About

I’m a .NET Developer with 8+ years of experience, looking for .NET Developer or Backend Programmer roles. I build web applications, RESTful APIs and backend services using C#, .NET Core, ASP.NET MVC and Entity Framework Core, with front-end work in Angular. My experience also includes MySQL and PostgreSQL (including a database migration), Git/GitHub, Docker, CI/CD and unit testing. I enjoy turning business requirements into reliable, maintainable software and supporting it through to production.
