About the Engineering Team

Our cross-functional development teams always follow best software development practices - we solve our customer’s most pressing issues each sprint. We’re fast to roll out releases, but make sure everything is smooth. We strongly encourage ideas and innovation and share these during our internal Tech Talks. The cornerstone of our business is data. We process it in real time. On top of that, we react fast to API changes of social platforms but we’re ready to take on challenges and enjoy them.

On the front end, we’re using the React-Redux ecosystem built on leading quality UI components with a passion for UX and performance. On the back end, to keep the clients’ satisfaction high, we’re managing hundreds of Node.js APIs and microservices. Our data platform team uses Node.js services in combination with in-memory queues and storage. We also use several databases, like ElasticSearch, Hbase (+Hadoop), DynamoDB, MongoDB, Redis, and PostgreSQL. Ready to join our dynamic environment? We’d love to hear from you!
