About Robert

Robert H.Status: Offline
Senior C#/.NET Developer | API Bug Fixes | .NET 10 Upgrades | Azure
Sutton Coldfield, United Kingdom - 2:28 am local time
Need fast help? I offer fixed‑price projects for .NET API fixes, .NET upgrades, and performance diagnosis — see my Project Catalog for details.

I help companies fix broken APIs, speed up slow backend services, and modernise legacy .NET systems. Most clients hire me when they need a fast, reliable fix — not a long onboarding process.

If your API is failing, your .NET service is slow, or your migration to .NET 6–10 is stuck, I can diagnose the issue quickly and deliver a clean, maintainable solution.

What I deliver
• Fix API errors, exceptions, and broken endpoints
• Diagnose and resolve performance bottlenecks
• Upgrade .NET Framework to .NET 6–10
• Build or fix Azure Functions, App Services, queues
• Create or repair API integrations
• Debug production issues and reliability problems

Why clients hire me
• Fast diagnosis (usually within 1–2 hours)
• Clear explanations and actionable fixes
• Clean, maintainable code
• No hand‑holding required
• Async‑friendly communication

Tech stack
C# / .NET 6–10, REST APIs, Azure Functions, App Services, SQL Server, EF Core, Clean Architecture, Microservices, CI/CD.
