Cross-brand design system
Focus: Analysis of the causes of recurring layout deviations in design system components. The cause was the integration of visual regression tests (BackstopJS) into the build and approval process: deviations were not blocked, and reference images were replaced without approval.

About the technology
What Blazor Does
Blazor is Microsoft's web UI framework for building interactive applications with .NET and C#. It lets teams share application logic between client and server while using Razor components to structure the interface. Depending on the project, code can run in the browser through WebAssembly or on the server through interactive rendering.
Core Building Blocks
Blazor applications are built from reusable Razor components with parameters, events, forms, validation, and data binding. Strong specialists work with ASP.NET Core, dependency injection, authentication, authorization, Entity Framework Core, and REST or gRPC services. They also understand routing, state management, rendering modes, and component lifecycle behavior.
Typical Applications
Blazor fits products that need rich interactions without adopting a separate JavaScript application stack.
- Internal business portals for operations, finance, and service teams
- Customer dashboards with forms, workflows, and live data
- Administration interfaces for enterprise systems
- Reporting tools with filters, charts, exports, and role-based access
- Line-of-business applications connected to Microsoft services
Ecosystem And Tooling
The framework sits within the .NET and ASP.NET Core ecosystem. Projects commonly use Visual Studio or Visual Studio Code, NuGet packages, Microsoft Identity, Azure services, SQL Server, and testing tools for component and end-to-end validation. Teams may also integrate JavaScript libraries through JavaScript interop when a browser capability or established UI package is not available in .NET.
When Expertise Matters
Companies often bring in freelance specialists when a .NET team needs frontend capability, an existing portal requires modernization, or a proof of concept must become a maintainable product. Relevant work includes choosing between Blazor Server and WebAssembly, improving load time, introducing reusable design systems, connecting APIs, and resolving rendering or state issues. Experience with accessibility, security, deployment, and observability matters in production systems.
Signs Of Strong Specialists
A capable Blazor professional asks how users, data, hosting, and authentication should work before selecting a rendering model. They separate reusable components from application-specific logic, keep state predictable, and test behavior rather than relying on visual checks alone. They can explain trade-offs against React or Angular, diagnose browser and server boundaries, and leave clear documentation for the team taking over the codebase.
Frequently asked questions
Curious about Blazor? Here are the answers that come up again and again.
Blazor is used to build interactive web applications with C# and .NET. Companies use it for internal portals, customer dashboards, administration tools, workflow systems, and data-heavy business interfaces.
Blazor lets teams use C# across much of the application instead of relying mainly on JavaScript or TypeScript. React and Angular have larger frontend ecosystems, while Blazor can reduce language switching for organizations already invested in ASP.NET Core and .NET.
Blazor supports server-side and client-side execution models. Server-based applications keep more processing on the server and communicate over a live connection, while WebAssembly applications run .NET code in the browser and can reduce server interaction after loading.
A strong Blazor specialist usually understands ASP.NET Core, C#, REST APIs, authentication, dependency injection, and database access with tools such as Entity Framework Core. Knowledge of JavaScript interop, accessibility, automated testing, and cloud deployment is also valuable.
The required level depends on the application’s risk and scope, not only its interface. A simple component or prototype may need focused framework knowledge, while a secure enterprise portal calls for a Blazor professional who has handled architecture, performance, testing, deployment, and long-term maintenance.
Yes. Blazor work is well suited to remote collaboration when the team documents component conventions, API contracts, environments, and acceptance criteria. Regular code reviews and shared test pipelines help coordinate specialists across locations and time zones.
Hire a Blazor specialist when an existing .NET team needs frontend capacity, a portal must be modernized, or a project requires a fast transition from prototype to production. Freelancers can also help assess the right hosting model or establish a reusable component foundation.
Ask a Blazor professional to explain rendering choices, state handling, accessibility, authentication, and failure behavior in a previous project. Review component structure, test coverage, browser performance, API boundaries, and documentation rather than judging the interface alone.
The average hourly rate of freelancers who have used Blazor in their recent projects is 88 €, which corresponds to a daily rate of about 702 € based on an 8-hour working day.
