I am a software engineer with 8 years of professional experience in statically typed languages (mostly Java, but recently Typescript as well) and a keen interest for dev-ops, testing and monitoring. In my work, I like putting emphasis in quality, flow and fast feedback, while focussing on adding value to the end customer iteratively by starting small and learning fast. I have experience working agile in software teams as well as an individual contributor. I really love working with clever people and working on tricky problems but I also like adding value to my work by being involved in cross team management and requirements refining.

Project history

02/2020 - Present
Software Engineer (Remote)
Anyfin AB (Banks and financial services, 10-50 employees)

Worked remotely, reporting directly on the CTO on the following tasks:
  • Improvement the company's systems reliability  by implementing  a monitoring solution for Anyfin's production Kubernetes cluster, using Prometheus and a real-time dashboarding solution using Grafana.

10/2017 - 02/2020
Software Engineer - Merchant Operations
Klarna Bank AB (Banks and financial services, 1000-5000 employees)

I was really happy to work with a highly energetic team of 5 engineers with a strong focus on delivering high quality results in the post-purchase order management domain on the following fun challenges: 
- Development of Klarna's (public) Order Management API which is handling succesfully more than 10M API calls every week. The Order Management API ecosystem consists of around 15 different Springboot/Dropwizard micro-services, that are glued together with Kafka and REST, deployed in AWS.
- Development of the orders app in the Klarna Merchant portal. 

09/2015 - 10/2017
Software Engineer - Merchant Onboarding
Klarna Bank AB (Banks and financial services, 1000-5000 employees)

​​​​​​I had the joy of working in a 5 member team of amazing engineers with a strong product focus on the following problem spaces:
  • Replacing a manual and error prone merchant onboarding flow, with a fully automated solution of a group of java (Dropwizard) micro- services deployed in AWS.
  • Creation of an API-heavy onboarding flow for merchants (internally branded as "native partner" onboarding flow) that were onboarded to Klarna via e- commerce platforms (like EKM in UK or mijnwebwinkel in NL).

03/2012 - 09/2015
Android Software Engineer
Apegroup AB (Internet and Information Technology, 10-50 employees)

Worked with building Android apps for some of Sweden's most innovative brands, for example

  • ICA, the leading grocery retailer in Sweden
