During office hours I'm building software and services in the context of large-scale storage systems at Karlsruhe Institute of Technology. Some of that work is open-source:

• WebDAV server software based on Apache HTTPD for data access and transfer. Most projects are open-sourced at Helmholtz's GitLab.
• Tools supporting system operations:
  • lsdf-checksum computes file content checksums to verify integrity.

At other times, I'm playing with technology and tend to over-engineer software to marginally improve my life 😬.

Quite a few topics in the technology space I've been following for some time:

• Data Storage and Processing (Databases, Processing and Analysis Engines, Workflow Systems, Programming Models and Paradigms, ...)
• Deployment and Operations of Software Application (Orchestration Systems, GitOps, Monitoring, ...)
• Distributed Systems (Network Protocols, Distributed System Architecture, Consensus Protocols, CRDTs, CAP, Caching, ...)
• Building Engineering Organisations (Communication, Processes, Culture & Peopleware, Planning, ...)
