We have a device that updates its firmware remotely via a Windows application.
Clients connect their device to the computer via a USB cable and when the update process starts, it connects to our server, from where it gets the latest firmware.
The Windows application that the client uses has been developed in Visual C++ / MFC, while the backend server application is in Ruby on Rails.
This development is about 10 years old, it was working well until now, but for some reason the update process has started to fail.
Scope of work:
Your role will be to debug the Windows application and see what is preventing it from getting and applying updates to end-user devices. Hopefully this will be a good starting point to help solve the problem.
Important Note:
If you have read this far, it is probably because you are interested in applying for this job. That's why I ask you to write the following code: RUBYONRAILS2024 in the first line of your proposal. Proposals that do not meet this simple requirement will be automatically discarded.
Looking forward to finding the right candidate for this project!
