ABOUT ME
Full-Stack Software Engineer
Full-Stack Software Engineer
I'm a Costa Rican software developer specializing in e-commerce, with a passion for building systems, learning new things and helping others do the same.
I'm currently certified for the Magento platform as an Adobe Commerce Developer and as an Adobe Front End Developer, and I have expertise in the related technology stack: PHP, Apache/Nginx, MySQL, Linux, JavaScript, CSS and HTML. I've also worked with Laravel (a platform that I particularly enjoy) and WordPress.
My previous experience and training as a data engineer using SQL Server and as a Java/.NET developer, allows me to build better web applications. I have a passion for systems design and software architecture, and have a special interest in the problems that begin to appear once we need to support a global scale.
I believe that technology can be a huge benefit for our lives and our societies. But it should be deployed responsibly, both from the technical point of view (following good practices is a critical aspect of our work as engineers) and from the social point of view. The decisions of a team of developers that care about their work can make a big difference for a lot of people.

I've worked professionally with Linux since 2003, when I was involved in creating a special distro for a telecom project. After I finished that project, I continued using the platform for my main web development and system administration work.
Linux is my main platform right now for development. I use an Ubuntu 16.04 laptop, and I have another computer with a more recent Ubuntu 18.04 distribution setup. I also work with CentOS and Amazon Linux servers on a regular basis.

PHP has been my main language since 2005. This is the base for popular CMS platforms, such as WordPress or Drupal, and also the well known e-commerce such as Magento.
PHP can be used for good, or abused. The second option can give you many headaches! So good programming practices are recommended, even if it was initially just a scripting language.

I've been working with HTML and CSS since I started doing web professional work in 2002. CSS in particular used to require a lot of tricks to be done properly. More recently, expanded browser support means that things are generally simpler. However, it's important to know the background and details to save time and create more robust websites.

Most of my experience in web also involves working with JavaScript, the ubiquitous language for browsers. I remember when people used to confuse it with Java... and they keep doing it some times.
I can help with browser based JavaScript problems, with jQuery integrations and other features for the front-end.
