we are looking for an experienced Qt/KDE developer to implement two really small desktop utilities for us as paid projects.
Both applications already exist in a similar form for windows, so the required functionality is quite clearly defined. We can provide detailed descriptions and screenshots of the existing applications.
The two projects are:
1. PDF-Encrypt
A small utility for encrypting PDF files.
The application should have a simple GUI and support drag & drop.
2. BulkFileChanger
A utility for changing file timestamps of multiple files.
Again, the functionality is based on an existing application (BulkFileChanger) for windows and is already documented in some detail.
General requirements
The applications should:
run on Linux with KDE Plasma
be written using Qt
integrate well with KDE Plasma/Dolphin
have a clean and simple user interface
be easy to deploy and maintain
This is paid work.
We are a small German management consulting firm working primarily with owner-managed small and medium-sized businesses. We help our clients improve their financial performance and make better business decisions, with a particular focus on financial planning, controlling, financing, investments and business succession.
We are looking for someone who can implement both utilities and ideally also maintain or extend them later if necessary. At this stage, I would mainly like to find out whether someone in the KDE/Qt community would be interested in taking on these projects.
If you are interested, please contact me. I can then provide the detailed specifications and screenshots for both applications.
These are really just two small utilities with a very limited and clearly defined set of features.
And definitely FOSS. I’ve been a Linux user since 1999, so naturally I’d much rather sponsor the development of free and open-source software than pay for proprietary software.
My intention would be to fund the development and make the resulting software available to everyone under an appropriate open-source license. I don’t need or want to own the software as proprietary IP.
Yes, I know. The problem is that my employees simply want a graphical user interface. They all grew up in the Windows world and are used to doing these kinds of things with a GUI rather than on the command line.
So the point of the utility isn’t that the functionality doesn’t already exist on Linux – it’s about making it easily accessible to non-technical users.
Hello, I’m a Python/Qt developer who has made various applications available as open source. I create them to solve specific tasks I need, always prioritizing privacy and local processing. You can view my repositories under “safetoolhub” on github. safetoolhub org is the landing page for all of them.
Have a look for example to Safetool-Pix, which was the first application I made available to the general public as an example of my work. However, these are not well-known applications because I create them to address my specific needs, and I share them with the community in case anyone would like to contribute or adapt them to their own needs. As long as your applications end being Open Source we could collaborate if you want
Sorry for the delay in getting back to you. We had a public holiday, so today is my first day back in the office. Thank you for your reply.
I would love to exchange ideas with you, especially regarding BulkFileChanger.
Please forgive the silly question—I’m not part of a developer community: How and through which channel do we usually communicate? What’s the best way to reach you?
Hi Markus, I’m interested in taking on both small FOSS Qt/KDE utilities. I can review the detailed requirements and screenshots, then propose a focused implementation plan and realistic estimate for the PDF encryption tool and Dolphin-integrated timestamp editor. Please let me know whether the work is still available and share the expected budget and timeline. Best regards, Dmitry
Thank you for your reply. I’m really happy to hear that you’d like to take on this project with us. I’m currently out of the office on holiday until October 5th, 2026. I will get back to you as soon as I return.
The problem is that my employees simply want a graphical user interface. They all grew up in the Windows world and are used to doing these kinds of things with a GUI rather than on the command line.
