What I'm looking for

I seek backend/cloud roles where I can design scalable architectures, mentor teams, use Azure services, and improve platform reliability.

I am a Senior .NET Backend Engineer focused on delivering high-quality features and driving architectural excellence across cloud-native platforms.

I build scalable, maintainable RESTful APIs with strong error handling and performance optimizations, and I have deep experience with C#, .NET Core, Entity Framework Core, PostgreSQL, SQL Server and MongoDB.

I leverage Azure services—Functions, Blob Storage, App Service, Service Bus and Azure SQL—to integrate platforms and improve scalability, while championing CI/CD with GitHub Actions, CircleCI and Azure DevOps.

I mentor junior engineers, contribute to architectural decisions, and collaborate with product and business teams to align technical solutions with business goals.
