Hi, I'm Marvin Hagemeister TypeScript/JavaScript developer

I'm best known for my work on preactjs, a 3kB react-like library that is used in Google AMP. Besides that I've worked on several large scale enterprise react applications for both national and international clients in the insurance, automotive and banking industry.

Besides coding, I enjoy speaking at various international
conferences or local meetups.

Let's work together! Reach out
