Sean Grossnicklaus
I architect, harden, and automate enterprise infrastructure across 10,000+ endpoints. With over a decade of hands-on systems engineering, I bridge custom kernel-level telemetry (ETW), zero-touch deployment pipelines, and ConnectWise SME architecture to eliminate operational friction, guarantee 99.99% uptime, and scale mission-critical environments.

Kernel-Level ETW Telemetry & Ringfenced SecOps
I engineered custom endpoint detection routines using Event Tracing for Windows (ETW) to inspect kernel events in real time. By coupling low-overhead telemetry probes with SentinelOne EDR and ThreatLocker application ringfencing, zero-day behaviors and unauthorized binary executions are isolated before laterally traversing the domain.
Key platforms designed and implemented with full-stack resiliency and zero vendor lock-in.
CompanyLister.com
I architected CompanyLister from scratch as a unified multi-tenant platform combining automated bare-metal Linux server provisioning, DNS synchronization, AI site generation, and real-time remote desktop streaming with zero third-party agent dependencies.
K12OnlineSchooling.com
I engineered a resilient, containerized educational ecosystem built on a Free Education for All philosophy. Features automated grading pipelines, isolated parent, student, and teacher portals, and containerized staging environments handling rigorous multi-tenant workloads.
MMORPG3D.com
I engineered a zero-download 3D multiplayer browser engine featuring real-time client-server synchronization over low-latency WebSockets, procedural 3D terrain rendering, character customization pipelines, and client-side interpolation.
Proven enterprise track record leading technical operations, security automation, and infrastructure engineering.
Coastal Plains Meat Company
I direct the engineering, deployment, and operational scaling of plant-wide enterprise IT infrastructure, industrial automation and SCADA telemetry, and B2B workflow integrations across manufacturing operations.
- Modernized supply chain and processing telemetry through custom Python and PowerShell pipelines, significantly reducing manual administrative overhead and ensuring 100% compliance with strict USDA and regulatory standards.
- Championed high-availability hybrid networks, hardening perimeter defenses, optimizing server virtualization, and implementing resilient data recovery protocols to guarantee zero unplanned facility downtime.
Schultz Technology
I spearheaded centralized IT automation, telemetry monitoring, and patch orchestration across 10,000+ active enterprise endpoints, maintaining 99.99% infrastructure uptime and compliance.
- Architected proprietary endpoint detection and response tools utilizing Event Tracing for Windows (ETW) for real-time kernel-level visibility, integrating seamlessly with SentinelOne and ThreatLocker for automated threat neutralization.
- Designed zero-touch deployment pipelines and automated patching frameworks, eliminating over 85% of repetitive manual technician remediation efforts across diverse managed client environments.
- Developed automated PowerShell and Python monitoring routines to conduct continuous vulnerability auditing, endpoint health validation, and automated self-healing service restoration.
CBM Technology
I served as primary Subject Matter Expert (SME) managing ConnectWise Manage and Automate infrastructure for 7,000+ endpoints, engineering custom automation scripts, API integrations, and unified alerting logic.
- Led end-to-end design and execution of complex client infrastructure migrations from aging on-premises hardware to Microsoft Azure, private cloud, and VMware ESXi / Hyper-V high-availability clusters.
- Orchestrated enterprise backup and disaster recovery protocols utilizing Veeam Backup & Replication, Datto BCDR, and Acronis Cyber Protect, consistently achieving strict RPO and RTO compliance.
- Advised executive clients on network security modernization (Fortinet FortiGate, Cisco Meraki, SonicWall), zero-trust architecture, and long-term technology roadmaps.
US Army National Guard
In the US Army National Guard, I engineered and maintained tactical military IP networks, high-availability routers, switches, and COMSEC encryption hardware under high-stakes, austere operational field conditions. Concurrently, as a 92Y Logistical Specialist, I maintained 100% asset accountability and database compliance for millions of dollars in mission-critical defense inventory.
Extensive domain mastery across systems, security automation, cloud virtualization, and enterprise ecosystems.
