Saad K.

I'm a Senior C#/.NET Desktop Application Developer with over 5 years of software development experience , specializing in WPF (MVVM), WinForms, .NET, SQL Server, and industrial hardware integrations**. I build high-performance, production-ready Windows applications that businesses rely on every day. My primary focus is developing enterprise desktop software with clean architecture, excellent user experience, and reliable performance. One of my key achievements is developing and maintaining a commercial Point of Sale (POS) system that is currently used by 700+ retail stores across the UK. The software integrates seamlessly with a wide range of hardware devices, including CAS, Adam, and Avery scales, Datalogic barcode scanners, receipt printers, cash drawers, customer displays, payment terminals, and other RS-232 and USB COM devices. My expertise includes: * C# / .NET * WPF (MVVM) * WinForms * SQL Server & Entity Framework * REST APIs & SignalR * Azure Services * Multithreading & Background Services * Industrial Hardware Integration * Serial Port (RS-232) & USB COM Communication * Performance Optimization * UI/UX Design for Desktop Applications I enjoy solving complex technical challenges, whether it's improving application performance, integrating hardware, modernizing legacy systems, or building new features from the ground up. My approach is always to understand the business workflow first, identify the root cause, and deliver clean, maintainable solutions rather than temporary fixes. If you're looking for a developer who communicates well, takes ownership of problems, and delivers reliable software built for real-world production environments, I'd be happy to help bring your project to life.
