Konsulenten skal have dyb forståelse af, hvordan EF Core internt fungerer, herunder change tracking og optimistic concurrency, samt kunne forstå og skrive SQL - fx indexes, snapshot isolation, rowversion, og kunne læse og optimere baseret på en query plan - Erfaring med systemudvikling, og oversættelse af forretningsmæssige krav til kode-implementation - Erfaring med integrationer fra begge sider: både integrationer mod 3. part, og udstilling af integrationsflader til 3. part (herunder retries, outbox-pattern, kontrakt-bindinger og versionering, auth m.v.) - Har arbejdet med sikkerhed, herunder trusselsmodellering, IdP, mTLS, kryptering, RBAC m.v.
