Writing tips
- State scale honestly (requests/day, data volume) — it's the first thing senior reviewers scan for.
- Name the failure modes you handled: retries, idempotency, and rollbacks signal production maturity.
- Include one bullet on cost or efficiency; backend budgets are a hiring manager's daily pain.
- Match the job ad's database and queue names exactly — 'Postgres' vs 'PostgreSQL' can miss a filter.
