  Stockholm, Stockholm County, Sweden At Klarna I'm working with the order management problem space. My team is responsible for building and running the systems that allow merchants to do post purchase operations on their orders. We offer a REST API and a web app in our merchant portal as well as many internal peripheral services.

My team is responsible for building and running the systems that allow merchants to do post purchase operations on their orders. We offer a REST API and a web app in our merchant portal as well as many internal peripheral services. Most of my work is related to our java back-end services but I'm also at times involved with the front-end app. Our back-end services are build as containerized Spring Boot apps and runs in AWS in our in-house abstraction on top of AWS ECS. We manage our own jenkins pipelines through Jenkinsfiles. We make heavy use of Kafka, AWS SQS, AWS DynamoDB, PostgreSQL in RDS and Aurora. We manage most of our infrastructure by using infrastructure as code via Terraform. We also own the public documentation of our products and API specifications. The team is quite autonomous, we work with a scrum like setup of one week long sprints. Our practices include daily stand-ups, weekly planning and grooming of upcoming work, and bi-weekly retrospectives. I'm also involved with the security awareness group with the goal of helping my team and adjacent teams to keep up with security best practices. We hold regular threat modelling sessions where we try to find possible threats and mitigations. This work is influenced by the STRIDE threat modeling methodology. Show less

  Berlin, Berlin, Germany In my time with Klarna in Berlin I worked in a team that was responsible for specialized payment integrations. We built containerized Spring Boot back-ends backed by AWS RDS MySQL and PostgreSQL datastores. Our first project was to migrate a set of on-prem payment integrations to AWS. Those were implemented in an in-hosue web application framework and had to be migrated to Spring Boot. After migrating the existing services I was involved with projects to build new integrations… Show more In my time with Klarna in Berlin I worked in a team that was responsible for specialized payment integrations.
