I am a Full Stack .NET Core Developer with 5+ years of experience building scalable web, desktop, mobile, cloud, and device-integrated software.

I enjoy solving real-world business problems with clean architecture, performance-focused engineering, and practical product thinking. My work spans ASP.NET Core, microservices, WPF, WinForms, React, MERN, cloud infrastructure, DevOps, payment integrations, CRM/ERP systems, and hardware-based applications.

I have always been deeply curious about computers and technology. A lot of my learning came from exploring devices, operating systems, software ideas, and real projects. That curiosity is still the reason I love building innovative things and putting my full effort into every system I create.
