About this gig
Are you looking for someone to build a desktop or cross platform app that actually works the way you need it to?
I can help you develop a custom application for Windows, macOS, Linux, Android, or iOS. I been developing software for the past 4years and have worked on different types of projects, including POS systems, healthcare apps, scheduling software, manufacturing tools, hardware integrations, AI powered desktop applications, and custom business software.
I can also work on an existing application if you need bugs fixed, new features added, performance improved, or an old project updated.
Depending on your project, I can use WPF, WinForms, WinUI, .NET MAUI, Tauri, Electron, React, Vue, Svelte, PyQt, Qt, or Kivy.
My main programming languages are;
C#
JavaScript / TypeScript
Python
You will receive the source code and the required application build/installer, so you have full control of your project.
If you already have a website or an application created with another developer or an AI tool and need it fixed or converted into a desktop or cross platform application, I can help with that too.
Send me a message with your idea or requirements, and we can discuss.
