PROJECT

DWANGO PROJECT

Dwango Co., Ltd. e-learning system "N Preparatory School"

We provided systems engineering services to help develop an online cram school service for the internet generation, run by Dwango Co., Ltd. Dwango planned, designed, and implemented the service, while Vareal provided engineering resources for a certain period of time to support front-end and back-end development.

This app combines live lessons from “N Preparatory School,”
teaching materials (workbooks and reference books), and a Q&A system (question board). Each has various functions to improve the efficiency and quality of your studies.

Vareal supported the development of a portion of the backend using Ruby on Rails (function creation, performance improvement suggestions, stress testing, etc.) and the frontend using TypeScript (operation and modification of a cross-platform Web View application). We provided development resources
by forming a team of six people: one person for the frontend, a Japanese PM, a Vietnam Bridge SE, Japanese and Vietnamese engineers, and a QA for the backend.
