Cloud Architect & DevOps Consultant
Milad Seyfi
Cloud architecture for infrastructure that has to work.
Cloud engineer and DevOps consultant with hands-on experience designing, operating, and modernizing OpenStack, Ceph, and Kubernetes platforms. Work spans multi-datacenter infrastructure, platform automation, observability, service ownership, technical documentation, and mentoring.
Designing and modernizing OpenStack, Ceph, and Kubernetes with a focus on automation, reliability, and day-two operations.
- OpenStack scale
- 100+
- Ceph storage
- 50+ TB
- Deployment turnaround
- 60%+
About
Engineering depth, moving toward architecture.
My work connects infrastructure design to implementation, day-two operations, and the teams responsible for the platform.
I approach reliability, repeatability, operational ownership, and clear technical documentation as architecture concerns—not follow-up tasks.
- 01Make constraints explicit
- 02Design for day-two operations
- 03Automate repeatable work
