About
Senior Mobile & Backend Engineer with 14+ years of experience delivering production-grade mobile applications and cloud-backed systems using C#, .NET, and Azure. Deep expertise in cross-platform development with Xamarin and .NET MAUI, including leading multiple Xamarin → .NET MAUI migrations and modernizing large, long-lived enterprise codebases. Alongside mobile engineering, I design and build secure, scalable REST APIs and backend services hosted on Azure App Services and Azure Functions, with strong focus on performance, observability, and reliability using Application Insights and Azure Monitor. Experienced in delivering end-to-end systems — from API design and identity integration (Azure AD / Azure AD B2C) to CI/CD pipelines (Azure DevOps, App Center), release stability, and production optimization. I work across mobile and backend layers to ensure systems evolve cleanly, remain maintainable, and scale reliably over time.
