Leandro sempre foi muito disponível em ajudar, um excelente profissional, inteiramente dedicado aos projetos que está envolvido. Com grande entendimento das ferramentas utilizadas e uma capacidade extraordinária.

Eu e o Leandro eramos desenvolvedores Front-End na Minuto Seguros. Nosso desafio lá era imenso mas desempenhamos um bom papel. Mesmo com dias pontuais de uma jornada de trabalho excessiva, nunca faltou foco do Leandro e sempre tomou cuidado com a qualidade do código. Não por acaso, as configurações de Lint para checar a qualidade do código foram implementadas por ele neste projeto. Também gostaria de acrescentar que ele manda muito bem no que diz respeito a testes, pois possui um vasto conhecimento sobre esse aspecto e tem o domínio de várias ferramentas que auxiliam toda a equipe e todo o projeto consequentemente. Com certeza trabalharia novamente com ele, pois sem duvida, fomos uma boa dupla.

      It´s a pleasure to work with Ci&T and their co-workers. Very nice environment with true challenges, a lot of fun people and to complete, it's a great place to work ! I worked for the Johnson&Johnson projects, like the general brands of consumer products from USA (Aveeno®, Clean&Clear®, Johnsons Baby®, REACH®, ROC®, Neutrogena® websites, Rogaine®, Ambi Skincare®, Listerine® and Listerine® Kids®, Stayfree®, Carefree®, O.B.® and KY® and a lot of other websites products) and recently with the ACUVUE® Contact Lenses Consumer products. All the projects use technologies like AS2 and AS3, XHTML and CSS, Javascript and jQuery, the backend are not the same almost the time, then I surfed between back ends developed with Java, PHP (Drupal), .NET and Sharepoint and pure XHTML. I have a great experience with SEO, website performance improvements, clean code, accessibility and agility process. Show less
