Clientside is a platform I began developing in December 2022 to help frontend developers prepare for job interviews. Launched as a practical resource, it has been used by over 2,500 web engineers to practice JavaScript exercises and React projects based on real interview questions from top tech companies. Clientside features an interactive code playground, instant feedback, and full-code solutions with walkthroughs. In August 2023, the platform was acquired by a third party.
