Naj

Technical portfolio focused on homelab infrastructure, Docker, networking, databases, dashboards, automation, and engineering support systems.

I build, troubleshoot, and document practical IT and engineering solutions using real systems, self-hosted services, and production-style lab environments.

Most of my technical work is self-taught and built through hands-on troubleshooting, lab testing, documentation, and practical problem solving.

I use available tools, including official documentation, community references, and AI-assisted research, to speed up learning and validate ideas. Final implementation, testing, and documentation are based on my own environment and hands-on work.

Focus Areas

  • Docker and containerized services
  • Linux and Windows administration
  • OpenWrt, firewall rules, VPN routing, and local DNS
  • Unraid-based homelab infrastructure
  • PostgreSQL, MariaDB, Redis, and application database separation
  • Nginx Proxy Manager, Authelia, and private service access
  • Grafana, InfluxDB, Flux queries, and dashboard optimization
  • Power BI, DAX, maintenance KPI reporting, and data modeling
  • Power Automate workflows and Adaptive Cards
  • FreePBX, SIP testing, softphone access, and VPN-based telephony
  • SCADA/OT support concepts, remote monitoring, and operational dashboards

Selected Projects

Homelab Infrastructure

A self-hosted lab environment used to test Docker services, reverse proxy routing, database hosting, DNS filtering, secure access, and backup practices.

Docker, PostgreSQL, and Redis Service Model

Designed a cleaner container backend model where applications use dedicated databases and users while sharing central PostgreSQL and Redis services.

Technical Guides

I maintain Markdown-based guides for repeatable troubleshooting and setup tasks.

Lab Notes

My lab notes are used to test and document practical designs before applying similar patterns to real environments.

Public-safe topics:

  • Homelab architecture overview
  • Private service access model
  • Docker update strategy
  • Local DNS and reverse proxy design
  • VPN access model
  • Backup and recovery planning
  • Database separation per application

Sensitive details such as IP addresses, hostnames, credentials, firewall rules, and private subdomains are intentionally excluded.

Working Style

I prefer:

  • Simple designs that are easy to maintain
  • Clear documentation
  • Reusable commands and checklists
  • Secure-by-default access
  • Private services behind authentication
  • Manual validation before production changes
  • Understanding the root cause instead of only applying quick fixes
