Luiz was a key contributor to Experiment Engine’s success. He is an extremely motivated, intelligent worker, who learns quickly, and is able to generate creative solutions to difficult problems. At Experiment Engine, he managed a wide range of clients in an extremely fast paced environment with impeccable quality and optimization results.

Luiz is an excellent communicator and a very resourceful contact. Luiz helped my company, Insightly, A/B test and personalize our website, and in the process, increased our product trial signups and reduced our bounce rate. He was always thorough and prepared in our meetings, and always knew what we wanted before we wanted it. Despite being two time zones away, Luiz was like having an in-office help resource at our beck and call. I sincerely hope our paths cross again.
