About Me

Engineer, educator, and builder.

I'm a software engineer and product-focused developer with experience building modern web applications, AI-powered systems and educational technology products. My background combines engineering, entrepreneurship and teaching. Alongside professional software development experience, I've founded educational initiatives that introduced coding and robotics to over 5,000 students.

I hold an MSc in Systems & Control Engineering from Boğaziçi University. Today, I focus on building scalable frontend and full-stack systems, integrating AI workflows into products and helping ideas move from concept to production. I enjoy bridging the gap between complex technology and real people by designing clear, human-centred tools.
