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 work. 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 core of our app is the web framework Django 3.1. and everything runs in Python 3.8. Our frontend is currently built in HTML 5 using jQuery. For more complex components we use React combined with the Redux framework for state management. 

Our servers run in Rackspace cloud on Ubuntu servers which we configure using Ansible. The combination of Nginx and uWSGI proved to be a reliable way to serve applications. We cache temporary data in Memcached and Redis. PostgreSQL 9.6. takes care of our database transactions. For background tasks processing we use RabbitMQ in cooperation with Celery. 

We manage our source code using Git and access it through GitLab. We use Gitlab CI to manage our continuous integration process. All of our builds run isolated in Docker containers. To run and analyze our automated test suite we use py.test test runner. To keep the code consistent, flake8 ensures our internal code style is in place. Documentation is managed and built using Sphinx. Our applications are packaged and distributed as Debian packages and deployed using Fabric. 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. 

Are you the one we are looking for?

We’re interested in knowing which programming languages you have experience with and what kind of projects you worked on. Also, we’ll be happy to check out your projects on GitHub or some other samples of your work.
