Hi there, I'm Johannes! I've been building products and open source tools for over a decade including:

• Prisma, a next-generation TypeScript ORM
• GraphQL Playground, a GraphQL IDE (donated to GraphQL foundation)
• Contentlayer, a build tool for your site content
• Chromeless, a headless Chrome automation tool (before Playwright existed)

I'm currently focussed on

• Building LiveStore: Next-generation state management framework based on reactive SQLite and built-in sync engine
• Researching and advocating local-first software development
• Running the localfirst.fm podcast
• Helping developers write better TypeScript with Effect
• Maintaining and contributing to OSS libraries

Recent Projects

• LiveStore
• Code Syntax Highlighter

Thank you

Your support means a lot to me and helps me to continue working on my projects. Thank you so much!
