Germany · infrastructure & software

I build apps and run the infrastructure they live on.

I'm Maurice, or Doxylamin most places online. Infrastructure is my day job: virtualisation, networking, mail, DNS, monitoring, single sign-on. The rest of the time I build for iOS, Android and the web, usually because I wanted an app that didn't exist yet.

01 What I do

Ship apps

iOS, Android and web, from the first sketch through to the support inbox after release. I pick the stack to suit the problem rather than the other way round, so it's rarely the same twice. All of them have real users.

Run the platform

Everything I build runs on hardware I look after myself: virtualisation, mail, DNS with DNSSEC, single sign-on, metrics and alerting, and backups I restore-test on a schedule. It's meant to be boring, and mostly it is.

Keep a community running

I've helped run Enter The Void since 2016. It's a German gaming and tech community with its own game servers, Discord tooling, LAN parties and festival trips. A fair few of my projects started there.

02 Projects

Four things I actively build and maintain.

CrewMate

Early access

Festival crew coordination in one place: rides, camping spots, timetables, shared expenses, meetup pins and emergency alerts. Built after one too many weekends spent reconstructing who owes whom from a 400-message group chat. Free, and available in five languages.

Tellyfin

Open source

A native Android TV app for watching live TV from your own Jellyfin server: full-screen HLS, D-pad channel zapping with a preview countdown, a proper EPG guide and favourites. Think waipu.tv, except the server is yours. Kotlin, Jetpack Compose and Media3.

AVION2

Open source

A damage meter and fight analyzer for AION2. It reads the game's network traffic on your PC, shows each player's damage live in an overlay and saves every fight for a replay and a skill-by-skill breakdown. It also has a compass that finds hidden cubes. Windows, written in C#.

Enter The Void

Since 2016

A German gaming and tech community: free game servers on our own hardware, modding and technical help, events, and a Discord where someone is always around. I look after the infrastructure and the self-service tooling behind it.

03 The stack

Not a skills matrix, just what's in use right now. The app side changes with every project. The platform underneath it tends to stay put.

Verifying it's really me

People do impersonate me now and then. My TeamSpeak identity fingerprint is UfYAU5UD0MLq/WrF2o+xhnYL+ac=, so compare it before you trust a "Doxylamin" you meet there. On Discord, check the account ID 140541588915879936 rather than the display name, which anyone can copy. Full contact details, including donation addresses, are in contact.txt.
