“The price of success is hard work, dedication to the job at hand, and the determination that whether we win or lose, we have applied the best of ourselves to the task at hand.” – Vince Lombardi.

Codeable Certificate

I am a senior full-stack developer living in Valencia (Spain) but working internationally in a remote way.

About Me

I have been working as a web developer since 2002 but was in 2013 when I started working almost exclusively with WordPress. In this time, I have had the opportunity to create many diverse things for my clients (from simple customizations to complex integrations or complete websites from scratch) and have achieved a great deal of experience in all aspects related to WordPress developments.

Three years ago, I decided to create my own web agency (Be Rebel) and since then, we have grown to a team of 6 persons: 3 full-stack developers (specialized in WordPress), 1 PWA/Mobile APPs developer, 1 graphic designer (specialized in UI/UX) and 1 digital marketing and SEO/SEM specialist.

Quality of Service

I focus my efforts on providing the best quality software to all my clients. These are some of the key-rules which are regularly applied to my projects:

  • Always following standards. No matter the technology used, it is important to follow the standards. That is why I use code quality tools like PHPCS (PHP Code Sniffer), WPCS (WordPress Coding Standards), PSR (PHP standards recommendations), ESLint (Javascript Linter) amongst others in all my developments.
  • Deadlines. For the client, fitting to the deadlines is a top priority. This is why I take this seriously and, if needed, I will involve other members of my team to deliver my projects in time (or even sooner), so as not to cause any inconvenience, so as to comply with the client’s expectations.
  • Using good practices. In order to deliver the maximum quality, I use the best development practices for all programming languages: object-oriented approach, MVC schemes, modular architecture, design patterns, TDD (test-driven development), etc.
  • With modern technologies. I love to recycle myself with all new trends, pioneer technologies and newly-created methodologies. Things like SPAs (single-page applications), CSS BEM (Block Element Modifier), hybrid mobile APPs, CSS pre-processors (SASS, LESS), package managers (npm, Yarn, Composer), task runners (Gulp, Grunt, npm scripts), Bundlers (Webpack, Parcel), REST APIs, javascript frameworks (Angular, Vue, React) are part of my day-to-day toolset.
  • Well commented code. It is important to document all the code. Perhaps in a future, we will have to go back to a code developed some years ago thus being very useful to have a short explanation of what that code does, instead of having to dig into the code to understand what is doing. Besides, if it is another developer who has to retake the code, this can help him/her to understand it, so as the developer can focus in what is more important (the changes/improvements requested to him/her). For that, I use in-line comments, PHPDoc blocks and JSDoc blocks.
  • Bearing UI/UX in mind. The look and feel of any website or application are very important to attract and maintain the users base, so I love to design attractive user interfaces but always bearing the user’s experience in mind. Tools like Zeplin and Invision, help me to share the designs with clients for approval/remarks.
  • Performance as a must. While developing, is important to take care of any repetitive or time-consuming processes that could affect the overall performance and at the worst, could take down the site. This is why the best good practices to maximize the performance are used: transients, caching, auto-loader, loading scripts only when necessary, file minification, etc.
  • Organized-working. It is important for the health of any project with this aim. I use a Git repository for all my projects so as to track all the changes made and to be able to go back to a previous state when necessary and also use project management tools like JIRA or Trello, which help for the project organization and to show the client the stage and the progress of each task at anytime.
  • GDPR fulfilment. On May 25 2018, the European Union approved new rules for the GPDR (General Data Protection Regulation) law, affecting all the software potentially used by anyone within the EU. Before that date, WordPress and WooCommerce (amongst others), hastened to launch new versions pretending to minimize the transition to the fulfilment of the new regulation. The new features added to WordPress core helped a lot, but are not the only things that must be considered while developing a new website.
    Thus, as part of my quality of service, I take care of these requirements and the client can be even-minded being in-line with the accomplishment of the actual regulations.

Also, as a team, we can handle all kind of project sizes. The short-ones can be handled by myself and, for more complex projects, other team members can be involved too in order to meet your deadlines.
