Sebastian Soberg enhanced database migration reliability for the navikt/pensjon-etterlatte-saksbehandling repository by implementing safeguards that prevent unsafe migrations, specifically blocking changes when SLUTTBEHANDLING counts do not match expected totals. He updated Flyway from version 27 to 28 to maintain proper sequencing and ensure future migrations remain auditable and traceable. Working primarily with SQL and leveraging his expertise in database migration and versioning, Sebastian’s contributions focused on reducing deployment risk and protecting data integrity during upgrades. His work addressed a critical bug, laying a more robust foundation for future development and demonstrating a thoughtful, detail-oriented approach to backend engineering.
