Journey

This is where I document my engineering journey: projects I build, open-source contributions, and technologies I explore.

Open Source

Projects I have contributed to.

Systems, platforms, and products I have designed, built, and operated professionally.

Cloud Infrastructure Platform
- Building and operating cloud infrastructure based on OpenStack, Ceph, monitoring, and automation.
Cloud Image Platform
- A CI/CD-based platform for building, testing, and publishing cloud images using Image-as-Code principles.
Shared File Storage Service
- A scalable NFS-based shared storage solution for cloud environments.
Multi-AZ Backup Platform
- A backup and disaster recovery solution for OpenStack environments with migration workflows between Ceph and S3-compatible object storage.
eBPF-based Network Billing System
- A scalable network traffic accounting system using eBPF for kernel-level data collection.

Ceph Platform Evolution
- Migration of large-scale Ceph deployments from ceph-ansible to cephadm, improving deployment, operations, and maintainability.

Technologies and concepts I am currently exploring to deepen my understanding of systems engineering.
