My main project at the moment is skilj, a Rust library for event-sourced applications on Postgres.
I've been doing Java and Kotlin for most of my career. Doing Clojure and Rust in my free time, and dabbled a bit with Node.js. I have experience with several types of API's. Using REST based on OpenAPI, GraphQL, and async API's based on Kafka in formats like Protobuf and Cloud Events. For BKES I used gRPC. I created and maintain a Rust library to use schema registry schema_registry_converter.
I've presented on using GraphQL with Apache Kafka at GraphQL Summit 2019. I also presented at Kafka Summit 2020 and Kafka Summit 2021, and some others. I'm trying to write more blogs, I've written some at Dev.to. There are also two blogs I wrote in cooperation with Confluent, using Rust with Kafka and using GraphQL with Kafka. There is also one about the background of the Rust library on the Open Web blog page.
You can find me on Twitter and LinkedIn. Currently I'm working as a software engineer at Alliander.
I also track my bass progression, or stagnation here.
