Trying to post freelance opening on jobs board

I'm trying to create an account to post a freelance opportunity on the OutSystems jobs board, but I'm unable to create an account.  I keep getting the message "timeout-or-duplicate".  

I'm looking for someone who can create an OutSystems mobile plugin that will work in Android and iOS for the Jitsi Meet Mobile SDK (see; ).  Jitsi Meet is a popular open source videochat tool that is developed in partnership with Atlassian.  

 I'm doing development in OutSystems, but I don't have the experience to create this plugin.  If you are able to help, please contact me.  Thank you!
