Senior Full Stack WordPress Developer & Infrastructure Engineer 路 Katowice, Poland
I have been developing professionally since 2008 and running my own business since 2011. I specialize in WordPress sites with demanding performance and security requirements, and in the infrastructure they run on: Docker, Kubernetes, AWS and CI/CD are part of the same job to me, not a separate discipline.
I run FingerprintWeb.pl, and since 2015 I have worked with Fooz, where I handle demanding deployments, code review and the development of in-house frameworks.
- WordPress infrastructure 路 Kubernetes, AWS, Docker, Ansible, ArgoCD
- Performance 路 Redis, Memcached, OpCache, load testing, database optimization
- Security 路 code and plugin audits, KeyCloak, penetration testing
- Scale 路 multisite, e-commerce with ERP and payment integrations, zero-downtime migrations
- Working with teams 路 mentoring, code review, standards: OOP, GitFlow, linting, CI/CD
Recent years include e-commerce for a cloud computing provider, a sales and e-learning platform for an international photo agency, a large-scale media site, and environment migrations to AWS and Kubernetes.
Tools I use day to day, and projects built outside client work.
| Project | Description |
|---|---|
| ThinkBook Linux Audio | Factory Dolby Atmos tuning extracted from the Windows driver and ported to PipeWire and EasyEffects, with measurements and documentation. |
| Ollama Tray Controller | System tray application for managing the Ollama service. |
| node_modules remover | PowerShell script that removes node_modules directories across a whole project tree. |
Arch Linux, a homelab, local language models running on Ollama, and training in AI and security. I have a particular interest in low-level hardware diagnostics on Linux.
