and cybersecurity to infrastructure, project management, and customer relations.Having witnessed the transformation of technology firsthand, I can evaluate both the past and the present of the industry from a holistic perspective.
I am considering leveraging this experience I have gained across different disciplines to continue my career as a Cybersecurity Analyst.

Work Experience
Due to health issues experienced in 2023, I took a break from work and completed my treatment process that lasted about 1.5 years. After this period, I focused on personal development instead of job hunting.
During this time:
Worked on cryptology algorithms, acoustic steganography and AI-based security methods
Developed scenario-based applications by testing open source security tools in depth
Improved my proficiency in social media intelligence (SOCMINT) and visual data analysis
This period has been a process where I regained my health and developed my technical competence at an interdisciplinary level.
Therefore, I want to evaluate my experiences more as an analyst.
1. SDN Migration & Network Transformation
