In Growbots we build applications using Python and Tornado framework (plus Celery). As data store we use mainly Elasticsearch (NoSQL database) and RabbitMQ as a message queue. We make up a modular system, using the REST APIs to communicate between applications. Among others we use HTML5, JS, ReactJS, Flux and Bootstrap for frontend. We operate in accordance with the Clean Code, we do code review, we use Git, actively use Agile methodologies. Our environments we deploy on Amazon's cloud, we use Docker and Ansible for that.
