I worked with Rafael at BrightHR in my role as website manager. I had to frequently liaise with the Mobile team and often Rafael to receive the latest information, features and releases to promote them and co-ordinate with the wider marketing team.
He communicated clearly and has the ability to truly understand the audience he is talking to, which other developers often lack. I am not an expert in mobile development but I am aware he was highly regarded at BrightHR in his specialist Android role.
I was often apart of stand ups and demos where Rafael presented in front of a variety of stakeholders and he was always professional and confident.
I would highly recommend Rafael for a variety of mobile development roles and I would very much like to work with him in the future.
