Infrastructure Planning
Played a primary role in capacity, budget, and project planning, including estimating effort, defining milestones, and setting priorities for both software development and hardware capacity.
Infrastructure as Code
Implemented infrastructure as code with Terraform, configuration management with Ansible, and developed custom services using Python, JavaScript, and Bash scripts for automation and management.
Virtualization & Containerization
Deployed OpenNebula (MultiMaster) Cluster for Virtualization Orchestration and Automation, along with Docker Swarm, K8S, CoreDNS, and Portainer for Container Orchestration and Management.
CI/CD & DevOps
Set up GitLab, GitLab-CI, GitLab-Runner, Harbor, and Ansible for Infrastructure as Code, Continuous Integration, Delivery, and Deployment, streamlining the development workflow.
Monitoring & Logging

Hybrid Cloud Architecture
Private Cloud
30% Public Cloud
Building A Robust Cloud Infrastructure
We deployed Shab's hybrid cloud architecture, implementing the complete physical and virtual infrastructure. This included setting up routers, firewalls, switches, and bare metal servers to create a robust foundation for their growing platform.
The resulting hybrid cloud architecture hosts 70% of Shab's infrastructure in their private cloud, with the remaining 30% distributed across two public cloud providers for redundancy and global reach.
- Multiple Kubernetes clusters across 4 datacenters (2 private, 2 public)
- Network design and implementation with redundant systems
- Hybrid cloud architecture with public cloud integration
- Cross-datacenter service discovery and load balancing
Technical Implementation
