Work environment

On the backend, we run a service-based architecture implemented with Java/Spring stack. We persist our data in both relational (MySQL) and NoSQL datastores (Redis, MongoDB, ElasticSearch).

Our high-traffic production environment comprises of more than 700+ virtualized Linux servers sustaining tens of millions of daily searches.

We have dedicated tech coaches that will offer you a helping hand in case you get stuck with a technical problem.
