Hi, I'm Lennart 👋

I'm a product-focused full stack engineer with years of experience in leading large-scale open source projects and shipping high-quality work to millions of users. Adept at building delightful, inclusive, and well-documented solutions to customers' needs.

I'm currently working at Mastra. Previously I worked at Clerk, Netlify, and Gatsby.

I enjoy working on open source projects & making the web more inclusive through them. My OSS code has been used by thousands of people & I regularly share educational content in the form of posts, presentations, and videos.

You can also find me on Bluesky at @lekoarts.de or on Mastodon at mastodon.social/@lekoarts.
