Technologies we use

What we offer

• We create a front-end based on our own style-guide - we care about the consistency and quality of our websites

• We are not afraid of new technologies - we are happy to use pure JS, but we also have React, Angular, Vue, and we serve everything using Node.js. We also have a private register of npm

• We care about the performance of our solutions both on the browser and server side

• We create large-scale micro frontends (800+ components), microservices - for real (1000+) and scale for real (60k + rps on business data bus)

• We use, depending on the teams and needs, the latest versions of Java (from 8 upwards), Scala, Kotlin, Groovy, Go, Python, Spring, Reactive Programming, Spark, Hadoop, Mesos, TensorFlow

• In our company, Big Data is a few petabytes of data, and Machine Learning is used productively

• We use Code Review, Continuous Integration, Scrum / Kanban, Domain Driven Design, Test Driven Development, Pair Programming depending on the team

• We have an internal ecosystem based on self-services and widely used tools such as Docker, Consul, Kubernetes or GitHub. Thanks to this, in the first days of work you will be able to create software in the language, architecture and scale that will be limited only by your idea and imagination

• We actively participate in the life of the largest groups of users related to technologies in which we work (Java, Python, Devops) in Poland, organizing trainings / workshops and presentations in Poznań, Warsaw, Toruń and Kraków

• Technological autonomy: you choose the technology that fits the problem (no consent from all saints). Then you are responsible for it

• We have an environment combining our two private Data Centers (10,000 servers) and a Public Cloud (Google Cloud and Microsoft Azure)

• We create over 60 open source projects, several thousand stars on github

• Our employees regularly go to conferences in Poland and abroad (Europe and the USA), each team has a budget for training and books, if you want to develop, we will always help you.
