Infrastructure & DevOps Services
I design and deploy scalable, modern infrastructure platforms—from bare metal to containers—bridging traditional systems with cloud-native technologies.
Core Services
Virtualization & Hypervisor Platforms
Enterprise-grade virtualization deployment and management:
- Proxmox VE: Cluster setup, high availability, Ceph integration, VM and container management
- KVM/QEMU: Libvirt-based virtualization for custom environments
- oVirt / OpenNebula: Enterprise virtualization platform deployment
Container Platforms
Container orchestration for development and production workloads:
- Kubernetes: Production-grade clusters on any infrastructure (on-premises, cloud, hybrid)
- Docker / Podman / Singularity: Container runtime setup and optimization
- Helm & Operators: Package management and automated operations
Workflow Orchestration & Job Scheduling
Automated workload execution across compute resources:
- Kubernetes-native: Argo Workflows
- Scientific Pipelines: Nextflow, Cromwell for bioinformatics and research workflows
- HPC Schedulers: Slurm, LSF configuration and management
- Resource Management: Kueue for job queuing and quota management
Infrastructure as Code
Automated, reproducible infrastructure provisioning:
- Terraform: Multi-cloud and on-premises provisioning (AWS, Azure, OCI, GCP, Proxmox)
- Ansible: Configuration management, automation, and orchestration
- Packer: Machine image building for consistent deployments
- GitOps: ArgoCD, Flux for declarative infrastructure management
Private Cloud Solutions
On-premises cloud infrastructure:
- OpenStack: Canonical Charmed OpenStack with MAAS + Juju
- Hybrid Cloud: Seamless workload movement between on-premises and public clouds
HPC Infrastructure
High-performance computing environment design and deployment:
- Cluster Architecture: Custom HPC cluster design for compute-intensive workloads
- Parallel Filesystems: Lustre, BeeGFS, GPFS deployment and tuning
- Bare Metal Provisioning: xCAT, Cobbler, MAAS for large-scale deployments
- Performance Optimization: Kernel tuning, network optimization
CI/CD & Automation
Streamlined delivery pipelines for infrastructure and applications:
- Pipeline Platforms: GitHub Actions, GitLab CI, Bitbucket Pipelines
- Container Registries: Harbor, GitHub Packages, Artifact management
- Image Building: Dockerfiles, multi-stage builds, optimization
- Release Management: Helm charts, GitOps workflows
Monitoring & Observability
Comprehensive monitoring solutions for infrastructure and applications:
- Metrics & Alerting: Prometheus, Alertmanager, custom exporters
- Visualization: Grafana dashboards, custom panels, alerting rules
- Log Aggregation: ELK Stack (Elasticsearch, Logstash, Kibana), Loki
- Custom Dashboards: Infrastructure and application-specific monitoring
ML/AI Infrastructure
Machine learning and AI platform deployment for training and inference:
- Kubeflow: End-to-end ML workflows on Kubernetes (training, serving, pipelines)
- MLflow: ML lifecycle management, experiment tracking, model registry
- KServe: Model serving and inference at scale
- Training Infrastructure: GPU/TPU cluster setup, distributed training
- Model Management: Versioning, registry, and deployment automation
