Paulo is an awesome mentor! I am looking for projects so that I can keep getting mentored by him. Very responsive & really puts in the effort whether it is online research or talking to others within the community to help find a solution. I would give 10stars out of 5 :)

Paulo is an excellent mentor. I would rate him 10 stars. His grasp at the fundamentals are very strong & he really helped me getting the right structure & tech-stack for the app I am building. He actually goes out, talks to people to clear any doubts. I totally recommend him.
