Zero-downtime Docker deploys with health checks
A small bash script that pulls, health-checks, and rolls back automatically — no docker-rollout, no Kubernetes, just bash.
System Engineer knowledge hub
Real-world guides, tools, and lessons from production system engineering work — built with AI, shared with everyone.
nuteo.info is where I document everything I learn as a System Engineer — from setting up servers at 3am, to automating deployments, to debugging mysterious network issues that only happen in production.
This site is a knowledge base, a portfolio, and a teaching hub — all in one.
🎯 What’s here
- 📁 /work/ — Production projects I’ve shipped
- 📚 /guides/ — Step-by-step how-tos for sysadmins
- 🛠️ /tools/ — Scripts, configs, and CLI arsenal I actually use
- ✍️ /blog/ — Field notes, postmortems, and lessons learned
🤖 Built 100% with AI
Every page, every line of code, every config — assisted by AI. This is my experiment: can a system engineer run a full knowledge site without writing a single line manually?
Spoiler: yes, and it’s faster than I thought.
