    Maintaining microfrontend.dev

    I am a JavaScript developer who's worked in the industry in multiple roles, from frontend engineer to architect for a couple of decades. I'm also an OpenJS foundation CPC member, a Node.js contributor and now work in the role of Lead Product Architect for JavaScript developer tools and experiences at Microsoft Azure. I saw the potential of micro-frontend architectures early on, and was one of the movement pioneers starting as early as 2019, publishing content about my real life experience decoupling and recomposing enterprise-grade platforms. I now maintain https://microfrontend.dev as the most comprehensive resource in the space. I'm also the author of "What is JavaScript? A resource for cross-functional teams" with O'Reilly.
