О проекте

The project is in the Telecom domain and is one in a chain that makes network rollout worldwide possible. We are building a new user interface from scratch for the workflow management system that is the backbone of the business with almost 100,000 employees. This system is used to manage thousands of projects related to mobile network rollouts from Japan to Mexico.

Our project is the interface and a cashing/search solution that allows users to quickly search among vast amounts of data available in the system. For caching, we use MongoDB with Mongoose ORM.

The backend of our caching solution is written in Node.js/Express, ESLint with Google’s rules; Jest for unit tests; GitLab for code reviews.

We are gradually rewriting the existing codebase to leverage the functional approach, using Ramda.js as our main helper library.

Overall, this is a massive project with massive amounts of data, with more than 150 servers as the infrastructure, and some servers are 96 core/1TB RAM monsters.

About the team: 4 Developers, 2 Test Engineers, and a PM. We are also working as one team with other sub-contract companies, and there is a Scrum Master, an Architect, and 3 Developers from their side.
