Lucas Dohmen

You can read some of my words on Mastodon and some of my code on Codeberg. I'm fluent in both English and German.

Work Experience

When I finished school in 2007, I started working part-time (first during my civil service and then while studying). Since I started working on my master thesis in 2014 I am working full-time.

Team Lead

komoot GmbH

From 09/2023

I am the team lead for the Web client of Komoot, an application that helps you plan and navigate your hiking and biking trips.

Consultant / Senior Consultant

innoQ Deutschland GmbH

04/2015 - 08/2023

I worked on the architecture, conception, and implementation of web applications on the front and back end. I coded in Ruby and JavaScript, helped with technology decisions, and gave trainings on Web architecture and JavaScript.

Developer

ArangoDB GmbH (previously known as triAGENS GmbH)

04/2012 - 03/2015

As a member of the core team of ArangoDB – an open source NoSQL database – I worked on the Ruby driver family, designed and implemented most of the Foxx Web API Framework and developed parts of the graph functionality.

Prior to that

• 11/2010 - 02/2012: Research Assistant and Developer at RWTH Aachen: Chair of Computer Science 5 (Information Systems)
• 03/2010 - 10/2010: Rails and Frontend Developer at VerkehrsmittelVergleich.de
• 07/2007 - 03/2010: Frontend Developer at netSkill AG

Programming Languages

• Ruby
• JavaScript/TypeScript (Node, Browser or Deno)
• CSS

I also have two years of professional experience with Go, but don't like it. Out of frustration about Go, I started playing with Rust. In general, I like to play around with different languages (like Clojure or C#), I even wrote my own little language) a while ago

Setup

Music

I listen to music on repeat when concentrating. It‘s weird that I‘m using Spotify for this purpose, but we have Spotify Duo so… yeah. The music changes a lot. My Spotify Wrapped in 2021 crowned me as one of the top people listing to Max Richter's Four Seasons. 2022 was more Architects (hat tip Bascht) and System of a Down (hat tip to my teenage angst). This might be because I did a lot of Go in the project (which is either because Go is close to the metal or driving me mad, you choose).

Conference Talks

I really like to give talks at conferences and user groups. I had the great honor to speak at conferences and user groups all over the world. Here are some of the conferences I've spoken at (but this list is heavily outdated):
