Monteurzimmer Nedic

Monteurzimmer Nedic

Digital booking platform for contractor accommodations – live and in use by construction companies and students. Manages room availability, accepts booking requests and presents the property with a media library and contact function. Next.js was chosen as the framework since SSG delivers fast load times without server overhead – Directus handles content management without vendor lock-in.

Production Infrastructure

Production Infrastructure

Self-built and managed multi-app production infrastructure based on Ubuntu 22.04 and Docker. Includes centralized reverse proxy management, SSL certificates, CMS, monitoring and PostgreSQL backups – fully accessible via HTTPS subdomains. Docker was a deliberate choice to run all services in isolation, reproducibly and independently of one another – GitHub Actions automates the entire deployment cycle from staging to production.

Target group:

Developers and administrators of ned-it.deContent managers maintaining content via Directus CMSDevOps personnel monitoring the infrastructure

Features:

Server hardening: SSH key authentication, disabled root login, UFW firewall, Fail2banReverse proxy & SSL: Nginx Proxy Manager with automatic Let's Encrypt certificates (HTTPS, HTTP/2, HSTS)CMS: Directus with PostgreSQL database, accessible at cms.ned-it.deMonitoring: Grafana dashboard with Prometheus, Loki, cAdvisor and Node Exporter, accessible at grafana.ned-it.deDocker networks: Isolated networks (proxy, monitoring, directus) for service segmentationProxy management: Admin UI at proxy.ned-it.deBackups: Structured directory for PostgreSQL backups

App Manager

App Manager

Internal application portal for centralized management of a personal application pool. Enables adding, reading, updating and deleting applications as well as reporting and monitoring functions. PostgreSQL was chosen as the unified database layer since all other projects use the same instance – this reduces maintenance overhead and enables cross-project queries.
