The team have stuck with him and he drove his best race of the season so far in Monaco, finishing 12th.
Now, De Vries is looking forward to the Spanish Grand Prix and exclusively told GPFans that he is hoping for a top-ten push.
"I do have the feeling that we are getting closer and closer to the top ten," he said. I hope this can give us an extra push.
"In terms of expectations, I don't think it is much different than all other weekends. It would be nice if we could be back in Q2 with both cars and be close to that top ten to take advantage of other people's mistakes or do it on our own merits."
AlphaTauri have only managed to score two points so far this season with Yuki Tsunoda finishing tenth in both the Australian and Azerbaijan Grands Prix.
With the more experienced Pierre Gasly leaving for Alpine in the summer, AlphaTauri moved to sign De Vries, partly on the back of an impressive points-scoring debut with Williams last year as he filled in for Alex Albon at the Italian Grand Prix.
It has not been an easy transition into F1 full-time for De Vries but things are looking up after his 12th-place finish on the street circuit.
The result prompted Red Bull advisor Helmut Marko to publicly praise the sister team driver but De Vries says he does not want to get too carried away.
"I try to focus on that and hopefully I can do that as best as I can and mean the best for the team," he added. "Of course it's nice to hear, but it's about what we show on the track."
