Get to know
I have been working on software for over 10 years and still improving myself in this field. After taking 2 years of software course, I have written expert reports, actuary calculations, file tracking software, and auto control systems for insurance companies and law firms for 8 years — and I still have an active role.
For the last 6 years, I have been a security company manager in Gayrettepe Metro, the biggest metro project in Istanbul. I also took on a dual role when the IT department staff left; the programs I wrote are still in active use in Halkalı Metro, the second biggest metro project in Istanbul.
Alongside desktop and web, I also build Android applications using Java and Kotlin — from native UIs with Jetpack to REST API integrations and Firebase-backed backends.
As a Security Chief with 6+ years on major metro projects, I design and operate end-to-end CCTV camera systems, access control, security automation and IT infrastructure solutions — from network planning to NVR/DVR setup, integration with face-recognition and automated reporting. I'm still actively delivering these services today.
