About Juan Cruz

In my professional life, I face challenging projects with enthusiasm; I firmly believe that teams work better if they work in trust, appealing to good relationships to achieve the objectives. Cooperating to achieve goals, pushing everyone to the same side, giving and receiving support, and above all, thinking that every problem has a solution.

Given my background as a developer, and the knowledge in systems design acquired in my career, I strongly believe that logic overcomes any problem, solving them either by focusing on the critical points and attacking them or by thinking outside the box.

I am constantly looking for self-improvement and I am continually discovering things I would like to learn. Proactive and convinced that there is always room for improvement.
