Hi, I'm Bahadir Buyuktopac
Based in Uzunköprü. I build web applications, develop mobile apps, and design custom IoT hardware. I simplify complex technology into clean, fast, and working solutions.
About Me
I live and work in Uzunköprü, Turkey. I focus on software development, web design, and hardware engineering. From brainstorming to coding, and PCB layout to physical assembly, I handle the entire product cycle.
I value readable code, honest communication, and solid architecture. No corporate fluff or over-engineered solutions—just software that gets the job done.
