Technical Support Specialist for Software Development Team
I hired Muhammad to investigate a complex technical limitation we were facing with DevExpress reporting, specifically to confirm whether the VS Code extension's inability to handle .cs files was intended behavior or an issue with our setup.
Muhammad's performance was nothing short of amazing.
He was incredibly fast, professional, and demonstrated an immediate and deep understanding of the entire .NET and DevExpress ecosystem. He didn't just provide a simple confirmation; he delivered a thorough, well-researched analysis that explained why this limitation exists, detailing the architectural differences between Visual Studio and VS Code, and how the VS Code extension is specifically designed to work with .repx files.
His clear, detailed, and confident explanation saved us an immense amount of time and resources we would have otherwise spent trying to debug a "problem" that was actually a core design feature.
If you have a complex .NET or DevExpress issue, hire Muhammad. His expertise is exceptional, and he delivers high-quality, actionable answers. 5 stars, without a doubt.

It breaks because the architecture becomes messy, performance slows down, bugs pile up, and nobody wants to touch the code anymore.
If your ASP.NET application is becoming difficult to maintain, scale, or improve, the problem usually starts much deeper than the user interface.
