SUMMARY

I have been passionate about technology since I was a child. That's why I chose to study Electrical and Electronics Engineering at Bahçeşehir University. After my graduation, I had several trainings and job experiences. Besides those, I have always been learning about and experiencing new technologies and systems. I love solving problems that I encounter while trying new subjects. I am also blogging on my website in my free time to share my knowledge with everyone.

With 7 years of experience, I am working as a Microsoft Systems Administrator at TAV Technologies right now. We provide in-house software product development, contractor for complex ICT projects, and IT operations management & consultancy for airports.
