Christopher G.
Senior Network & Security Escalation Specialist /Infrastructure Eng/L3
I fix infrastructure before it becomes a fire, and when it's already on fire, I'm the one you call. I built and ran my own MSP for over a decade before moving into senior escalation and infrastructure leadership roles. I know what "get it done, don't just report on it" actually means, because I've sat in your seat. What I bring: - L3 escalation ownership on cloud, networking, and authentication incidents — 95% SLA resolution rate at Arlo Technologies, plus a 20% cut in MTTR by rebuilding the RCA process around structured log correlation in Splunk. - Network architecture end-to-end: OPNsense firewalls, VLAN segmentation, dual-WAN failover, Synology NAS — designed and deployed from scratch, not just maintained on top of someone else's build. - Security and compliance: patch management and hardening that cut exploitable vulnerabilities by 30% across 150+ client environments, plus current work leading ISO 27001 gap-closure and evaluating SOC 2 Type II, TISAX, NIS2, and BSI C5 feasibility. - Tooling fluency: ConnectWise, Zendesk, Freshdesk, ServiceNow, Jira, Salesforce, Tactical RMM, Prometheus, Zabbix, Grafana, Datadog, PowerShell. Why freelance instead of another full-time seat: I'd rather solve the problem directly than sit through the meetings about the meeting. You get direct senior-level attention, not a ticket triaged through three tiers before it reaches someone who actually knows what's wrong. Based in the Philippines, comfortable across US, UK, and APAC hours. Night shift isn't a hardship for me — it's a preference. If you need someone who can own a migration, own an escalation, or own a compliance push without hand-holding, that's what I've built my career on. Let's talk about what's actually broken.
