🧭 About

name:     Mustafa Erbay
location: Bursa, Türkiye 🇹🇷
work:     System architect & infrastructure engineer (since 2006)
side:     Indie hacker · self-hosted everything · 0 managed cloud services
writing:  Bilingual tech blog — TR + EN, 730+ articles, FAQ-rich
focus:    Production war stories · DevOps reality · Career honesty
fueled:   Strong Turkish coffee ☕ · `tail -f /var/log/*` · `htop`

20+ years in production. Lived through OOM kills (5–7 GB heap with 7.6 GB RAM), Docker disk fires (33 GB build cache + 23 GB unused images), kcompactd %92 CPU SSH lock-outs, and a self-inflicted CI runner cleanup that killed itself. I write about what actually happens in production — not the marketing slides.
