ABOUT
Infrastructure experience. Cloud security direction.
I’m Bruno Arruda, an infrastructure and security professional based in Ireland, building on years of experience in networks, systems, and information security to focus on AWS cloud security.
Built from infrastructure up
My career in technology was built from the infrastructure layer up. I started working with networks and systems and progressively moved deeper into infrastructure and information security, working across enterprise environments where reliability, availability, and security were part of everyday operations.
Over the years, my work has included network security, Check Point firewalls, vulnerability management, Windows and Linux environments, virtualization, backup infrastructure, ISO 27001 security controls, and hybrid environments spanning on-premises infrastructure and AWS.
Later, my work expanded into modern infrastructure, including Docker, Kubernetes, Rancher, CI/CD, and highly available production environments. That experience changed the way I look at security: not as something added after infrastructure is built, but as part of how systems should be designed and operated.
Today, I’m bringing that background into AWS cloud security. My focus is on developing deeper cloud architecture and security expertise through hands-on labs, real implementations, and continuous study - then documenting what I learn here.
How I approach the work
A practical approach to developing cloud security expertise: understand the fundamentals, build the solution, and document what matters.
Learn deeply
Understand the architecture, services, security principles, and trade-offs behind a solution before implementing it.
Build practically
Turn concepts into hands-on AWS environments, security configurations, architectures, and real-world technical scenarios.
Document clearly
Capture architecture decisions, implementation steps, findings, and lessons learned so the work can be understood, reviewed, and improved.
Professional background
Experience built across infrastructure, network security, modern platforms, and cloud environments.
