• The idea of developing a mobile terminal APP for mining pools was first proposed, and the construction of the BTCC mining pool ecosystem was proposed. The aim is to provide one-stop service for miners, an APP to solve all the needs of miners. • Set up the BTCC mining pool mobile development team, select development framework and build development environment based on development cost, development time limit and engineer's main technology stack. • Develop Res Native as the main development framework to develop iOS/Android mobile app, coordinate development progress, and participate in the development of major functions • Embed user data analysis tools to obtain APP operational data • Responsible for reviewing the code, ensuring project quality, and being responsible for the final submission of the product
