Hi,
I'm a developer from Poland having experience in building scalable web platforms/applications. I worked as a team leader for an American (New York-based) startup before.
Could you shed some light on the details of this digital health web app?
Do you want a mobile application (Android/iOS) to be build on top of the web application as well? I think it would be a powerful enhancement of the Web application functionality.
My experience includes multiple different technologies, including, but not limited to: Ruby on Rails, PHP (Laravel framework), AngularJS, ES5/6, Sass/Compass, Amazon Web Services (with automatic configuration by Chef scripts), SQL databases (MySql and PostgreSQL) and also Java (for Android mainly). I can work on an hourly-based or project-based rate.
If possible, I'd love to discuss the project details on Skype or Google Hangouts - I speak fluent English. Please reach me here on Freelancer, so that we can arrange for a meeting.
Kind regards,
Tomasz.
