Crossjoin Clients and Success Stories

“

We were having sporadic performance issues and we were struggling to understand the cause. In a very short period, Crossjoin identified the root cause and proposed a simple but very effective correction plan. Since then, we trust Crossjoin to help us on complex infrastructure related issues and we are very happy with this partnership.

“

We have worked together since 2008 in a collaborative team work, that is focused on systems performance and tuning. Since then, we have achieved quite good results

José RuivoDirector – PT Inovação
“

Crossjoin improved he E2E billing chain from 50 hours down to 12 hours. After the big achievement on the Hallo project, back in 2009, and this one during 2011, Crossjoin has exceeded all expectations.

SabineIT Manager at Telenet NV
“

I strongly recommend Crossjoin as a company specialized in performance issues. In our area, they managed to increase the performance of the GLX/JSP flow from more than 24 hours (best time obtained by our off shore delivery team) to only 1,30 hour!!
