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!!

… in IT projects, especially in the field of IS / IT Telco’s with technology and more complex business development and with the need to respond to new monthly challenges. The metaphor of Adam Smith “invisible hand” is represented by Crossjoin and managed by João Modesto and Rodrigo Garcia with their IT skills in Tuning and Performance Systems.

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.

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.

Unparalleled experience and mastery in RDBMS accompanied by a proactive spirit in problem-solving.

Crossjoin has excelled in the services and the guarantee they offer to Vodafone UK, the CJ staff has been very proactive, as well as the support in any incident. All of his staff have demonstrated excellent technical aptitude and have managed to analyze and solve innumerable problems, both in the performance of the database and in the applications.

Company with top professionals specialized in performance optimization, providing an high quality service and support whenever it is necessary.

Crossjoin has become a partner of great importance that accompanies us in our day to day always seeking to provide value to the services that we provide the business.
