In a recent hackathon, Team Subarashi created an innovative e-learning web application called Senpai, which connects programming mentors and mentees for one-on-one tutoring, utilizing Vonage Video API to provide a seamless experience for users interested in learning frontend technologies. The app was designed to streamline the process of scheduling appointments, video chat, screen sharing, and collaboration, making it suitable for virtual classrooms or tuition centers. By leveraging MongoDB, Express, React, Nodejs, Docker, and the Vonage Video API, Senpai offers a unique solution for programmers to provide one-on-one tutorial services, allowing users to learn frontend technologies in an interactive and real-time environment.
