In particular, I have adopted techniques of:

Processing extensive data coming from various sources in distinct formats.

Presenting data along with the most powerful analytic tools.

​Having gained all the valuable expertise in the field I had decided to quit a "big corporation" life and I started to provide my own consultancy and services.
