Wolt, a technology company specializing in local commerce and delivery logistics (part of DoorDash), shares how Kotlin has become a core part of their backend systems and engineering culture.

In this case study, Andrei Nevedomskii, Kotlin Competence Lead at Wolt, explains:

• The transition from a Python monolith to Kotlin microservices
• Why Kotlin’s type safety, concise syntax, and Java interoperability make it a strong choice for backend development
• How Wolt teams use both Ktor and Spring with Kotlin for flexibility and performance
• The role of Kotlin in improving developer productivity, reliability, and time to production
• Scaling to 150+ engineers and 150+ active repositories powered by Kotlin
• How internal Kotlin tools now allow launching services in minutes instead of days

Wolt operates in 30 countries with over 50 million users, and continues to invest in Kotlin for both backend and mobile. They are currently hiring Kotlin engineers in Finland, Sweden, and Germany.
