01 / What I do
A good addition
to your team.
From a tricky feature to the next big chapter of your website. I bring hands-on development, a view of the whole system, and a collaborative way of working.
02
Make the next move.
Bring your content into a new home. I untangle legacy structures and build migrations with a clear path from old to new.
03
Connect the pieces.
A strong Drupal backend and a frontend with room to breathe. I build decoupled applications and help the whole stack work together.
How I work
Agentic workflows. Human judgment.
I use a sophisticated agentic workflow with multiple AI models to work more efficiently. The human in the loop is essential. I guide the work from architecture through review and testing.
I’m the architect.
I set the direction and decide how the pieces fit together.
I’m the reviewer.
I review the changes and take responsibility for the code.
I’m the tester.
I test the result against what the project actually needs.

04 / The person behind the name
Hi, I’m Arthur Arthur Lorenz.Friends call me utor.
A developer with deep Drupal roots and a curiosity that rarely stays in one stack.
I’ve spent 9+ years building websites and applications with teams in Vienna and Berlin. Backend development, decoupled frontends, content migrations, and the connections in between.
I like sharing what I know, helping colleagues grow, and finding a better way to get things done. And when an idea won’t leave me alone, I usually end up building it.
“utor” has been my nickname for almost twenty years. Strong, a bit playful, and very much me.
Vienna, AustriaGerman & EnglishOpen-source minded
Good company. In their words.
I wholeheartedly recommend Arthur - he would be an outstanding addition to any team!

drunomics
Fullstack Developer
Back in Vienna 🇦🇹, back at drunomics — building decoupled Drupal applications with Lupus Decoupled Drupal and Nuxt on enterprise scale. I was responsible for the migration of Volkswagen’s Infoportal from its predecessor systems, and on mossbo I drove the brand identity and contributed to product and roadmap decisions. I push for better workflows across the team and naturally mentor junior colleagues.

Backend developer at a warm-hearted Drupal agency rooted in the open source community. I shipped backend work for projects like the World Organization of the Scout Movement and UTBW, and authored a module to detect duplicate images in the media library.

drunomics
Fullstack Developer
My start at drunomics in Vienna 🇦🇹, a Drupal agency specialized on publishers. I grew quickly into frontend, backend and DevOps work and was given the opportunity to take responsibility as tech lead on several projects. The supportive senior team and the Drupal open source ecosystem shaped how I work to this day.
Education
2015 - 2017
App/Web Developer - FH Technikum Wien
A 3-semester academic program covering mobile and web development alongside project management and IT business fundamentals. This is where I picked up the foundations that carried me into my first developer roles.
2012 - 2015
Mathematics - Universität Wien
Three years of higher mathematics sharpened the abstract and logical thinking I rely on every day as a developer. I left the program before completing it once I realized I wanted to build practical things rather than prove them.
