A formal record of real engineering cases — documented as they happen.

5G Core Cloud Native Kubernetes eBPF Networking ML

About this repository

Every entry is a real case — something that was built, broken, debugged, designed or observed while working across 5G core, cloud-native systems, networking and applied ML environments. Each case is documented formally with enough context and detail to be useful beyond the moment it happened.

The goal is to build a reference that survives memory and that others working in the same space might find useful.
