Audit
Infrastructure & Risk Assessment
Remote deep-dive into your networks, servers, HA stack, and security posture. Clear report with a prioritized list of risks and recommended remediation steps.
Carlos Rafael Pasqualini
Infrastructure & Network Architect
Available for remote consulting
Designing and stabilizing critical infrastructure.
I help organizations audit, redesign, and troubleshoot networks, servers, and high-availability systems so that infrastructure stops being a risk and becomes an asset.
Typical problems I solve
- Unstable or poorly segmented networks.
- Failing HA clusters and virtualization platforms.
- Security gaps and misconfigurations in critical services.
- Legacy infrastructure blocking new projects.
- Systems that work, but nobody really understands or documents.
Services
Focused on architecture, diagnosis, and risk reduction — not generic “IT support”.
Architecture
Network & Topology Redesign
VLAN segmentation, routing, firewalls, DMZs, and connectivity between environments. Designed to reduce blast radius, simplify operations, and support future growth.
Troubleshooting
Stabilization & Incident Recovery
Systematic root-cause analysis for recurring failures, performance issues, and outages in virtualized and physical environments.
Selected work
Examples of the kind of infrastructure I work with.
Network redesign
University campus segmentation & security
Redesigned campus-wide network with VLAN segmentation, DMZs, and controlled inter-VLAN routing for academic, administrative, and public services.
Result: fewer lateral-movement risks, clearer boundaries between environments, and a documented, repeatable design.
HA & virtualization
Cluster assessment and hardening
Audit of a Linux-based virtualization cluster hosting critical applications. Analysis of storage, failover behavior, and recovery procedures.
Result: hardening measures, clearer operating procedures, and a validated recovery plan aligned with business expectations.
How I work
Structured, remote-friendly engagement. No surprises.
Step 1
Intro & scoping
30-minute call to understand your current infrastructure, pain points, and constraints.
Step 2
Access & assessment
Read-only access, documentation review, and targeted interviews with your technical team.
Step 3
Report & next steps
You receive a concise report with findings, risks, and a prioritized action plan.
About
I am an infrastructure and network architect based in Argentina, working remotely with organizations that need stable, well-designed systems rather than quick fixes.
My background includes 20+ years designing and operating Linux-based infrastructure, campus and data-center networks, virtualization clusters, and services for universities, SaaS products, and industrial environments.
