🏗️ Infrastructure Architecture
Design principles I follow:
- 🔁 Multi-region by default — active-active where possible, active-passive with DNS failover where required
- 💾 Immutable backups — automated snapshots + cross-region replication + periodic restore drills
- 📜 Git as single source of truth — every production change goes through a reviewed commit
- 📊 SLO-driven operations — error budgets, burn-rate alerts, post-mortems for every incident
