Project description:

The system is designed for management within teams and cyclists training sessions. It allows users to plan seasons, communicate with each other, organize meetings and track the location of team members in real time

The app was released in 2016 in React Native. and we arrived in 2017. So it was a lot of legacy code for us at this moment, with some components reaching 1500 lines of code without any comments and explanation of the functionality. We had a pretty tight deadline of 4 weeks to sort out the codebase and application to go live. After successfully completing this task, we have embarked on another big iteration of releasing version #2 with completely new designs and new features. We are responsible for both API development, web admin and mobile applications.

While redesigning the application we were short on time so decided to create a bundle of custom components that will be used all over the project. As a base we've utilized material UI as it allows to use all major components out of the box and is highly customizable allowing us to define high-level theme for the whole application.

Responsibilities:
  • Conducted code audit and implemented measures to improve code quality
  • Assisted in onboarding new team members by introducing them to code style and guidelines
  • Maintained regular communication with product owner, team members, and project manager to ensure clear specifications
