• Drove organisationen mod kontinuerlig levering parathed i ældre systemer ved at forbedre CI/CD rørledninger, definere bygge og implementering standarder, og containertjenester (Docker + Kubernetes)
• Leveret interne tekniske sessioner og videndeling begivenheder til at tilpasse teams til performance tuning, observabilitet og ikke-funktionelle krav

• Designet og implementeret komplekse backend funktioner i Java og Spring Boot, bryde store proces strømmer ind pålidelige mikrotjenester
• Ejede backend-tjenester end-to-end: datamodel design, API design, persistens lag (Hibernate/JPA), test og implementering parathed
• Koordineret integration med andre mikroserviceejere for at opretholde interoperabilitet og data-konsistens på tværs af platformen
• Drove kode kvalitet gennem ren kode praksis, CI/CD, og test-drevet udvikling (JUnit); skrev retningslinjer og onboarding materialer
• Integreret autentificering og sikkerhed lag med OAuth2 og bidrog til udrulning af cloud-indfødte installationer ved hjælp af Docker og container orkestration
