• Strong expertise in ASP.NET Core, Web API, and middleware.
• Solid experience with Relational Databases (MS SQL / PostgreSQL) and ORM frameworks (Entity Framework Core).
• Understanding of microservices architecture and distributed systems.
• Experience with Docker (Kubernetes experience is a plus).
• Familiarity with CI/CD pipelines (GitHub Actions, Azure DevOps, GitLab CI, etc.).
• Proficiency in writing unit and integration tests.
• Good understanding of design patterns, SOLID principles, and clean architecture.
• Upper-intermediate or higher level of English (written and spoken).

Nice to Have

• Frontend exposure (React, Angular, or Blazor).
• Previous experience in team leadership or technical mentorship.

We Offer

• Competitive compensation (based on experience and skill level).
• Flexible working hours and remote-friendly culture.
• Professional growth opportunities and support for certifications.

• Modern tech stack, open-minded team, and challenging projects.
