What types of infrastructure do you deploy? +
Proxmox, VMware, Hyper-V, MS AD, RDS, OPNsense, WireGuard VPN, Asterisk PBX, self-hosted AI stacks (Ollama, Dify, Weaviate), monitoring (Prometheus, Grafana, Zabbix), and self-hosted services (Vaultwarden, GLPI, Gitea). Full list in the packages section.
Do you work remotely? +
Yes, 100% remote. I'm based in Split, Croatia and work with clients worldwide. All deployments are done via SSH, VPN, or remote management tools.
How long does a typical project take? +
Starter packages — 1-2 weeks. Pro packages — 2-4 weeks. Full Stack + AI — 4-8 weeks. Timeline is agreed and fixed before we start. No surprises.
Is my data safe with self-hosted solutions? +
That's exactly the point. Everything runs on your server. No third-party APIs, no cloud lock-in, no data leaving your infrastructure. You own the data, the models, and the system.
Do you provide ongoing support after the project? +
Yes — monthly retainer available for every service. Includes updates, monitoring, alert triage, and SLA-backed response. Details are in each package section above.
What server do I need for AI deployment? +
Minimum for Mistral 7B: 16GB RAM, 4-core CPU, 50GB SSD. Recommended for Qwen3-32B: 64GB RAM, NVIDIA GPU with 8GB+ VRAM. I can advise on hardware selection during the discovery call.
