Education & Experience
Experience
I worked as a Software Engineer, Staff Engineer and Principal Engineer for various companies of different sizes. Some of them have been as small as a handful of people, others have been as big as 15k people. I have seen companies grow from cozy 35 to 1000 employees. I have experience in the education, finance as well as build and design domains. Some of the companies I worked for are Babbel, Solaris and Autodesk.
I worked on "old-school" monoliths and "fancy" microservice architectures with Kubernetes and AWS Lambda. My focus has been mostly around backend development in Ruby, Go and Node.js as well as system design. A major part of my work has been designing and implementing APIs (REST & GraphQL) and background as well as data processing. I learned a lot about highly available systems as well as observability with metrics, alarms, dashboards and logs. I worked with different SQL and NoSQL databases like MySQL, Postgres, Redis and DynamoDB. I have used the AWS Cloud in recent years.
Since 2017 I have gained lots of experience in leading teams of 5 to 15 members. During that time I picked up knowledge in the areas of leading, mentoring and sponsoring others. I had an impact on people around me that were promoted from Junior Engineers to Senior and Staff Engineers.
