Bio

Poet, Writer, Project Manager, Mobile Telecom Marketing specialist, Translator, and more… Being Swedish native, I know how to mount furniture from IKEA. 🙂 Oh, and I’m interested in amateur radio, although currently inactive (check your logs from 1980-s for SM0RYB).

The great and versatile tool WordPress can be free thanks to the contributions from thousands of users. And I think it’s great that one can “give back” to WordPress and the community in so many different ways. I’m not a coder (although I may be able to find and fix some small and simple errors in PHP/CSS/JavaScript). But where I really can make a difference, that’s in making WordPress available in Swedish.

Later I even became a global mentor for WordPress translation, so one could say that I support the processes that make WordPress available in more than 70 language versions. Did you know, that 56% (these figures are for June 2023) of all WordPress installations are using a translated version of WordPress? I’m proud to be a part of that!

I was on the organizing team for WordCamp Stockholm 2016, where we successfully introduced the “Micro Sponsor” level for participation.

In June 2023, I was a speaker at WordCamp Europe, with the title: “Enable truly global use of your code – Avoid the typical i18n pitfalls”. It was mainly based on the most important parts of my article about some common i18n-errors developers make: https://gsm.fjellner.com/hints-about-i18n-let-your-code-to-shine-all-over-the-world/

In 2023, I started pursuing ways to drastically improve quality and reuse of content translation for handbooks, documentation, training materials, etc. I’m also on the pilot team for mentoring of new WordPress contributors.

I’d love to contribute more to WordPress, if I just could find the right partners to make it sustainable for me. I want to spend more time on:
– Making it easier for WordPress users to find out about contributing to the project.
– Helping new contributors finding their way in and around the project.
– Re-vitalizing the Swedish community (Yes, I live in Spain, but I’ve got a stable internet connection).
– Encouraging locale teams to publish more relevant content.
– Organizing meetups/WordCamps.
– Smart reuse of translations and content.
– Support for multilingual content in WordPress core.
– … and probably several other things.

WordPress Origin Story

Ended up with WordPress when I wanted to migrate my blog in Russian about working as an expat in Oman to my own domain and made it a tri-lingual site. Since then I’ve helped lots of friends to get started, too.
When I noted that the themes I loved and some plugins I wanted weren’t available in the languages i needed, I started translating them.
Now I’m one of the global mentors for the WordPress translation efforts and an active participant in the Swedish WordPress community, although I live in Barcelona, Spain.

Since April 2025 I’m sponsored 3 hrs per week by Kinsta. Thank you!
Since March 2026, I’m sponsored another 5 hrs per week by Angry Creative. Thank you!
(Happy to discuss more hours/projects with other companies!)
