The 22-year-old made 35 appearances for the Giallorossi after joining from Corinthians in July 2012, with the San Siro outfit prompted to secure an initial €1.2 million deal for his loan and an option to make the move permanent for €9m.
Dodo has represented Brazil both at Under-17 and Ur-20 level and he feels joining the Nerazzurri will bring him a step closer to his first senior cap.
"Inter presented me with a project which I can be more involved in," the youngster told Corriere dello Sport.
"After call-ups with the U-17 and U-20 sides, I am convinced that Inter will give me the push to get into the national team.
"I was pleased that, after being with Roma for two years, a team like Inter thought me so important. Together with my agent we realised that this was the best option for me and here I am."Inter finished fifth in Serie A last term but Dodo belives that, under the ownership of Erick Thohir and with Walter Mazzarri in charge, the club offer an environment for him to develop and win silverware.
"The conditions are good [for me] because Mazzarri gives great importance to the development of the game on the flanks," the left-back added.
"I was aware of this reputation of our coach and I had no doubts. This is an important project, in the next few years it is expected that the team will be reinforced with new purchases and youth development.
"Thohir said the goal is to win the championship in the next few years. Our goal is to better last year in the league and play well in Europe.
"I want to achieve the goals the club has set and play as much as possible."
