DevOps skills

• Writing Postmortems — free — Turns an incident into a blameless postmortem with a timeline, contributing factors and owned action items, using language that describes systems rather than assigning fault. Use after an outage, a data loss event, a failed deploy, or when the user asks for an incident report or RCA.
• Reviewing Database Migrations — $5.00 — Reviews a schema migration for locks, downtime and irreversibility before it reaches production, and rewrites unsafe steps into an online sequence. Use when reviewing a migration or DDL change, adding a column or index to a large table, renaming or dropping anything, or when a deploy needs zero downtime.
