Back-End dev - full time(30 hrs for 3 months)

Hello, we are seeking an experienced Backend developer to build the very first version of a Backend for a new kind of Psychology-based fitness app.

The app's end users will primarily be on mobile, but at a later stage, there will be a web interface added displaying the mobile users' data.

The backend technologies for this project have not been determined yet. I'm open to technologies. It is important for me to leverage 3rd party services for the MVP when reasonable.

I'm interested in a long-term relationship.

We will do a technical interview.

Thanks.
