Welcome to Group Technology, where we pride ourselves on engineering solutions and driving Nordea's transformation by providing a holistic technological view and structured understanding of the bank and its surrounding environment to enable the Customer Vision and Business Strategy.

As part of Nordea's 2030 strategic direction, we are modernizing our technology and data estate while accelerating the adoption of AI-enabled capabilities across the bank.

We are now extending the same self-service approach to AI-related integration patterns, including LLMs, MCP, and A2A.
