Posso destacar aqui várias qualidades no profissional Rafael Bessa, entre elas: foco no resultado, organização, busca contínua pelo conhecimento e atitude de dono. Participou de grandes entregas na área de planejamento e controle, automatizando processos que consumiam boa parte do tempo dos analistas, onde como resultado foi possível aumentar a eficiência analítica da área.
