Portrait of Jon-Mikkel Ryen Korsvik

Jon-Mikkel Ryen Korsvik

AI & Data Engineer at DNB
Oslo, Norway

Data scientist and ML engineer. Generally AI-oriented, with experience spanning development and business.

About

I build data and AI platforms — currently as a Senior Data Engineer on DNB's Insight Factory team, working across Go, TypeScript/React, Kotlin/Quarkus, Kafka, AWS and LLM/GenAI tooling (MCP servers, LoRA fine-tuning, retrieval pipelines).

Before DNB I did applied ML work at Skatteetaten (tax authority) and Fremtind, and full-stack development at NMBU. My master's thesis at NMBU was on abstractive text summarization for Norwegian using transformer models — one of the earlier applications of transformer-based summarization to Norwegian text.

Outside of work: strategy games, guitar, and generally poking at whatever new AI tooling shows up.
