What I'm looking for

I seek a role where I can modernize and scale systems using .NET and cloud technologies, lead technical decisions, mentor engineers, and work in a collaborative Agile team focused on quality and observability.

I am a Senior Software Engineer specialized in the .NET ecosystem (C#, .NET, Blazor) with experience across banking, education, and connectivity. I focus on Clean Architecture, DDD, CQRS and modern tooling to deliver scalable full-stack and cloud solutions on AWS and Azure while improving performance and maintainability.

I have led platform modernizations, migrated legacy systems to .NET 9 and Blazor WebAssembly, replaced heavy stored procedures with Entity Framework, and introduced automated testing and observability. I collaborate closely with product and business teams in Agile environments and drive engineering best practices through code reviews and technical leadership.
