Looking for a Qt/KDE developer for two small paid utility projects

Hi,

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.

Best regards,
Markus

Do you mean you would sponsor the development of them as FOSS, or pay a developer to produce something that becomes your proprietary IP?

You could use the command line touch command to do this.

See man touch and its -t and -d options.

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. :slight_smile: 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.

Do you mean encrypting or digitally-signing or both ?

The main integration point I can see would be context menu actions.
Either service menu or KAbstractFileItemActionPlugin Class | KIO

pdf chain does this with two different forms of encryption

KRename does this with a plugin

either or both of these could be added to a service menu for right click access in dolphin or from the desktop.

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 :wink:

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?

Kind regards, Markus

For now, encryption would be enough for me.

please send me an email to safetoolhub@protonmail.com and we’ll continue from there :wink:

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

Myself Ansif from Kerala. I am a software programmer experienced with C++/Qt and KDE desktop development. I saw your post on the KDE forum about the two small utilities — PDF-Encrypt and BulkFileChanger — and the FOSS sponsorship model. Will it be possible to support you remotely? I’d be happy to discuss the specifications and provide a plan for both utilities
