Database Administrator (DBA) Resume Example
A database-administrator resume must prove safe operation across availability, performance, backup, and recovery. This example covers PostgreSQL and MySQL HA, Patroni, EXPLAIN ANALYZE, connection pooling, backups, WAL archiving, and PITR without reducing DBA work to one engine.
Use it to document estate scale, change controls, failover behavior, tuning evidence, and restore validation for the database platforms you actually managed.

How to Write a Database Administrator (DBA) Resume
Open with database engines, estate size, transaction load, and availability obligation. Keep PostgreSQL and MySQL responsibilities distinct while showing the common operational discipline.
For performance, state the query or connection problem, diagnostic method, index or rewrite action, and measured outcome. EXPLAIN ANALYZE and pg_stat_statements matter because they explain how the diagnosis was made.
Treat backup as incomplete without recovery evidence. Describe pgBackRest or other source tooling, WAL archiving, retention cadence, PITR tests, and failover drills using only verified targets.
Maintained databases, ran backups, and improved SQL performance.
Manages 12 PostgreSQL clusters (5TB total, up to 10K TPS peak) supporting core banking for 500K customer accounts with 99.99% uptime SLA.
What to Include in a Database Administrator (DBA) Resume
Include PostgreSQL and MySQL estate scope, HA/replication, performance analysis, indexing and pooling, backups and PITR, monitoring, upgrades, cloud databases, automation, security/availability obligations, and relevant DBA certifications. Add a certifications subsection because this source includes EDB PostgreSQL 14 Associate Certification; AWS Certified Database – Specialty; Oracle Certified Associate — MySQL; on your resume, list only credentials you actually hold and preserve their official names.
