Software development

C/C++ (♥), Python, PHP, HTML, CSS, JS, QBASIC, Java or Kotlin. I speak them all! My favourite rendering APIs? Vulkan, OpenGL and GLSL. Librarys? Here my most frequently used ones: Python Flask, Vulkan SDK, libCurl, GLUT, GLAD, SDL2 and GTK+.

Development operations

DevOps? Of course! Gitlab CI, Docker and Kubernetes: Starting with just some code formatting checks up to tested and scaled, auto-deployed and prodution-ready apps - even this site is part of my CI pipeline!

Software engineering

I love to design systems: Starting by just the internal class diagrams of a server instance up to the whole backend API and frontend representation.

Systems administration

Linux is my world - therefore my love to the LAMP stack! I also enjoy working with a lot of other server-related software: Virtualisation (KVM, Docker), storage (ZFS), serving (miniDLNA, Nextcloud) or management (Netdata) are only some of my expertises!

Webdesign

You need a website or want to modify an existing one? Wordpress, Joomla and now Hugo - I worked with all of them. Or maybe you just want to redesign some static content…

UI/UX

You need an intuitive and unique interface design for your next project? Whether you work with a C++ rendering pipeline or just need some JS with CSS - I’m here to help you!

Incoming maintenance! Hey, little heads up regarding a server maintenance - the expected downtimes of the server and all of my services are: 2021.05.16 20:00 - 2021.05.16 23:00 That’s nice, but… …what will be changed? An SSD failed this morning and must be replaced soon - current operation is not (yet) affected A new power cable for the HDDs will be installed Please note, that after that timeframe some services may not work properly and therefore do not hesitate to contact me if any problem persists too long (not everything is monitored from my backend).

Maintenance RSS Feed

on April 27, 2021 11:09

What’s that?! Okay, in the recent years I’ve become a service provider to more and more people (which is fine by me), but when I need to do maintenance to my server I now have to contact all of them. Individually. Using their preferred way of communication. Me, contacting all of you - visual representation only, not actual footage. As you may imagine, this is sort of a pain in the b*tt - especially when I need to move the maintenance window or may want to report about outages… So here is my solution: As I already have my website on which I publish maintenance notes and also already render the needed RSS feeds - why not use these?
