Work
A selection of infrastructure, security, and systems engagements — the kind of work Nexbee is built to take on — architectural decisions, hands-on implementation, and long-term ownership.
Security & Access
Zero Trust Access & Identity Management
Replaced a legacy VPN with Cloudflare Zero Trust, routing all remote access through identity-aware tunnels authenticated via Azure AD SSO. Eliminated broad network access in favor of per-application, least-privilege control.
- Decommissioned legacy VPN and removed the attack surface it represented
- Browser-based access to internal tools with MFA and conditional access enforced
- Reduced support overhead from VPN client configuration and failures

Centralized Identity & Device Management
Deployed Active Directory across approximately 100 endpoints at three sites plus remote staff — replacing local accounts and manual processes with governed identity, group policy enforcement, and auditable lifecycle management.
- Unified visibility and control over users and devices across all locations
- Streamlined onboarding and offboarding with defined provisioning workflows
- Established foundation for Azure AD and SSO expansion

Infrastructure & Reliability
High-Availability Virtualization Platform
Architected a five-node Proxmox cluster with integrated Ceph storage. Logical network segmentation, bonded interfaces, and HA policies provide fault-tolerant VM hosting without manual intervention during hardware failures.
- Node failures handled automatically without service disruption
- Centralized VM and storage management with 3x replication across nodes
- Shared storage pools accelerated new service deployment

Automated Infrastructure Provisioning
Built a modular Terraform and Ansible pipeline for VM provisioning and configuration on Proxmox. Reusable modules, cloud-init templates, and idempotent playbooks replaced manual setup with repeatable, source-controlled deployments.
- VM deployment time reduced from hours to minutes
- Configuration drift eliminated across dev, staging, and production
- Infrastructure changes tracked, reviewed, and reproducible

Centralized Configuration Backup Architecture
Deployed TrueNAS with ZFS RAIDZ2 as a fault-tolerant backup target for configuration data across the full infrastructure — network devices, servers, and services. Automated rsync pull jobs run on schedule with full logging.
- All critical configuration data centralized in one fault-tolerant location
- Reduced recovery time with fast, documented restoration procedures
- Verifiable backup history with timestamped sync logs

Operations & Visibility
Building a First Internal IT Function
Designed and stood up an organization's first formal IT department. Assessed infrastructure gaps, deployed a ticketing system, wrote SOPs for core operations, and developed internal staff into dedicated IT roles.
- Reactive, fragmented operations formalized into documented, scalable processes
- Onboarding, offboarding, asset tracking, and incident handling standardized
- Internal knowledge base reduced support burden and improved consistency

Operational Data Visibility Platform
Aggregated CRM, telephony, and production data into a centralized Grafana dashboarding system. Replaced manual spreadsheet reporting with real-time, automated visibility into operations across departments.
- Real-time KPI visibility across executive, operations, and support teams
- Manual reporting replaced with automated, real-time metric generation
- SLA alerting and trend analytics enabled proactive decision-making

Call Center Phone System
Replaced a failing legacy PBX with a production FreePBX deployment customized for the organization's call flows. Custom IVR, queue logic, redundant SIP trunks, and DID-based tracking gave operations and marketing a reliable foundation.
- Reliable call routing and queue performance replacing frequent system failures
- Marketing campaign attribution through dedicated DID tracking
- Mobile softphone integration for agent mobility and continuity
