Ask HN: Please recommend a good custom software development company from Poland

Do you have any software development company from Poland or Estonia that you can recommend to me for cooperation? I'm looking for someone to whom I can outsource either entirely product development or, as a last, do a team extension.

Currently, we have a device prototype for the deaf and mute, and a mobile application with ready-made API interfaces. We want to create a dedicated web application to receive and process the data sent from the phone.
