01 — Summary
A practitioner of resilient, secure infrastructure.
Global Remote Ready
Fully aligned with US time zones, highly experienced in asynchronous communication, and operating from a secure home office with 100% redundant internet and power backups.
"I build systems that quietly do their job — secure, monitored, and predictable."
I'm a Systems Engineer with over seven years of experience across MSP and enterprise IT infrastructure. My work spans Microsoft 365 and Azure administration, Active Directory and PowerShell automation, and networking — including firewalls and VLAN routing.
I've worked extensively with PSA and RMM tooling inside MSP environments, managing IT infrastructure and client networks across diverse industries while ensuring strict SLA compliance.
A core part of my craft is designing backup and disaster recovery strategies that protect business continuity end-to-end.
"Hi, I'm Sam. Let's build something resilient."
