I will fix, debug and optimize your csharp wpf enterprise app and sql database
Hamza
Over deze dienst
I specialize in rescuing, refactoring, and optimizing legacy and modern .NET / WPF desktop applications. Whether your Point-of-Sale (POS) system takes 10 seconds to load a record, or your data grid throws unhandled exceptions, I provide elite-tier technical solutions.
️What I Fix & Deliver:
- C# Codebase Stabilization: Resolving Null Reference exceptions, cross-thread violations, and memory leaks.
- WPF / XAML UI Polish: Unblocking the UI thread (async/await rewrites), fixing broken INotifyPropertyChanged bindings, and smoothing laggy grids.
- SQL Server Database Tuning: Re-indexing tables, rewriting heavy Joins, eliminating deadlocks, and optimizing Stored Procedures.
- Architecture Upgrades: Refactoring "code-behind" into clean MVVM patterns; updating legacy .NET Framework to modern .NET 8.
- Hardware & API Sync: Fixing barcode scanner delays and broken REST API consumers.
Tech Stack: C#, WPF, .NET 8, MS SQL Server, Entity Framework (EF Core), Dapper, LINQ, XAML.
Confidentiality is guaranteed. I am open to working via secure Remote Desktop (AnyDesk/TeamViewer) for strict NDA enterprise environments.
Message me before placing an order. Lets inspect your codebase together!

Veelgestelde vragen
My WPF app freezes completely when fetching data from SQL Server. Can you fix this?
Yes! This happens when heavy database operations are run synchronously on the main UI thread. I will refactor your data access layer using modern async/await patterns so your UI remains silky-smooth and instantly responsive.
Our source code is highly confidential. Can you debug it via AnyDesk / TeamViewer?
Absolutely. I work with many corporate clients under strict NDAs via secure remote desktop sessions (AnyDesk, Zoom, TeamViewer, Microsoft Teams). You don't have to send me your code repository.
Do you optimize raw T-SQL stored procedures as well as Entity Framework / Dapper?
Yes. I analyze SQL Server Execution Plans to add missing Non-Clustered Indexes, resolve parameter sniffing issues, and rewrite slow LINQ-to-Entities queries into high-performance raw Dapper/SQL when necessary.
