Principal Systems Architect · Las Vegas, NV
I'm Anthony Klein — an independent infrastructure architect with two decades of experience building the systems that enterprises and high-growth startups depend on. Cloud architecture, SRE, IAM, and security automation — delivered with the calm of someone who has seen every failure mode.
What I Do
Multi-cloud strategies built for real-world constraints — cost efficiency, zero-downtime migrations, and infrastructure that your team can actually operate. AWS, Azure, and beyond.
Stop firefighting. I implement SLIs/SLOs, build Grafana/Prometheus dashboards, and establish incident response protocols so your team knows what broke, why, and how to prevent it next time.
Identity and access done right — Okta, SSO, LDAP, Zero Trust architecture, and automated provisioning. Passed SOX audits with zero findings. Security that doesn't block your team.
Terraform, Ansible, Docker. Your infrastructure becomes version-controlled, reproducible, and testable — not tribal knowledge living in someone's head or a runbook nobody updates.
From zero-day device enrollment to endpoint hardening and fleet policy enforcement — I've built and managed the full corporate IT stack at high-growth startups. MDM, SaaS stack consolidation, secure onboarding at scale. The operational foundation that lets engineering teams focus on shipping.
Not every organization needs a full-time senior infrastructure hire. I work with smaller teams and early-stage companies as an embedded technical partner — available for retainer engagements, architectural guidance, or simply having someone experienced in your corner when the hard calls come up.
Experience
Built the Sunnyvale office network and full cloud infrastructure from scratch for a Series A hardware startup. Automated onboarding for 50+ endpoints, validated product benchmarks across Linux distributions, and set up Azure AD, SSO, and RBAC from day one — in time for launch.
Managed corporate AWS infrastructure at scale — reduced cloud spend by 20% without touching uptime. Led IAM initiatives across Okta and OneLogin that passed SOX audits with zero findings. Built Python and Terraform automation that freed engineering teams from repetitive toil.
Migrated critical JIRA and Confluence workloads to AWS. Managed GitHub Enterprise for 2,000+ developers, applying Ansible automation to harden security without causing access disruptions.
Nearly 8 years embedded in Apple's IS&T organization — part of a cross-functional team supporting enterprise infrastructure at one of the world's most demanding IT environments. Administered Oracle LDAP directory services and Oracle Solaris hosts at scale, and led high-availability webmail deployments with deep Oracle LDAP integration. The kind of work where uptime isn't a goal — it's a given.
Full career history — including earlier enterprise tenure — is on LinkedIn.
