I will develop a desktop application for windows, macos and linux

Some software still belongs on the desktop: tools that work offline, talk to hardware, crunch large files, or simply need to be fast.

What I build:

• Internal business tools: inventory, billing, reporting, data entry
• Apps that talk to devices over serial or USB, including Arduino and STM32 boards
• Data and file processing tools that need to be fast
• Desktop versions of existing web apps, with offline support

How I build them:

• Rust with Tauri for small, fast apps with a modern UI
• Python with Qt (PyQt or PySide) when you need rich native widgets
• Local database with optional sync to your server
• Installers for Windows (.msi), macOS (.dmg) and Linux (.AppImage)
• Auto-update and code signing when you have the certificates

You get the full source, build scripts and a README, so any developer can pick it up later.

Message me with what the app should do, who uses it and which systems it runs on. I'll reply with an approach and a fixed price.
