“Architecture is not the design of systems. Architecture is the design of understanding. It's how an organization perceives risk, anticipates constraints, builds consistency, and aligns technology with purpose.”
I'm a Senior IT Solutions Architect who started at the bottom of the stack and never really left it. Thirteen years ago I walked into Angola LNG as a Server Administrator, patching servers and chasing Exchange queues. Somewhere between the 3 a.m. troubleshooting and the compliance audits, I started seeing patterns instead of tickets — and by 2018, that shift had earned a new title: Architect.

Selected writing on architecture, data protection, and continuity. Published on LinkedIn.
Confusing Business Continuity with Disaster Recovery is a common — and costly — mistake. A solutions architect's view on why the two are different disciplines, and how getting that distinction right protects an organization when things go wrong.
Original: “Continuidade do Negócio vs. Recuperação de Desastres: a Visão do Arquitecto de Soluções”
Reflections on knowledge-sharing culture in IT — from Angola's oral tradition of sharing knowledge under the imbondeiro tree, to why that same openness disappears the moment we walk into an IT department, and what it costs us.
Original: “Partilhamos pouco. E isso custa-nos mais do que pensamos.”
Green IT is no longer a passing trend. Data centers consume up to 1% of global energy — a look at liquid cooling and other concrete strategies for building digital infrastructure that respects the planet.

Angola's digital growth has outpaced its data-protection practices. A look at the legal framework (Lei n.º 22/11, the 2020 Penal Code update) and what organizations still need to do about DLP, training, and international cooperation.

Section / 05 · The Ledger
IT Solutions Architect at Angola LNG — thirteen of my twenty-plus years in IT, after six years in banking at BFA. I design and review the systems a plant runs on around the clock, which in practice means IT/OT integration, identity, and making sure a server change doesn't stop a shift. Azure architecture and security (AZ-303/305/500), ISO 27001, and the Enterprise Architecture Review Process that now gates significant change here. I wrote that one.
Open-source PowerShell that builds Windows 11 reference images by servicing the WIM offline with DISM, rather than running debloat scripts on every machine after Windows installs. The removal happens once, in the image, before any hardware exists, so first boot is already the final state and there is nothing left for a user to interrupt. Eleven sequential scripts, each dry-run by default, plus a reference-VM stage with THIN and THICK software profiles.
A Portuguese-language platform for teaching children to touch-type.
An information-security blog written from Angola, for people working in it. Mostly data protection, and the gap between security advice written elsewhere and what actually holds up here.
A GitHub collection of PowerShell scripts for everyday system administration: reboot reminders, Teams cache clearing, duplicate and empty-folder finders. Each one written because the manual version had been done one time too many.
An Angolan community for security and technology practitioners, running since 2011.
