Azure Developer Needed
Muhammad did a great job of bringing my vision to life for my virtual classroom environment. He communicates well, is professional, punctual and kept his word. He kept me apprised of challenges, took the initiative to solve them, and let me know which roadblocks he needed my assistance with, etc. He kept the project moving along in a timely manner. It was an absolute joy to work with him. I look forward to hiring him for future projects. I will gladly recommend him to others, as appropriate.

I specialize in secure, scalable, and maintainable .NET systems — from RAG-based AI assistants and AI agent workflows to multi-tenant Blazor SaaS apps, Blazor Hybrid mobile/desktop apps, enterprise APIs, Microsoft Entra ID authentication, microservices, and legacy .NET modernization.
6+ years of senior .NET experience delivering production AI, Blazor, and enterprise architecture for teams that need senior judgment, not just code.

.NET Modernization
• .NET Framework to .NET 8 / .NET 10 migration
• ASP.NET / Web Forms modernization
• Legacy architecture cleanup
• Monolith to modular architecture
• Performance, security, and maintainability improvements
A few examples of my work:
• Built a multi-tenant AI Sales Platform using .NET 10, Blazor WebAssembly + Server, MudBlazor, Azure, .NET Aspire, GitHub pipelines, and Microsoft Entra External Identities.
• Built a RAG-based AI Assistant with .NET 8, Azure, Azure OpenAI, React, and role-based access control.
• Built enterprise case management platforms using C#, .NET 8, Azure, SQL Server, and microservices.
• Built a Blazor Hybrid / .NET MAUI mobile app used by 9,000+ Android and iOS users.
• Built AI-powered document and check analysis workflows using .NET, React, Power Automate, and third-party integrations.
• Designed secure enterprise systems using Microsoft Entra ID, OAuth, OIDC, JWT, MFA, and RBAC.
My focus is not just writing code — I help clients make the right technical decisions, reduce complexity, and build systems that can scale.
