Focus

Frontend systems, backend services, product quality, and AI-assisted user experiences.

Core Stack

React, Next.js, Blazor, Node.js, , TypeScript, C# .NET - Blazor / WPF and cloud-backed integrations (Azure / AWS).

about

Developer bridging design and engineering, with formal training in UI development and software engineering, a background in visual communication, and production experience spanning React, Next.js, Blazor, ASP.NET Core, serverless cloud, and AI integration.

I build high-quality, scalable applications across the stack, from responsive React, Next.js, and Blazor frontends to robust Node.js and ASP.NET Core backends.

My foundation combines front-end and API development studies at Medieinstitutet with advanced C# and .NET coursework at Malmo University.

Before moving into software development, I worked with visual communication, marketing, and intercultural collaboration, which still shapes how I approach product quality and UX.
