Dominik Dorfmeister, known online as TkDodo, is an Austrian software engineer, core maintainer of TanStack Query (formerly React Query), and one of the most influential voices in the React ecosystem. Based in Vienna, he works as a Frontend Engineer at Sentry while helping shape how millions of developers approach server state management. His blog at tkdodo.eu - built on the philosophy that 'if I get a question three times, I write the answer down' - has become essential reading for React developers worldwide. With over 3.5 years maintaining TanStack Query (which now appears in nearly 20% of all React applications), conference talks from Berlin to Paris, and a co-created official course at query.gg, Dominik bridges the gap between library internals and everyday developer experience.
Scott Tolinski is a web developer, podcaster, and educator best known as co-host of Syntax.fm - widely regarded as the most popular web development podcast in the world. He founded Level Up Tutorials in 2012 after a breakdancing injury sidelined him, building it into a library of 2,000+ video tutorials with 350,000+ subscribers before it was acquired by Sentry. Now serving as Executive Producer at Sentry, Scott co-hosts Syntax alongside Wes Bos, releasing two episodes per week covering JavaScript, SvelteKit, CSS, and modern web development. Outside the keyboard, he is a dedicated B-boy (breakdancer) and avid snowboarder based in Denver, Colorado.
