I will build a desktop app in c sharp, c plus plus and python
Zakhar Vlasenko
About this gig
Need a desktop program built from scratch, or an existing one fixed? I write desktop software in C#, C++ and Python, from small one-window utilities to full applications with a database and an installer.
What I can build for you:
- Business tools: inventory, invoicing, simple CRM, reports and exports
- - Utilities and automation for files, Excel, PDFs and repetitive tasks
- - A GUI for a script you already use
- - Apps that connect to an API, a database or a device (serial/USB)
- - Bug fixes and new features in your current C#, C++ or Python code
My stack:
C#: .NET 8, WPF, WinForms, MAUI, Entity Framework
C++: C++17/20, Qt, Win32 API, CMake
Python: PyQt/PySide, Tkinter, pandas, PyInstaller
Databases: SQLite, SQL Server, MySQL, PostgreSQL
Also: Unity, Unreal Engine, OpenAI API, Git
Please message me before ordering. Tell me what the app should do and I'll suggest the language and the package that fit.

FAQ
Which language should I choose for my app?
If you're not sure, tell me what the app has to do and where it will run. I usually suggest C# with WPF for Windows business tools, C++ when speed or hardware access matters, and Python for quick tools and data work.
Do I get the source code?
Yes. Every package includes the full source code with comments, plus a compiled build or installer so you can run the app right away.
Can you fix or add features to my existing program?
Yes. Send me the code or a repo link and describe the problem. I'll look at it and tell you which package fits before you order.
Will the app work on Mac or Linux?
WPF and WinForms apps run on Windows only. If you need macOS or Linux too, I can build it with Qt (C++), PySide/PyQt (Python) or .NET MAUI. Tell me before ordering so we pick the right one.
What do you need from me to start?
A short description of what the app should do, screenshots or sketches of how it should look (if you have them), sample data or files, and access details for any API or database it has to use.
Do you offer support after delivery?
Yes. If you find a bug in what I delivered, I fix it for free: 7 days after delivery for Basic and Standard, 14 days for Premium. New features after that are a separate order.
