ABOUT ME
I've been developing web applications for some years now, mostly using Ruby and Ruby on Rails. On top of that I have taught web technologies to hundreds of people, through workshops, bootcamps and university classes.
Gigs

I'll create a base rails app that has some of the most widely used gems and configuration done for testing with RSpec and Capybara.

I will build a chat app without any styling, but with authentication and multiple rooms the users can talk at.

We will go over your pains with git and working with it by yourself or as a team, and how you can overcome your fears and embrace git as the awesome tool it is.

I will integrate your app with Stripe checkout, using Stripe.js so that the credit card info never touches your server. I will create a form for the info, or add to an existing one, that people can use to pay you for something with a specified price. Alternative: Use the form to create a subscription to one plan.

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.
Sindre Olsson May 30, 2016

Luiz is very efficient. We were able to dive in the code straight away and got some Rspec test passed very quickly.
Michael Cho May 30, 2016

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.

Very efficient and effective codementor. More than I dreamed of.
Miriam Sep 05, 2015

Luis was very helpful and listened as I explained where I thought my skill level was and where I felt I needed help with. After a few exercises, he provided his assessment of my abilities (which I felt was constructive) which helped in my understanding of what I needed to concentrate on in building my skills. I highly recommend Luis and will request his help again.
