- Vulnerability assessments of SOUP components for international regulatory compliance
- Quality Management System (QMS) documentation for regulated industries
CROSS-INDUSTRY EXPERIENCE
I've delivered infrastructure solutions across three distinct sectors, giving me perspective on different operational requirements:
Hospitality — Multi-site network architecture, segregated guest WiFi, vendor access management, high-availability systems for customer-facing services
Retail — Large-scale distributed networks supporting 460+ store estates, POS system integration, centralised management across geographic locations
Medical Devices — Clinical Interface systems, FDA/TGA/EU MDR regulatory compliance, secure device provisioning, QMS-aligned documentation
RECENT PROJECT EXAMPLES
Cloud Transformation: Architected complete on-premises to cloud migration including Active Directory to Entra ID, enterprise-wide zero-touch device provisioning via Autopilot, file server migration to SharePoint and Azure Blob Storage, and successful domain controller decommissioning — all delivered with zero business disruption.
Network Architecture: Designed dual-edge network infrastructure with segregated public connections using RG701H RADIUS Gateway for vendor and guest networks, and WatchGuard HA firewall cluster for admin network. Implemented VLAN segmentation within each zone with secure inter-network communication capabilities.
M365 Migration: Executed zero-downtime tenant-to-tenant migration using Microsoft Purview eDiscovery for PST, SharePoint, and OneDrive content migration. Delivered complete data integrity with minimal user impact.
Unified Communications: Delivered PBX to Microsoft Teams Phone System migration with multi-level auto attendants, call queues with agent assignment and overflow handling, and DID number assignment — modernising communications infrastructure with zero service interruption.
AI-AUGMENTED OPERATIONS
I also build production tools at the intersection of infrastructure and AI:
- MCOL — open-source multi-LLM orchestration CLI
- XpertNepal — production full-stack civic-tech platform shipped end-to-end with Claude Code
This means automation that goes beyond traditional PowerShell — AI-assisted documentation, smart runbook generation, and integration workflows.
