Luís Ferreira

Luis is a master of his craft; you won't go wrong by hiring him.

Good god this guy knows what he's doing. Period.

Excellent! Luis can find a needle in a haystack and super fast.

Makes it fun. He not only helped with my task, but helped me understand what he was doing so I could better help myself in our next session or on my own going forward. Highly recommend zamith!

I had been trying for days to solve the problem by doing something irrelevant and he noticed the basic problem just like a snap. I'm very satisfied with the session with him.

He helped me out when I really needed it! Great job and I got the result I wanted! Also verry informative. I am new in CSS but I understood everything.

Luiz is very efficient. We were able to dive in the code straight away and got some Rspec test passed very quickly.

Luis was very helpful in walking through some very complex code with me and explaining how to improve it. While it was a large app, he very quickly was able to understand what was going on and was able to not only explain the possible decisions behind the way it was architected, but also best practices to improve it.

long-term mentoring

very helpful to fix some Rails assets
