Real results.
Full Network Migration to UniFi
Planned and executed a complete network infrastructure migration to the Ubiquiti UniFi ecosystem. Replaced legacy hardware, redesigned VLANs, and delivered zero-downtime cutover for production environments.
Microsoft 365 Migration
Executed full organization migration to Microsoft 365 — mailboxes, SharePoint, Teams, and identity management. Handled data migration, DNS cutover, and user onboarding with minimal disruption.
RMM Agent Automation
Deployed remote monitoring and management agents across client fleets. Automated patch management, alerting, and system health reporting — reducing manual intervention by hours per week.
Firewall Hardening & VPN Rollout
Implemented enterprise-grade firewall policies across MikroTik and pfSense deployments. Rolled out WireGuard and OpenVPN tunnels for secure site-to-site and remote access.
Server Virtualization & Backup Systems
Migrated physical servers to Proxmox and VMware clusters. Built automated backup pipelines and disaster recovery procedures — tested and documented for fast failover.
IP Camera & Access Control Deployments
Designed and deployed IP surveillance systems with NVR integration. Configured remote access, secure storage, and network segmentation for camera traffic across multiple client sites.
The stack behind the systems.
Not just another
IT guy.
Real-World Experience
Years of hands-on production work, not classroom theory. Every solution tested under real conditions with real clients.
Fast Under Pressure
Systems go down. Networks fail. I fix them fast. Built for high-pressure environments where downtime costs money.
Clean, Scalable Solutions
No band-aid fixes. Every implementation is structured, documented, and designed to grow with your business.
Security-First Mindset
Security isn't an afterthought. It's baked into every network design, server config, and access policy from day one.
Long-Term Reliability
I don't build systems that need constant babysitting. The goal is infrastructure you can trust — today, next quarter, and years from now.
Currently available for freelance projects, long-term contracts, and full-time positions. Let's build something reliable together.
