Project details
I provide expert .NET bug fixing, code review, and performance optimization services for ASP.NET Core, C#, Blazor, Web API, and WPF applications. With years of hands-on experience, I rapidly diagnose and resolve complex bugs, memory leaks, concurrency issues, and database bottlenecks.
My code reviews go beyond finding bugs — I identify architectural weaknesses, security vulnerabilities (OWASP Top 10), poor patterns, and scalability issues, delivering a detailed written report with prioritized recommendations.
For performance optimization, I profile your application, identify slow queries, inefficient LINQ, N+1 problems, and memory issues, then apply targeted fixes that measurably improve response time and resource usage.
Every fix includes a clear explanation of the root cause, the solution applied, and how to prevent it in the future. You get clean, maintainable code — not just patches.

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.

Job Success
Lahore, Pakistan - 11:04 pm local time
I build intelligent, production-ready AI solutions and modern cross-platform applications using the full Microsoft .NET ecosystem. Whether you need a custom AI chatbot powered by the OpenAI API, a responsive Blazor WebAssembly web app, a scalable ASP.NET backend, or a native cross-platform app with .NET MAUI, I deliver clean, maintainable code tailored to your business goals.
What I can do for you:
I specialize in integrating the OpenAI API (GPT models, embeddings, function calling, and RAG-based assistants) to create smart chatbots, virtual assistants, and AI-driven automation that genuinely improve user experience. On the development side, I architect high-performance applications with Blazor WebAssembly for rich, interactive front-ends, ASP.NET Core for secure and robust APIs and web services, and .NET MAUI for building single-codebase apps that run seamlessly on Android, iOS, Windows, and macOS.
Why work with me:
I focus on writing efficient, well-structured C# and .NET code, following best practices for performance, security, and scalability. I communicate clearly, meet deadlines, and treat every project from a quick chatbot integration to a full enterprise application with the same commitment to quality. My goal is to turn your idea into a reliable, future-proof product.
If you're looking for a dedicated developer who combines cutting-edge AI integration with deep .NET expertise, let's connect and bring your project to life.
