How we work

For easy project management and communication we use Trello and Slack. We’re not wasting time on endless meetings and we set reasonable deadlines for our tasks. We work in an open and easygoing atmosphere. Our work is challenging enough and we're always striving to move forward so you’re definitely not going to be bored.

The backend of our app runs in Python 3.8 and uses the Django 3 web framework.

Our frontend uses React combined with the Redux framework for state management, while some parts of the app are built in HTML5 using jQuery. Our new UI kit helps us to achieve a consistent look of our UI across the entire app, with all UI elements defined in the Tailwind CSS framework.

Our applications are fully Dockerized, managed via Kubernetes and running in the Google Cloud Platform. We use Redis to store our cache and Celery queues state for background processing of tasks. Our main database is PostgreSQL, complemented by MongoDB for storage of our logs.

We manage our source code using Git and access it through GitLab. We use Gitlab CI to manage our continuous integration process including deployment to the cloud. To run and analyze our automated test suite, we use py.test test runner. To keep the code consistent, Black, Flake8 and Mypy ensure our internal code quality and style are in place. Documentation is managed and built using Sphinx, partially auto-generated from the code. In production, Rollbar helps us with tracking errors and performance metrics.

All the technologies we use are open source and we frequently contribute to various projects. We use mainly Python but we’re experimenting with some of the newest technologies such as Go.
