(Portuguese app) React Native App Development with Firebase Integration
Michel is truly a gem on Upwork. Very skilled technically, but what really stands out is how well he understands the product side as well, not only development itself.
He understands the process from end to end, is always available when needed, and constantly brings constructive and thoughtful ideas to improve things. Communication is easy, he is proactive, responsible, and someone you can truly trust with a project.
Besides being a great developer, he is also very professional and pleasant to work with. I definitely recommend him.
