Behind the code,
curiosity.

I am Kaan, also known as devilyxrd. As a Full-Stack Software Developer, I take end-to-end responsibility across web, mobile and backend development, from the first analysis of an idea to deployment.

01 — My approach

I think about an idea’s interface, the system behind it and how it will work in the real world together.

02 — Story

I see web, mobile and service development as different parts of the same product. When building an interface, I consider the data model; when building a backend, the user journey; and when preparing a release, the operational needs.

At Unitic, I work on enterprise web applications, management panels, CMS platforms and mobile products. I have contributed to development, integration and delivery on projects including YEE CMS, NoktaTR and the Turkish Art Platform, and I am actively involved in OYS & TYS, Motice and Mentorual.

At BilgeAdam Teknoloji, I developed full-stack web projects with C# and ASP.NET MVC. At IOTROCOP Technology, alongside web, mobile and IoT work, I individually designed and implemented a Raspberry Pi 4 advertising display for cafés and markets, manageable through a phone application, and a building-washing drone using ROS, Jetson Nano and fiber infrastructure, including their complete technical infrastructure.

As a freelancer, I developed e-commerce and congress websites, as well as corporate websites for companies and agencies, individually handling analysis, design, software and technical infrastructure from start to finish. My Raspberry Pi real-time vehicle tracking and navigation system is another project I developed entirely myself. My other work includes Devilyxrd Blockchain System, GAIA / AgroBlock and the Kadir Yücebaş clinic system, bringing together different software and device layers.
