What I'm looking for

I’m looking for a senior .NET role where I can own REST APIs and microservices, build strong Angular experiences, and work with cloud and CI/CD practices that value clean architecture, performance, and pragmatic delivery.

I’m a Senior .NET / C# full-stack developer with 12+ years of experience designing, building, and maintaining enterprise-grade web applications and RESTful APIs across multiple industries. I thrive on delivering clean, scalable systems end-to-end—from API design and data access to front-end experience.

In my recent role, I designed and maintained client-facing applications using .NET (from .NET 4.6.2 through .NET 10), ASP.NET Core, EF Core, and Dapper. I also built event-driven microservices integrated with RabbitMQ, improving decoupling and scalability across concurrent projects.

I bring strong full-stack delivery skills: Angular (9/13/21), AngularJS, TypeScript, RxJS, and component-based architectures with reactive state management. I’ve complemented .NET back ends with Node.js / Express.js services and worked on migrations—like moving a legacy PHP application to .NET 6 with Blazor Server to reduce technical debt and improve performance.

I’m also comfortable partnering with modern cloud and DevOps practices. I’ve deployed solutions on Google Cloud Platform (GCP), implemented CI/CD pipelines with Azure DevOps, and used tools like Docker, GitHub Actions, SwaggerUI, and Postman to keep quality high throughout delivery.
