Hi, I'm Lars and I maintain a range of open source tooling that help developers gain productivity when building serverless applications on AWS.

My day job is at mathem.se - Sweden's largest online grocer and some of the projects I maintain reside under Mathem's open source initiative - github.com/mhlabs org.

Some of the more popular projects are:

  • cfn-diagram - CLI tool to visualise CloudFormation/SAM/CDK stacks as visjs networks, draw.io or ascii-art diagrams.
  • evb-cli - Pattern generator and debugging tool for Amazon EventBridge
  • sam-patterns-cli - CLI tool for importing patterns from https://serverlessland.com/patterns into your SAM template among other things
  • sfn-cli - Command line interface for building Amazon StepFunctions state machine definitions
  • StepFunctions Workflow Studio sync - Chrome extension that enables real time sync between StepFunctions Workflow Studio and your local file system

I also publish some proof of concept projects and other fun stuff, like my talking doorbell and functionless URL shortener
