Computer Systems & Network Engineer
📍 Melbourne, Australia
I'm a passionate Computer Systems & Network Engineer with 5+ years of hands-on experience spanning enterprise IT support, network infrastructure, and virtualization. My journey started in Mauritius supporting offshore maritime IT operations, and has evolved into architecting full-stack virtualized environments in Melbourne.
Currently designing high-performance infrastructure using Proxmox VE, OPNsense, and open-source security tools at Wabify, while also contributing to IT operations at Faster Financial (CashFaster). I specialize in bridging the gap between traditional IT operations and modern cloud-native infrastructure with a strong focus on cybersecurity.
Pursuing a Bachelor's degree in Information Technology at Melbourne Polytechnic while actively building production-grade infrastructure — because the best learning happens when theory meets real-world challenges.
Core competencies honed across 5+ years of real-world infrastructure challenges.
Designing and deploying production-grade virtualized environments with Proxmox VE, managing VM lifecycles, storage, and high-availability configurations.
Implementing multi-layered security with firewalls, VPNs, network segmentation, and zero-trust principles. Fortinet, Palo Alto, and OPNsense expertise.
Building resilient networks with VLANs, DNS, DHCP, NAT, and advanced routing. CompTIA Network+ certified with hands-on enterprise experience.
Managing Linux and Windows Server environments, Active Directory, backup strategies with Veeam, and enterprise application support across diverse industries.
Migrating workloads between cloud providers and on-premise infrastructure. AWS to self-hosted transitions with zero downtime and cost optimization.
Diagnosing complex infrastructure issues across network, systems, and application layers. From offshore maritime environments to fintech platforms.
Interactive visualization of a production infrastructure I've designed. Click on nodes to explore details.
Transforming a basic hosted application into enterprise-grade financial infrastructure.
Core financial systems completely isolated from public internet. All access mediated through hardened gateway services.
HAProxy distributes traffic across application servers with health checks, SSL termination, and automatic failover.
100GB+ MySQL databases migrated with zero data loss. ZFS snapshots and automated backup pipelines for disaster recovery.
WireGuard tunnels for all administrative access. No SSH or management ports exposed to the internet.
