Osvaldo de Sousa

Hi, I’m Osvaldo

I’m a Mozambican IT professional with over 20 years of experience, currently working as a Cybersecurity Analyst at Hidroeléctrica de Cahora Bassa (HCB) — one of Africa’s largest hydroelectric power plants. My career has taken me through systems analysis, networking, service desk management, and now security operations in critical infrastructure.

I’m based between Songo, Tete and Maputo, Mozambique, and I write here about infosec, networking, homelabs, and whatever I happen to be learning or breaking at any given moment.

Who I Am Outside Work

Photography I shoot with an Olympus OM-D E-M10 Mark II and a 12-40mm f/2.8 Pro lens. I’m drawn to portraits and available light situations. Photography and security share more than people think — both reward patience and attention to detail.

Hi-Fi Audio & Acoustics I run a serious dedicated audio system — Naim amplification, Dynaudio Heritage Specials, REL subs, and a Holo Audio R2R DAC fed by a Roon ROCK server. All on its own isolated VLAN. Full details on the Hi-Fi page.

Home Lab My home network is a project that never ends. MikroTik, UniFi, Raspberry Pi, Docker. Currently planning a Proxmox node for security research and testing.

Football Manchester United supporter. Results not always matching expectations, but loyalty is unconditional.

Family Proud father to Nowa.
