You will not find a better experience than working with Luiz. We were in a bind because Roku suddenly stopped their Direct Publishing service and he came in and expedited the project, creating a perfect SDK channel for us in no time at all. I had a few tweaks that he quickly was able to go in and change for me and then provide me a few tips for maintaining my channel. If you need a vendor that communicates perfect English (American) then Luiz is your best choice, you will not regret it.
