I have been passionate about technology since childhood, which led me to study Electrical and Electronics Engineering at Bahçeşehir University. After graduating, I attended several trainings and gained valuable professional experience. I have always been eager to learn and explore new technologies and systems, and I enjoy solving the challenges I encounter while experimenting with them. In my free time, I share my knowledge by blogging on my personal website. With 8 years of experience, I am currently working as a System Specialist at Anadolu Sigorta.
