A conclusion

I have some doubts about how to explain a conclusion. I'm not sure about some of the words.

Can you help me?

Teamwork is difficult when the team doesn't have a good relationship because the members does not have the confidence to explain their doubts. I think our team has a good relationship, I liked working with each of the members. With lots of laughs, scoldings and help, we have worked a lot to develop this project.
Working with the Android platform was interesting because we developed an app and we've learned much.

P.S. If you want to improve your Spanish skills, send me a message. I could help you.
