Web Developer Full-timePartially remote

Danske Bank / Danske Bank Bolig

I was a part of a team developing sunday.dk (now moved to danskebank.dk/bolig), a project that helps people to understand their finances better when finding and buying a new home.

My main focus was on the frontend (React, Redux, Typescript, Enzyme, Webpack, Storybook), but I also contributed to the backend (Node, Express, Swagger, Mocha, Sequelize).

I concentrated on bridging the gap between developers and designers, intending to make sure that we share systematic ways to guide and leverage our collective efforts. This lead to the development of our design system that helps us to stay consistent both in the designs and across the implementation.

Stack: React, Redux, Node, Express, Typescript, PostgreSQL, Elasticsearch, AWS
