Welcome to my Infrastructure & Cloud Engineering Portfolio — a collection of projects showcasing how I design, secure, and automate resilient IT environments.
With over 20 years of experience across mining, finance,telecoms and managed service environments, I specialize in:
- Hybrid Cloud & Virtualization (Azure, VMware, Hyper-V)
- Platform Modernization (Windows Server, HPE/Dell Compute, Veeam)
- Security & Network Optimization (FortiGate, SonicWall, IDS/IPS, VPN)
- Automation & Continuity (PowerShell, Terraform, ITIL-based DR)
Each project below highlights my hands-on work — from infrastructure rebuilds to DR automation and high-availability configurations.
Objective: Modernize and standardize infrastructure across multiple business units.
Highlights:
- Migrated legacy servers to Windows Server 2022 (Hyper-V + VMware hybrid)
- Upgraded compute and storage platforms (HPE 3PAR, Synology, EMC)
- Automated patching with SCCM & PowerShell
- Achieved 99.9% uptime and 20% cost savings
Objective: Ensure business continuity through real-time vSphere replication between two data centers.
Highlights:
- Configured replication with a 5-minute sync cycle
- Automated DR testing via PowerCLI
- Documented DR workflows with RTO/RPO metrics
- Zero data loss and recovery in under 45 minutes
Objective: Redesign network security infrastructure to enhance visibility, control, and VPN reliability.
Highlights:
- Deployed and tuned FortiGate IDS/IPS
- Optimized SSL VPN with MFA
- Deployed IPsec tunnels for site-to-site resilience
- 70% reduction in intrusion attempts and 80% fewer tickets
Objective: Deploy and manage Exchange Server 2019 DAG clusters for enterprise email reliability.
Highlights:
- Migrated Exchange 2010 → 2019 with zero data loss
- Configured 2-site DAG cluster with automatic failover
- Integrated hybrid Exchange Online model
- Maintained 99.8% uptime across 2,000+ users
Objective: Create a modern SharePoint Online portal to replace legacy on-premises file servers, ensuring governance, collaboration, and data integrity.
Highlights:
- Conducted full inventory and permissions mapping from on-prem file shares.
- Designed SharePoint site collections aligned to business units (Finance, HR, Operations, Projects).
- Applied Azure AD group-based access to maintain original security posture.
- Introduced metadata-based libraries and eliminated folder sprawl.
- Automated document approval and retention workflows using Power Automate.
