PROFILE
Owen Chen
Worked on the percona/percona-server-mongodb repository, delivering four features and a bug fix over three months focused on security, reliability, and usability. Implemented immediate privilege change application for authenticated sessions and enabled Queryable Encryption prefix/suffix search by default, both reducing operational friction and enhancing security. Consolidated and streamlined FLE metrics reporting, removing obsolete metrics to improve performance and reporting clarity. Addressed reliability by ensuring graceful shutdown of the Mock OCSP Responder on SIGINT and strengthened OIDC client URL validation. Leveraged C++, Python, and backend development skills, with attention to authentication, database management, feature flag implementation, and security best practices.
