Hi! I'm Markus, a versatile freelance software engineer with a focus on – but not at all limited to – game back-end development.
Within that role, I'm a seasoned amateur in many fields, and always aiming to strike a good balance between making things work quickly, and keeping them maintainable for the long haul. Taking responsibility in all phases of the software lifecycle, including operations, has always felt natural to me (way before DevOps became a word).
If you have a project that I might be able to help you with, please get in touch! I'm happy to negotiate rates based on project scope and budget, and generally more excited about doing interesting work than making a fortune.
I am based in Munich, Germany, and experienced with working remotely.
Here's a selection of things I have been working on in the past two or three years. Feel free to have a look at my traditional CV for more details about these, and about earlier work.
Designed and implemented the REST API backing a mobile app and webapp, providing realtime chat, appointment scheduling functionality and various types of content material to clients and their coaches.
Also helped out refactoring and extending the React/React Native+Redux based clients.
An interim solo project: Built a simple puzzle game using the libGDX framework, with a deliberately narrow scope, in order to improve client-side skills and exercise an entire app development cycle within a limited amount of time (4 months from idea/prototype to release).
Designed and implemented the horizontally scalable back-end service/REST API that managed player data and provided core game functionality to the Android and iOS clients.
As part of a nimble startup team, I also took care of a significant portion of the infrastructure setup and maintenance work (CI/CD environments, operations monitoring etc), and contributed to game design extensions and new features beyond the initial project scope.
Eleven Giants is a community-driven open source project aiming to bring the previously shut down commercial MMO game Glitch back to life.
As time permits, I am contributing to these efforts as part of a globally distributed team of volunteers. This primarily means extending the Node-based game server that provides the persistent realtime game environment, and provisioning and maintaining various parts of the infrastructure.
