01. About Me

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.
