What I'm looking for

I’m looking to build scalable .NET services and APIs with DDD/CQRS, collaborate in global teams, and ship reliable, well-tested systems—where performance, maintainability, and clean architecture are non-negotiable.

I’m a Senior .NET developer with 19+ years building scalable backend services and modern web UIs. I specialize in .NET Core/.NET 8, C#, Entity Framework, and RESTful API development, bringing DDD, Clean Architecture, microservices, and TDD to every project. I’m also hands-on with Angular and TypeScript to deliver dynamic user experiences.

In recent roles, I design event-driven integrations using Google Pub/Sub and Azure Service Bus, optimize performance with Redis caching, and improve reliability through idempotency in critical workflows. I build unit-tested, maintainable codebases and develop reusable internal components (like a CQRS mediator with FluentValidation), using tools such as GitHub Copilot and Claude Code to accelerate delivery.
