About

🚀 I'm not just someone who builds products—I live with them. I'm not just a user of knowledge—I transform it. I'm an engineer, a leader, and a strategist driven by impact and innovation. For over 25 years, I have contributed to Turkey’s evolving tech landscape by building projects from the ground up, leading security architectures, delivering innovative products, and empowering the teams that shape the future. From cybersecurity and software development to API integrations, R&D management, and product lifecycle leadership—I’ve partnered with hundreds of institutions on their digital transformation journeys. 🧠 My academic curiosity led me to earn 2 associate degrees, 4 bachelor's, and a master's degree. I firmly believe in lifelong learning—and sharing that learning. 👥 I am a leader who values team spirit, nurtures young talent, mentors with purpose, and sees the human at the heart of every product. 🌍 Today, I’m ready to join forward-thinking organizations that view cybersecurity not just as a product, but as a culture—rooted in sustainability, ethics, and innovation. 📌 I’m open to senior roles such as CTO, R&D Manager, or Tech Leader—at organizations that aim to build a better, safer, and smarter future.
