Summary

Currently interested in iterative work, declarative infrastructure and continuous integration. Worked on many different aspects of software from sending binary data to USB printers to orchestrating microservices with Kubernetes & Terraform.

Experience

Platform Engineer

As a part of the platform team I help building and maintaining the AWS infrastructure in Terraform and monitoring our services in Kubernetes, as a healtcare platform uptime is everything. Biggest achievement was transforming our platform to Kubernetes to help us release with less friction.

Platform Engineer

Dolittle is a PaaS for building event-sourced microservices. I started as a developer on the Dolittle open-sourced event-sourcing library and runtime, but eventually became part of the platform team for hosting solutions built with the Dolittle library. I built platform automation and an API with Go to provide self-service capabilities for our Kubernetes cluster & Azure hosting. I greatly improved the documentation of the library, from the user taking hours to just minutes to have a local microservice setup.
