Projects

02/2015 - Size Guru

Period: 02.2015 – current Customer: Size Guru Role: CTO & Co-Founder/Lead Developer/Technical Architect Description: Heading up the technical side of a start-up company developing a widget aimed at web

shops, which help customers find the right fitting shoes. The widget is integrated into the web shop as a JavaScript library and run as an AnguarJS application on AWS. The backend is based on Spring Boot and exposes all its services through a REST interface. Various AWS api’s are used for optimization and/or access to AWS products, such as Amazon SES (Mail). Both the frontend and backend is run using Tomcat on AWS Elastic Beanstalk.

09/2011 - Independent

Period: 08.2015 – current Customer: Skatteetaten (Norwegian tax authorities) Role: Lead Developer/Technical Architect Description: Worked on a project for transforming Skatteetaten’s existing integration layer from a

classic SOA architecture, based on Oracle technologies, to a range of micro services. The requirement was to improve time to market on service releases, combined with a need to lower license costs. The task was to split up and convert all existing Oracle OSB and Oracle BPEL as well as implement a number of new services, using a range of open source technologies e.g. Spring Boot and Camel. In order to improve time to market for a service we aimed at developing a module catalogue in order to ensure fast turn arounds from request to go live as well as quick isolated releases. The services worked as a middle layer and entry point to +400 different systems within Skatteetaten, for all external systems.

My primary role was to head up the technical side of the project, assist in technology decisions, service architecture, and environment setup and tuning as well as mentoring in-house staff on the new technology platform.

Period: 02.2015 – 08.2016 Customer: Alm Brand (Danish insurance company) Role: Project Manager/Lead SOA Developer/Technical Architect Description: Headed up a project for Alm Brand transforming parts of their existing SOA

architecture to the micro service style. The project was derived from the project KAKAO. The goal was to transform both existing as well as implement a number of new services and expose them as a range of company generic micro services. All of them developed as completely self-contained and compliant with the common understanding of the micro service style, within Alm Brand. Bottom line was to develop the services to gain more flexibility in terms of elasticity, faster isolated releases and initiate a desire to move parts of their backend to the cloud (Amazon Web Services).

Primary role was to head up a team of developers and assist on technical issues and architecture. Define a micro service framework to ease the development and define guidelines for the services.
