Kariera is a blog which is a part of the biggest Polish job portal pracuj.pl.

Most of our applications are based on custom tailored code, but Kariera is powered by the old good WordPress platform. We do not reinvent the wheel when suitable solutions are already available. WordPress was not the cure for everything though and the project still had its unique challenges. We had to deal with high web-traffic and provide a few custom extensions by developing own WordPress plugins and customising the theme.
