Freelance · System Integration
Infrastructure built to run quietly in the background.
Specializing in |
I design and operate networks on MikroTik, Fortinet, Cisco, and Ubiquiti, and build the server infrastructure behind them — from a single Proxmox box to a multi-node cluster with proper monitoring and automation.
Network Design
Corporate network design built on Cisco, Fortinet, MikroTik, and Ubiquiti — including Active Directory and SSO setup.
Server Design
Server rack design, performance estimation, thermal profiling, hyper-converged infrastructure, and SAN-based hypervisor design.
IoT System Design
Open-source IoT systems, engineered to meet each client's specification.
Electronics Design
Custom PCB design with microcontrollers, multi-board systems, and full solution engineering.
Selected work
A selection of network integration and infrastructure automation projects, delivered end to end.
Multi-Node Proxmox Infrastructure
Architected and operate a 6-node bare-metal Proxmox cluster, hand-routed on MikroTik CRS/CHR hardware, segmented into VLANs, tunneled with WireGuard, and fronted by Cloudflare Tunnel — zero open inbound ports, zero-trust by default.
