A little about me

Kamil Şen

I’m a backend-focused Full Stack Developer. I build backend systems with .NET and Node.js, and user interfaces with React, Next.js and Vue. I work on SaaS platforms, microservice architectures, real-time applications and AI integrations.

For me, the most important part of the job is turning a complex problem into a clear solution and building a system that can be maintained for years.

  • REST APIs and microservices
  • Third-party integrations
