Let me talk a bit about some of the skills helped and still help me on a day to day basis.

Programming Languages

These are the programming languages that I am most comfortable with (so far ☺):

  • ECMAScript
  • TypeScript
  • PHP
  • Ruby
  • C
  • Shell Script

And these are the ones I have some knowledge about, have done some toy projects or otherwise studied a good deal about them:

  • Racket
  • Scheme
  • Common Lisp
  • Haskell
  • Java

Some front-end technologies I have worked with for a long time:

  • Vue.js
  • React
  • HTML and CSS1
  • Sass
  • PostCSS
  • jQuery
  • Bootstrap
  • Bulma
  • Responsive layouts (with or without ready-made frameworks)

Frameworks (back-end)

I have reasonable experience with:

  • Ruby on Rails
  • Laravel
  • Symfony
  • Node.js
  • Express

Source Code Management

  • Git
  • Github
  • Bitbucket
  • Gitlab


  • General SQL.
  • MySQL / MariaDB.
  • Postgresql.

And I do know how to use them from the command line as well. I mean, if there is a GUI tool, great! If there is not, I know my way around anyway.

Shell Script and Command Line in General

  • Shell Script2
  • Tools like sed, grep, find, cut, and almost all other useful command line programs that one may want and need to use on a *nix system


Those who have worked with me know that I am crazy about self-documenting code and code documentation in the form of comments. I love to have a well written and concise code doc in functions and methods explainng what it does, the parameters accepted, default parameters, what it returns, what is assumed, etc. I also like to write about documentation :).

Other Experience and Tools

  • Deploy and maintain Rails apps on Heroku
  • Use third-party APIs like Cloudinary and Postmark in Rails
  • TDD
  • i18n, mostly in Rails and Jekyll

Some projects

  • A bunch of small to medium web systems to solve particular business requirements for different clients, for instance:
  • a CMS manage web sites, and a module to manage real state
  • a system to manage products (prices, stock, etc.)
  • a system to manage clients and documents
  • sites with shopping carts, user registration, etc.

  • A bunch of web sites
  • HTML/JavaScript audio player that runs in the browser
  • PHP router that I used in some of my side-projects
  • A Vim ftp plugin that helped me in a past job :)

1 Yeah, I know many do no consider this real programming, but it is part of the game nonetheless.

2 I do create scripts to help me with a lot of things like automating tasks, backups, etc.
