Our Tools

We constantly use bleeding edge technology and at the same time, we endorse experimentation. Our internal monitoring systems make sure all our experiments are performed in isolation so hey, go nuts!  

This is an outline of our current tech:

  • Our web app is in ReactJS using Redux and supported by NodeJS

  • Our Back end is in PHP using Yii, Laravel, and lumen

  • We use ReactNative for our mobile app

  • All our apps are dockerised

  • Our servers work on Kubernetes - the master of the universe!

  • We like microservices.  It is our way to move from a legacy monolith to a Services Oriented Architecture and to modernise our stack

  • We like serverless technologies even more

  • We use databases of all sorts to suit our needs: MySQL, Aurora, ElasticSearch, Redis, DynamoDB.

  • Data Science is our way to the future! Our projects run on Java and Python and also consume a number of third-party tools.
