Adfinem RiskJobs   25 Nov 05
[print link all ]
We release Version 1 of the rails/Ajax app: RiskJobs. It’s written completely in rails. The user profiles get updated using Ajax.

RiskJobs is a German Headhunting website for the Risk Management domain. Applicants can fill out their profiles (tree structures) and companies can search: e.g. we need an operational risk expert with 3 years of experience that also knows X, Y and Z.

This adds one more app, the ever growing RealWorldUsage wiki page.
