Technical Documentation

Operational documentation for the live platform behind shellr.net.

This site documents the live platform behind shellr.net from an operations perspective: service boundaries, routing, deployment, monitoring, logging, backup, and recovery on a single Hetzner VM. The goal is not tool hype. The goal is a system that stays understandable when it changes, fails, or has to be handed over.

Platform Summary

Hostnames and service boundaries

Why this matters Each public hostname maps to one service boundary. That separation makes the platform easier to deploy, monitor, secure, and explain under review.
Hostname Purpose Target
shellr.net Personal landing page and frontdoor Portfolio app container
dma.shellr.net DMA application DMA PHP container
grafana.shellr.net Metrics and logs UI Grafana behind Nginx auth
status.shellr.net Uptime surface Uptime Kuma

Start here

Review the architecture first, then the deployment path, then monitoring and backup. That sequence explains how the platform stays operable.

Open architecture

Case studies

Walk through concrete platform decisions with problem, constraints, implementation, and operational outcome.

Projects

Overview of the live platform, DMA, AWStats reporting, migration work, private hosting, and the planned vulnerability-management project.

Open project overview

Architecture

Routing, service boundaries, public vs. private surfaces, and why the platform remains intentionally single-host.

Review architecture

Monitoring and Logging

How metrics, uptime checks, alert rules, and short-retention logs provide visibility without turning the VM into an observability cluster.

Open monitoring details

Backup

What is backed up, what is excluded on purpose, how offsite sync is prepared, and how restore remains procedural under pressure.

Review backup strategy

Lessons Learned

Trade-offs that changed once the platform moved from planning to real services and real operational constraints.

Accessibility Review

Baseline checks for keyboard flow, focus visibility, mobile tables, and JavaScript fallbacks across the public surfaces.
