Jonas Schmedtmann

Jonas Schmedtmann is a web developer, designer and online teacher based in the Algarve in southern Portugal, and one of the most popular web development instructors on Udemy. More than 2 million students have taken Schmedtmann's courses, which hold an average rating of about 4.7 out of 5 across hundreds of thousands of reviews and are also used by company teams through Udemy Business.

Schmedtmann started coding more than 20 years ago with a thick book on HTML, CSS and early JavaScript, and later freelanced as a web developer while studying for a master's degree in engineering. Frustrated by outdated blogs, confusing tutorials and weak online courses, Schmedtmann set out to build the courses that were missing, combining a love of computers, teaching and learning.

The catalogue is deliberately small and deep: The Complete JavaScript Course (over 1 million students), Build Websites With HTML and CSS, The Ultimate React Course, The Complete Node.js Bootcamp, Advanced CSS and Sass and a Web Dev Crash Course, with a Practical TypeScript course announced. Every course is designed, recorded and taught by Schmedtmann alone, built around detailed explanations, polished real-world projects such as Omnifood, Forkify, Natours and The Wild Oasis, and diagrams that show how each technology works under the hood. The positioning today is that deep fundamentals are what make developers effective with AI coding tools.
