What I'm looking for

I’m looking for a team where I can lead scalable .NET backend and REST API work on Azure—shipping secure, observable systems with clean architecture, CI/CD automation, and real performance tuning.

I’m a Senior .NET Developer with over 5 years of hands-on experience building scalable, cloud-ready applications using C#, ASP.NET Core (.NET 8/9), EF Core, Dapper, and ADO.NET across SQL Server and MySQL. I design REST APIs using Clean Architecture, CQRS, MediatR, and SOLID principles, with a strong focus on performance optimization and reliable integrations.

In recent roles, I lead backend development for a government-level emergency and disaster management system, implementing Azure AD-based authentication/SSO, Azure DevOps CI/CD, and observability with Application Insights and Azure Monitor. I also develop large-scale administrative platforms with optimized REST APIs, JWT authentication, complex multi-step workflows, and Razor Pages dashboards—using Docker, Kubernetes (AKS), and tools like Cursor and GitHub Copilot to keep delivery efficient and code quality high.
