Dear Sir/Madam,
I have written a price and due time, however, it will depend on the project length and requirements. With regards to myself, I am a Uruguayan Software Engineer, with basic Portuguese language knowledge, who has worked on android development for the last 4 years in the most important public transport company in my country. I also passed my android-based graduate thesis with 98%, in which I developed the 100% of the mobile application and I was the Project Manager.
If you would like me to help you with the project, we can discuss the details.
Kind regards
