Lift Application Development Cookbook

http://www.packtpub.com/lift-application-development-cookbook/book
Lift Application Development Cookbook teaches you how to build web applications using this amazing framework. The book moves gradually, starting with the basics (starting a new project, submitting a form, and so on) before covering more advanced topics such as building a REST API and integrating your application with other technologies and applications.

eFluence

eFluence is an application I'm building to help freelance teachers.

The application helps teachers to organize their students activities and allow students to build their own customized dictionary.

It uses Haskell and PostgreSQL in the back-end and React.js in the front-end.
