I build production Blazor applications in Radzen. 1,300+ hours across 16 Upwork contracts, and I teach the stack publicly — 400+ tutorial videos and 1,200+ subscribers. Most clients reach me with a Radzen project that is 60% finished and stalled. The scaffolding generated fine, but the business logic, the security model, or the reporting layer will not come together — and the generalist .NET developer they hired did not know Radzen well enough to help. That is the work I do. WHAT I BUILD • Line-of-business web apps — school management, HR, CRM, time and attendance, invoicing, inventory, order entry • Multi-tenant SaaS on Blazor Server, WebAssembly and .NET 8/9/10 Auto render modes • Reporting — PDF generation, Excel export, SQL Server Reporting Services, dashboards • Cross-platform — converting existing Blazor Server apps to Blazor MAUI Hybrid for Android, iOS, Windows and macOS • Data — SQL Server schema design, EF Core, stored procedures, query tuning, migrations RESCUE AND COMPLETION A large share of my contracts are inherited codebases. I take over stalled Radzen and Blazor projects, get them building again, finish what is left, and hand back something your next developer can actually read. If you are not sure whether your project is worth saving, send me the repository and I will tell you honestly before you spend anything. TESTING AND ARCHITECTURE I write bUnit and xUnit tests for Blazor components — most Blazor developers do not — and I structure solutions in Clean Architecture, with the domain kept independent of EF Core and the UI. One client hired me specifically to build the test suite for their Blazor WebAssembly application and wire it into Azure DevOps. TRAINING I also do paid 1:1 and small-team Radzen Blazor training over screen share, from generated scaffolding through custom components, security and reporting. Two of my five-star reviews are for engagements like this. If your in-house team needs to own the codebase after I leave, we can build that into the contract. STACK C# · Blazor (Server, WebAssembly, Auto) · Radzen Blazor Studio and Radzen Blazor Components · .NET 8/9/10 · ASP.NET Core · Entity Framework Core · SQL Server · SSRS · Blazor MAUI Hybrid · Azure · Azure DevOps · Cosmos DB · bUnit · xUnit · JavaScript · HTML5 · CSS HOW I WORK Short sprints, each ending in a demo of running software rather than a status report. I record walkthroughs of what I build, so you can watch me work before you hire me — several are linked in my portfolio below. I am in Lagos (UTC+1): full overlap with European business hours, and mornings for US Eastern. Available 30+ hours per week. Tell me what you are building, or what has gone wrong with what you have, and I will tell you whether I am the right person for it.
