I had the pleasure of working with Leandro in many projects for some of my clients. He is very proficient in his field as an iOS developer, has great communication skills and proactive attitude and delivers things on time and with great quality. He also was a very valuable help for project estimations and leading other developers to fulfill some requirements for the projects. When I need an iOS developer or someone ask me for a referral on this skill, Leandro is the first person I think of. As a team member or a leader, Leandro earns my highest recommendation.
