Hello There, I'mWolfgang Gahlnbäck

DevOps Engineer with a background in web development who .

Welcome to my World

A world where code is not just a tool, but a foundation. I build solutions that run reliably, scale well, and stay manageable — where every script saves time. Below are three areas where I’ve developed and applied this mindset in practice.

DevOps & Infrastructure

  • Linux servers: management, updates, SSH, access control
  • Automation: Bash scripts for deployment, backups, system maintenance
  • Containerization: Docker images & Nginx proxies (native & containerized)
  • Authentication: Keycloak integration with OpenID Connect
  • CI/CD: Git workflows, automated releases and processes
  • Stability & Security: monitoring, performance analysis, fault prevention

Web Development (PHP)

  • Back-end: Laravel, WordPress, Nextcloud and legacy PHP
  • APIs & Interfaces: JSON output, server-side integrations
  • Databases: MariaDB, MySQL, PostgreSQL, SQLite, SQL tuning
  • Code Quality: PHPUnit, Composer, Git, Xdebug debugging
  • Frontend: adaptation and enhancement using JavaScript, HTML, CSS/SCSS
  • Performance: caching, bug fixing, server-side optimization

Hardware & Engineering

  • System building: assembling and repairing servers & PCs
  • Mining rigs: ventilation, power supply planning, maintenance
  • Networking: cabling, fiber optics, routers, switches
  • Communication: setting up IP telephony, PBX systems, VPN
  • Electrical Systems: planning, implementation, and maintenance of power infrastructure for stable operation under heavy load
  • Crypto Technologies: trading and mining with custom-built rigs

AboutI design reliable infrastructure backed by code

Reliability starts with an architectural approach. Bash scripts, containers, and configurations turn the system into something manageable and reproducible. Services are deployed via configuration, and processes go through automation.

Application development experience is not a closed chapter but a built-in tool. It helps to understand how code thinks and to design the environment in tune with its logic.

My SkillsAutomation is respect for your own time

If an action is repeated a second time — it’s already a reason to write a script. That’s how order is born: from routine to a controlled process.

Every instability is a chance to design architecture. A problem is an entry point to a systematic solution.

Approach to WorkWhen details matter and results are predictable

Technical tasks become manageable processes. Clear logic, mature DevOps practices, and quality control ensure a stable, transparent, and reliable system.

  • Infrastructure under supervision

    Process support in any scenario: failures, updates, scaling — without downtime and with controlled system behavior.

  • Engineering precision

    No detail goes unnoticed: all configurations are carefully reviewed and implemented strictly according to architectural requirements.

  • Regular updates, backups, and Git

    Your data is always safe: code versions are tracked, backups are automated. Any change can be rolled back, every state can be restored.
