WordPress and WooCommerce websites (recent)

• In October 2021, I took over the maintenance of myLAB Box for XWP. myLAB Box is a WooCommerce site hosted on WordPress VIP. In addition to maintenance and adding features as requested, I have focused on performance and security.
• In 2021 I rebuilt the website of Bohlin Cywinski Jackson, an American architectural firm, based on the existing design and using WordPress, custom post types, custom taxonomies and custom fields. I also built a subsidiary mini-site for Bohlin Cywinski Jackson using Next.js and the GraphQL API.
• In 2019 I completed the new website of NOMIS Foundation, a Swiss private fund for scientific research. The site uses custom post types, custom fields and automatic bi-directional post-to-post relationships, it integrates third-party libraries like Siema, baguetteBox.js, and schema-org and has a members area implemented with BuddyPress. I maintained the NOMIS website on a Linode VPS from 2017 to 2020.

WordPress and Timber

I have built a handful of sites using Timber. Timber is not for all WordPress projects, but I find it a pleasure to work with when it fits the task.

Skills, continued

HTML, CSS and Sass

I have explored and used semantic HTML and standards-compliant CSS since 2002. I always aim to use the latest HTML and CSS features supported by targeted browsers; this brings benefits in performance, accessibility and SEO, while it is also something I enjoy as a developer.

Most of the CSS I have written since 2012 is in Sass (SCSS). As CSS gets new and powerful features, lately I have started using plain CSS in some projects. For complex projects, I still prefer Sass.

JavaScript and TypeScript

I started using TypeScript in 2016. I like TypeScript because it helps me undertand how JavaScript works. About half of JavaScript I write these days is in TypeScript.

PHP

I follow the developments in PHP and I strive to follow modern practices and to take advantage of modern features available in the PHP ecosystem and in the latest versions of the language.

Astro

Astro is currently (2024) my static-site generator of choice. It offers the best developer experience out of all the SSGs I’ve used.

React & Next.js

I have built a couple of simple WordPress front-ends using Next.js. I also use React for custom Gutenberg blocks in WordPress.

Git

I have used Git since 2009. I also have experience with Subversion and Mercurial.

Gulp, webpack, Vite

Vite is my current bundler and dev server of choice. I also have experience with webpack and Gulp.

Linux administration

I have used Debian and Ubuntu since 2003 both on the command line and through a graphical interface. I maintain a few Debian servers at Linode for hosting, testing and web development.
