I will build a custom qt desktop application for windows or linux
Aria Cheng
About this gig
Need a clean, professional desktop application that actually runs fast and feels native? I build cross-platform GUI tools with Qt 6 and C++17 from data monitoring dashboards to file processing utilities.
Unlike web-based tools, what I deliver runs directly on your machine: no browser, no server, no internet required. Just a fast, reliable executable your team can use immediately.
What I can build for you
- Real-time data visualization: serial port, USB, TCP/IP, or file input
- File management tools: batch rename, move, convert, organize
- Custom dashboards: live charts, gauges, status panels
- Hardware device interfaces: read sensors, log data, export CSV
- Internal utilities: replace the spreadsheet or web tool your team uses with a proper desktop app
- Cross-platform builds: same codebase runs on Windows and Linux
What every delivery includes
- Full C++ source code: CMake build system, works in Qt Creator
- Build instructions: step by step, no guesswork
- Windows executable + windeployqt packaging (if needed)
- Revisions: if it doesn't build or behave as described, I fix it
Not sure if Qt is the right fit for your project? Please message me.

I'm a software developer with 5 years of professional experience and a background in Computer Science and Statistics (B.S. double major + M.Eng. in CS).
Build Qt/C++ cross-platform desktop apps (dashboards, file tools, serial/USB) for Win/Linux/macOS.
Create Python automation: Excel reports, web bots, AI pipelines for hundreds of files.
Freelancing for focused projects outside day job - you get full attention, production code, clear docs, professional communication.
If you have a project in mind, message me before ordering — I'm happy to scope it out and make sure we're a good fit.

FAQ
Do you work with Qt 5 or Qt 6?
I primarily use Qt 6 (6.7+), which is the current long-term support version. If your project requires Qt 5 for compatibility reasons, just mention it — I can target Qt 5 as well.
Can you connect to real hardware — sensors, serial devices, USB?
Yes. The demo uses a built-in virtual signal generator, but I can integrate real QSerialPort reads for any device that communicates over a COM port. For USB HID devices, I can use platform APIs alongside Qt. Share your device's communication spec and I'll confirm feasibility before you order.
Will the application run on my machine without installing Qt?
Yes. I package Windows builds with windeployqt, which bundles all required Qt DLLs. Your end users just run the executable — no Qt installation needed. For Linux I can also provide AppImage packaging on request.
What if I need features beyond the Premium package?
Message me first with your requirements. I provide custom quotes for larger scopes — multi-window applications, plugin systems, database integration, or anything that needs more than a week of work.
Do you provide the source code?
Every package includes the full C++ source code and CMake build files. You own it completely — modify it, extend it, or hand it to your own developers. No obfuscated code, no license restrictions.
