Hello,
I have 8+ years of experience in Rails and I have installed multiple and configured redmine multiple time.
I also have build custom plugin for redmine for desktop application,which was enabling the company to see the user screen shots under various assigned tasks and Projects.
I am ready to install, configure and deploy the redmine to your server through screen sharing application.
I would suggest you to use free plugins available at redminecrm, they are adequate for small companies.
looking forward for any further queries.
thanks and regard.
