For more than 8 years we have been working with this customer. It is a big account, and our project is the youngest part of it. It started in 2019. Be sure, we are continuously working on new features and the project is to be ongoing.
Our project is one in a chain that makes network rollout worldwide possible. We build an integrations part of 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.
Overall, this is a huge project with massive amounts of data, with more than 150 servers as the infrastructure, and some servers are 96 core/1TB RAM monsters.
Our project is not just an interface but also a cashing/search solution that allows users to quickly search among huge 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.
Some of the foreseeable future tasks: implementation of faster cache update cycle via Apache Kafka, switching to ELK stack for logging, switching to HTTP/2 in the UI.
About the team: 4 Developers, 2 Test Engineers, and a PM. We are also working as one team with another sub-contract company, and there is a Scrum Master, Architect, and 3 Developers from customer’s side.
