From Oracle DBA to Postgres contributor with Karen Jex

Who knew an aptitude test could recommend a career as a DBA—and get it right? In Episode 44 of Talking Postgres, PostgreSQL significant contributor Karen Jex walks Claire through her path from Oracle DBA to Postgres consultant, solution architect, and now senior software engineer at Snowflake. My favorite bits: a project switched to Postgres when nobody knew how to install it, faking it as the Postgres expert, and the culture shock of building your own HA and backups. Plus: the warm welcome at PGConf EU 2019 that pulled Karen into the Postgres community; the new Buddy Program at PGConf EU 2026; and moving to the French Alps for the love of mountain biking.

Who knew an aptitude test could recommend a career as a DBA—and get it right? In Episode 44 of Talking Postgres, PostgreSQL significant contributor Karen Jex walks Claire through her path from Oracle DBA to Postgres consultant, solution architect, and now senior software engineer at Snowflake. My favorite bits: a project switched to Postgres when nobody knew how to install it, faking it as the Postgres expert, and the culture shock of building your own HA and backups. Plus: the warm welcome at PGConf EU 2019 that pulled Karen into the Postgres community; the new Buddy Program at PGConf EU 2026; and moving to the French Alps for the love of mountain biking.
