Get to know me

Hands-on ICT professional with a background in software development and a growing specialization in application and systems administration. Comfortable across the stack - from configuring business-critical applications and workflows to managing Linux servers and containerized environments. I pick up new tools fast, work independently, and design my own homelab infrastructure for the fun of solving the same problems I handle at work.
