A strong database administrator resume should describe the estate you were responsible for and what you kept running. Highlight instance counts and data volume, the platforms by name, uptime or downtime figures, recovery objectives you actually met, query and batch improvements with before and after timings, and any migration or upgrade completed without data loss. Name your engines explicitly, because PostgreSQL, SQL Server, and Oracle are filtered on separately. Use the examples below to see how to turn database work into clear, results-focused resume achievements.

Projects

Monolith Data Split. Moved 60 TB out of 1 shared database into 12 service-owned stores using dual writes and staged backfills, sequenced by team ownership rather than table size. The migration completed with 0 downtime across 18 months.

Query Cost Redesign. Cut peak query cost 44% by redesigning 3 core schemas and introducing read models for the 8 hottest access paths. The savings came from removing joins the original model had made unavoidable.

Sharding Strategy. Designed and delivered the shard key and rebalancing plan that took a transaction store from 1 node to 8 with no outage. Choosing a key the business could explain mattered more than the theoretical distribution.

Extra-Curricular Activities
