What I'm looking for

Senior Backend / Fullstack .NET Developer. Looking for full-time, remote (worldwide) roles; open to relocation to Europe.

At verasaha.com, I’m building a multi-tenant SaaS architecture from scratch, including its backend, technical infrastructure, and domain-based business rules. I’ve configured its production environment with Docker and Nginx and designed scalable RESTful APIs.

Across my work at İmpark Eğitim Bilişim, Teknobay Bilişim, and other organizations, I developed integrations, APIs, and reporting infrastructure for business systems. I’ve also worked on enterprise software and long-term system sustainability in public sector projects.
