  • GraphQL (Apollo, AppSync), REST API
  • Node.js
  • AWS, Firebase
  • TestCafé, Jest, Detox – we have our own QA
  • JIRA, Github, CircleCI

During recent projects we handled these tech challenges:

  • Fullstack work with AWS and serverless architecture
  • Development of an animated app in React Native
  • Implementation of interface for video calls
  • Work with an offline state of the app (offline first)
  • Optimization of the app for more effective scaling
  • Modernization of code base

What you should know

  • Good knowledge of JavaScript and active usage of ES6 features
  • Good knowledge of TypeScript, Flow is an advantage
  • Advanced knowledge of React.js, any other framework like Vue.js or Angular is an advantage
  • Knowledge of React Native

  • Experience with front-end tools such as Webpack, previously gulp, grunt

What we offer

How we learn and grow

All our developers in the Prague office have an option to use 10 % of working hours for self development to get familiar with new technologies and to improve soft-skills as well. At the same time we learn new things and research what brings the most value to the client. We expect from you to introduce new technologies and methods to team as well.


Technologies we did not use 2 years ago

and learned them

  • AWS – Our DevOps team received a dedicated self-study time to prepare themselves for AWS certification, which they successfully passed and therefore we started to develop first apps with backend on AWS.
  • Vue.js – We are big fans of React, but our group of developers wanted to expand their skills and therefore we could compare the advantages and disadvantages of vue/react.
  • Test café – Our QA engineers needed a testing tool with cross-browser support and within the self study programme they mastered Test café.
  • Node.js – Limited parking spots in front of our office gave us the idea of developing our own parking app, where our developers acquired the knowledge of back-end based on Node.js.
  • ReasonML – We learned this typed language from Facebook on our own product for evaluating user stories, which we use for scrum planning.

Our amazing benefits

  • Dog-friendly office – bring your doggo to the office
  • We’ve got ugo, maté, ice-cream and cookies to satisfy your cravings
  • Regular events (wine degustation, BBQ, foosball tournaments, team buildings)
  • Game room to relax and chill (foosball, ping pong, Xbox)
  • And our greatest benefit was already mentioned – 10% of working hours for self study

Who you’ll work with

Filip Výborný Solution Architect

DevOps king. I can automate the shit out of every old-school manual process. My pipelines work so hard that I can frequently spend my time spinning on my chair and looking out of my window.
