Hello, I'm Rachman
I don’t chase tools or trends. I focus on building systems that survive real-world problems: power outages, unstable networks, and human error.
Stability is not accidental — it’s a design decision.
Networking & VPN
ZeroTier, MikroTik, Zero Trust, DNS management
Virtualization & Servers
XCP-NG, Ubuntu Server, VM management, hot-add disk
DevOps & Deployment
Docker, Traefik, CI/CD pipelines, monitoring & logging
Problem Solving
Build from zero, system stabilization, disaster recovery, fault-tolerance
End-to-end Stable Infrastructure
Built XCP-NG + Ubuntu + Docker + Traefik infrastructure integrated with ZeroTier & Zero Trust VPN, achieving 24/7 uptime and automated recovery.
Automation & Monitoring
Implemented deployment & monitoring pipelines, reducing errors by ~70% and ensuring rapid recovery during failures.
Cross-team Enablement
Designed systems that allow frontend teams to deploy independently without affecting backend stability or uptime.
