Activation Specialist · Mekari Qontak · Tangerang, Indonesia

Systems that stay up.
Clients that succeed.

Infrastructure Engineer who builds homelabs, automates pipelines, and deploys production systems — from bare metal to zero-trust VPN. Published researcher in computer vision for agriculture and medical imaging.

I run a production-grade homelab on Proxmox VE — 15+ self-hosted services, VLAN-segmented networking, Cloudflare Tunnel, and Tailscale VPN for remote access. Every deployment is scripted, version-controlled, and reproducible.

I've published research in precision agriculture (RetinaNet for oil palm ripeness detection) and medical imaging (ResNet50 for brain tumor classification). I also automate infrastructure pipelines with PowerShell and Bash — backups, deployments, and alerting.
