Project History
Melollevo
Melollevo is an auctions site that operates in Colombia. I developed it all in Ruby on Rails with some jQuery and PostgreSQL as the DB. I built the entire site, including the design (except for the logo).
Melikeu
Melikeu is a brand new dating website that helps users discover if the person they like, likes them too. The site is developed in Ruby on Rails with some jQuery and PostgreSQL as the DB. I developed all of the backend and part of the frontend.
Awesome checkbox
Awesome checkbox is a JS/CSS plugin that has been extremely useful in many projects I've worked on that allows to easily style checkboxes using font-awesome (or any custom css class), so it basically replaces the default checkbox for any two icons with custom size, color, etc.
